More than 50 people have been killed and hundreds injured in a series of bomb blasts that have hit the Underground network and a bus in London.
This is a third page of your comments.
The following comments reflect the balance of opinion we have received so far:
I work at Aldgate, about 150 yards from the station, the emergency services were just brilliant, we are so lucky that we have such professional people doing the hardest of jobs, I can't begin to imagine how the families and friends of those poor people who lost their lives must feel, I would also like to say thank you to the people on this page from all over the world who have voiced their support and love for us in this terrible hour, yesterday I felt proud to be a Londoner and British, today I feel 100 times prouder because I know we will fight back and show the terrorists of the world that they can never beat because you can never surrender to cowards, all they do is make us forget petty differences and unite us, just look at the comments on this page from all over the world.
I work in the heart of Central London. We first knew something had happened when some staff didn't turn up for work at the usual time. Nothing can compensate those who were wounded or lost loved ones. But I am proud that as the picture of the day's events started to develop, we carried on business pretty much as usual. Painfully aware of the suffering so nearby, people were generally determined not to let the attackers beat us. According to extremist websites, London is "burning with fear". It is not. It is sad and angry. But more importantly, it is carrying on almost as normal.
Greg Jackson, London, UK
I just want to send out my love to all of London. Today I feel more impotent than I ever have. From a UK citizen living in the US right now, please know that as far away as the US is, it is feeling as much sorrow as the UK. Stay brave.
Alexandra, Colorado, USA
I'm quite amazed by the resilience of Londoners. We were let out of the office early and I had made up my mind to get home walking if I had to, I was not going to take the bus after seeing photos of the blown up double decker. I was surprised seeing so many fearless Londoners jumping on buses as if nothing happened! Amazing spirit.
I am a Muslim born and raised in England and watched with horror the scenes from London. My prayers are with the families of those whose loved ones have passed away or are injured. We all need to unite, regardless of colour, race, religious beliefs etc. in order to show these cowards that we will not be beaten.
Ifzal Khan, Brierfield, Lancashire
I was horrified when I saw the news this morning. My daughter was at her first job behind Russell Square and I felt so concerned about her. She later said she was 5 minutes from getting on the bus that was destroyed. Thank God she is safe. My heart goes out tonight to those who have lost loved ones.
Ritson Shields, London
I was shocked and horrified to find that this act of terrorism has claimed lives of so many people. I lived closed to Tavistock Square whilst studying at the University of London. I cannot believe what I am seeing on the television. This is more than an act of terrorism; this is evil in its essence. May God bless everyone who has suffered. We must not give in. We must remain strong in this very sad moment in the history of Europe and the world.
It was a strange day. Everything unfolded just after I got off the tube so luckily I was unaffected until home time when I walked an hour and a half back to the Isle of Dogs. What is amazing is that people were happy to do this - London has not been brought to its knees as was the intention. My thoughts are with the injured and the dead and their families tonight.
Kevin Jepson, London
I have only recently moved back to Australia. If I had been working still in London, at that time of the morning I should have been on the Circle Line getting to the Barbican. It took over two hours to make sure all of my family and friends were OK. My heart goes out to all Londoners and the people who work in the city who have been affected. But knowing Londoners and the like, we pick ourselves up and get back to work.
Tina, Canberra, Australia
I have lived and worked as a surgeon in the UK for three years. News of the blasts was like a physical blow for me. My prayers go out to the dead, the injured and their families. As a Muslim and a Pakistani, I strongly condemn this dastardly act irrespective of who was responsible. Nothing can ever justify murder. Not in London or Barcelona nor in Baghdad and Gaza. Let us distance ourselves from purveyors of hate and cut them out like the cancer they are.
Sohail Muzammil, Lahore, Pakistan
The people in Houston, TX, are praying for you. Thank you for setting such an amazing example of how people should react in a situation like this. I admire you all.
Kristie, Houston, Texas, USA
God bless each and everyone in London and know our prayers are with you. You're a great nation but please know that there are many Americans ready to stand up and help you, just as you did for us on our 9-11. Again, God bless, and don't forget you have friends across the pond.
John Hickson, Orlando Fl. USA
I was shocked and saddened this morning as I read the news of the bombings in London. Having lived in England for over five years, I love and treasure the city of London like my own. My thoughts and sympathies go out to the families and friends of those who lost their lives in this horrific act of terrorism. I admire the courage and spirit of Londoners and the British people, and their ability to face such tragedy with determination, the British way.
Emily, San Francisco, USA
I was on the train immediately before the one at Aldgate. We were lucky in that we were at Liverpool St station when the blast happened and managed to walk out ok. I am proud of the calm way everyone coped - there was no panic. It showed what cowards these animals are - they won't win because you can't break our spirit
I really don't know how to express myself. I feel that I am angry about what happened today in London. This is an absolutely outrageous inhuman uncivilised acts. I have spent four years in London. I love this city and the people of it. We people of Algeria we are with you with our thoughts and hearts. Peace peace peace, inshallah.
I tuned into Capital FM on the internet expecting to hear people in shock and fear. What I found was the people of London bearing this with great courage and strength. I shouldn't be surprised at this from people who weathered the bombings of World War II. Our thoughts and prayers are with you.
Jim Shelley, Tulsa, Oklahoma, USA
I would like to send my deepest sympathy to the people of London from Istanbul, a city that shared the same tragic destiny two years ago. I'm now praying for those injured and for those lost their lives in this tragic event. My heart goes to the innocent people of London.
Aytac Eken, Istanbul Turkey
My thought and wishes are with all the people injured and the families of those killed. My husband and I have just returned home from London. Our stay there included lots of trips on the underground and the double-decker buses. We are so shocked and angry about what has happened. Hopefully, the maniacs who did this terrible thing will be caught and punished.
Jane Fisher, Mill Park, Victoria, Australia
I was in London today and feel very proud at how people handled a very worrying and difficult situation. There was no panic at all. The terrorists will never win and that's a fact.
I can't put into words how utterly devastated I feel for the people who lost their lives today. My thoughts are with their families, whose lives will now be changed forever. I walked home, from work to South East London, tonight and didn't feel inconvenienced at all, I just felt lucky to be alive.
So often you here people bemoan the fact that the British have lost their national identity, and our culture is slowly becoming eroded. But the events of the day have shown and perhaps defined what our national identity really is. We are a nation of people who, in times of adversity, put aside our differences and pull together. Who can collectively take a blow and still come back fighting. This is a sad time for all, but we Brits will soon get over this and carry on living our lives. We won't forget today, but when we come back we'll be stronger... and that's why there's a Great in front of Britain.
I am sending my deepest condolences for all the Londoners. My heart and thoughts are with you. I lived and was educated in London, and I feel so close to you. May you continue true to your British way of life which is remarkably rational, and admirably intelligent. I am so glad that Mr Blair has not used the expression of 'hunting down' the terrorists. I am absolutely sure that you shall prevail and they shall not.
Keiko Yamauchi, Kobe, Japan
I am so shocked and saddened by this. I have lived in London and to imagine that all these innocent people taking public transit on their normal everyday lives and suddenly this happens. My thoughts are with London today, for everyone, because even if you don't personally know someone that was physically hurt, an attack such as this hurts lots of people.
Carmine Bernhardt, Vancouver, Canada
Just to say that my heart and thoughts are with London and with all the Londoners. I lived in Ipswich for almost two years and I feel so close to England. I have been living in Madrid all my life and unfortunately I know what bombs and blasts are like. We lived through the same thing a year and a half ago. I am suffering for all of you. Never surrender.
Myriam Bernal, Madrid, Spain
My prayers and thoughts are with you tonight. I want to commend both the people of London and the city leadership for their courageous and organized response to this horrific event. I believe US cities, including my own, could learn a great deal from how London coped today. As time passes and things return to normal, never forget that you kept your heads about you, and that in so doing you probably saved lives. I know you all sent a shining example to the rest of the world.
Joyce McGinnis, Washington, DC, USA
Most people here in Egypt have been affected badly by what happened today in London... we feel sorry for people there. I have friends who live there and once I heard about the blasts, I called them immediately and they said they were fine thank God! Britain is a great country, where Christians and Muslims live in peace with each other... I hope something like this doesn't affect that peace in Britain.
Noura, Cairo, Egypt
I am 13 and today when I was in school I got the news that bombs had gone off in central London. I go to school in south east London, only about 20 minutes from the city. My mum works in the city and I started to get really worried. The phones were down so I couldn't get hold of her.
Finally I did and I thank God that she was ok. Also my friends' family were ok so I am really pleased. I give sympathy to the people who had not been so lucky. I also want to say well done for the walking wounded for not panicking and making the situation worse. RIP to all the lives that were lost today in London. I pray for you all.
I would like to simply express my pride in Londoners today. Their calm approach, their camaraderie, and yes, sardonic humour throughout the day represents all that they stand for. I at no time felt threatened surrounded by my fellow Londoners because of their immense qualities. Armed with this, I felt happy taking a bus home today, and confident that in the coming days we will all stand up to these atrocities by showing those who wish to harm us that we will mourn our dead by honouring them by continuing.
As a Londoner - from East London and having terrorists attack my home ground should have worried me... it didn't because the support of people worldwide, utter professionalism of the Police and London Transport have assured me that we can be as safe as we practicably can be in this day and age. And like so many of my brothers, sisters and neighbours in this city - we will continue to work, live and fight for a better future for all - whether they be in Africa or Aldgate. We have not woken up too late to this - just been stirred a little!
Dan Roberts, Bethnal Green
I've been working for Rail Enquiries today and I just want to say thanks to everyone who called and was patient with us and understood that we had limited information on what was happening in London. All of us in the office send our thoughts and prayers to those involved.
Helen, Plymouth, UK
I was not directly affected, but I work on the trains from Scotland to London. I want to send my thoughts out to the victims of these atrocities and those in the emergency services and those who work in the places affected. And especially to those who work in King's Cross, I hope you are all safe and I will see you soon.
William Palmer, Edinburgh, Scotland
I get into Liverpool St Station at 8.50am each morning but hit the snooze button for a 10 minute lie in so missed the blast. London has been a very surreal place today. Everyone has been incredibly calm. As a Muslim and a Londoner, this attack was aimed at all of us. My thoughts and prayers are with everyone affected today. Let's keep strong and let's keep together.
I have only been living in London for four days and have put a candle on my window sill to show solidarity with Londoners. This is not religious and irrespective of race and colour. This is about community and citizenship. Put a candle in your window and show that we are not beaten tonight.
I commute to London from Cambridge, and I am very grateful to WAGN that they managed to get trains going again from Finsbury Park to Welwyn Garden City and then on to Cambridge. I'm extremely glad to be home! The other commuters trying to get home were all very patient and good-tempered about the difficulties, and the WAGN staff were doing an excellent job of making regular announcements and explaining what was going on. I had expected to be trapped in London overnight, so it's a great relief to have been able to get back.
Eleanor, Cambridge, UK
Please pray for my best friend Mustafa who is badly hurt and having surgery at Paddington St Mary's this evening. These perpetrators who ever they are had no mercy, value for life and are real cowards.
Muhammed Isfahan, London, UK
I work in 1 Canada Square and the place seemed like some sort of fortress with security all over the place and doors locked. Getting the boat to Battersea, at first there was an organised line, but just ended in a cram to the boat gate like CW was sinking! I would like to thank the riverboat employees for their professionalism and high spirit in light of such an horrific action.
Daniel W, Canary Wharf/Battersea
I was in London last weekend for Live 8. I was so upset by today's news because I was in one of those trains just a few days ago. My heart and thoughts are in London.
Yannis Poulios, Thessaloniki, Greece
Thanks to the emergency services for their great work. My mum is still in Russell Square and cannot get back home tonight; however we are happy that she is at least alive.
Peter, Grays, Essex
I pass out my heartfelt condolences to all those affected by this bombing. Thanks to the well executed emergency plan and the close proximity of hospitals in the centre of London the casualties were dealt with effectively. Following two bomb scares in Edinburgh today, I have to question if there would have been a greater loss of life here had the same incidents occurred in Princes Street. The city's only Accident and Emergency is at the flagship Royal Infirmary Building, around five miles away from the city centre.
Grahame Case, Edinburgh, Scotland
I work in the city and I usually get the Piccadilly line from Hammersmith to Holborn. This is an atrocity against humanity, as I was looking around me people were trying to get into work, school etc and everyone was a target. It's ironic because I am originally from Baghdad and I feel deep pain for what has happened in London and everything that is happening in Iraq. I hope that we can all be stronger than terrorism and I hope that we can all be united despite our colour, race, or religion against this evil force.
Sally al Aqidi, London
My deepest sympathy goes out to the people of London. I have been listening to BBC Radio all day and watching news clips online of all the terrible things that happened. I couldn't help but be reminded of September 11 because on that day nothing but sirens could be heard all over NYC just as I see in London now. I know people who passed on 9/11 and we must, for their sake and for the sake of those who have just passed (7/7), stick together and overcome this. My prayers are with the only city that could ever compare to NYC.
Albert Lagnado, New York City, USA
We will fight in our trains, we will fight in our buses but we, Londoners, will never surrender!
George Justo, London
Although I wholeheartedly agree that it must be extremely difficult to prevent a terrorist from carrying out an atrocity if they are determined to commit one and that the only people that should accept responsibility are those that perpetrated it I can't help feeling that our intelligence sources knew something was afoot.
Yesterday late afternoon, my partner and I drove back through London after a mini-break to Brighton rather than face the M25. Hackney seemed to be crawling with police cars and I even saw an armed officer patrolling the streets, which seems ironic considering the bus involved in the blast at Tavistock Place has been reported as the number 30 Hackney to Marble Arch service.
I am only 14 and I heard about the devastating attacks in London at school. I cannot imagine the pain to those that have lost family or friends as I myself was extremely worried as both my parents work in Canary Wharf. I would also like to take this opportunity to thank the emergency services for their fantastic dedication and effort into helping the people of London today.
Hannah Liu, Mill Hill, London
I was getting ready to go an interview when I heard the explosion. At first I wasn't too sure what happened. Then I got a call from a friend yelling down the phone for me not to leave the area, there was a problem in my area. The bus blast was outside my window. Within seconds a mass of people came streaming in from the Russell Square tube station. Police had the area sectioned off, and ushering people in doors and telling us to close the doors and windows. It's weird looking outside my window onto a street that is usually busy with people no matter the time of day... now you could almost hear a pin drop.
I live in Central London on a main road. There have been lots of police cars racing past my front door, even six hours after the attacks. They surely can't be responding to this morning's attacks and it makes me wonder if there are other threats which aren't making it to the news. My husband works in the city, and although I am thankful he has been off work this week, I am dreading his going back on Monday.
Lauren, London, UK
I was travelling into work this morning, and I normally travel on the Victoria Line to Kings Cross and then change to the Northern Line. As I passed Kings Cross and got to Camden Town, while walking towards the platform - I heard a faint bang. I thought it was just workers working on the trains and maybe something fell?
When I got to work I found out what had happened and I couldn't believe I had just missed it and I am still in shock. I just thank God Almighty that I changed on the earlier train at Kings Cross and left. I hope they catch whoever did this. My thoughts are with those who were actually caught up in it all.
Azra-Tayyaba Mehmood, London
My husband was working on the Underground when this all started up, he helped evacuate and answer questions, guiding people to safety. I think that the press should show some gratitude and acknowledgement towards the brave people from the public transport who helped rescue people, putting there own lives at risk to help others.
Grace Milsom, Colindale, London
I can only offer my prayers for the people of Great Britain right now, and most especially for the victims and their families. As one who considers England a close friend, I ache for you. I know the people of London have bravely weathered the German blitz and IRA bombs. If there is a city - if there are a people - who can withstand this senseless and futile form of terror, it is London and its residents.
George, New York City, USA
Let us be grateful for what we have and the response and professionalism of our emergency services. The terrorists will not stop us, just strengthen our resolve. Long live London. Long live Britain. Long live Freedom.
Michael Robbins, London
I am only 11 but the terrorist attacks have affected me and literally all of the people I know, most of my friends' parents and older siblings were on the tube or bus at the time of the attack and are devastated.
Ilse, London, UK
My heart goes out for those that have lost loved ones and friends. I was on my way in to town and thought nothing of LU's first reports that there had been a series of power surges that knocked out the network. Consequently I thought nothing of the report and carried on my attempts to get in.
Had I instead been told there were some unexplained explosions on the network I would have immediately returned home. Surely one question that must be asked is how LU got it so wrong to start off with. If they didn't know they should have said so, and we could have drawn our own conclusions.
Mike, London, England
I was at Paddington between 10.30 and 1.00. There were two sorts of travellers, those wanting to carry on with their business, and those taking any train to get them out of London. Most passengers on the train I arrived on stayed put, creating chaos when those wanting to take their reserved seats arrived! At about 11.15 alarms went off and the station was evacuated.
People initially moved slowly, and then ran in panic when staff screamed at them to get out. Outside people stayed close to see what was happening, but soon moved on as police arrived to usher them to safety. Several contingency ambulances arrived and, eventually, the sniffer dog to rescue us all from a false alarm. Trains to get people away from the area arrived remarkably quickly after the station reopened. I was impressed by the emergency services, apart from the obvious lack of sniffer dogs, they were calm and in control throughout. Some station staff do need extra training, however. They could have caused a serious panic.
Today is a sad day in London and the world at large. My sympathies to the people affected.
Chris, Bissau, Guinea Bissau
Why don't you ever post anything vaguely critical of the BBC ! The coverage today was appalling only late in the day was there any helpful advice for people trapped in the zone.
Nick Thorpe, UK
It took me 4 hours and 5 buses to get home from the Isle of Dogs - but London Transport got me there. Well done to TfL for keeping services outside Zone 1 as normal as possible. My heart goes out to everyone involved in the rescues.
Kirsty Sullivan, Epping, Essex
My best friend is stuck at Russell Square as she was evacuated from her home. I want to go and pick her up, I know she's alright but she can't go home, I should be with her.
My sincere condolences for the British people. But the British people must be stronger at this moment of pain. I am sad because the British people were attacked. And it is not fair.
Alessandro Cavalcante, Sao Paulo, Brazil
I am a nurse working in London, as the major incident was called. The professionalism of all the emergency services has to be commended! The NHS has been knocked a lot recently, but today proved how valuable our hospitals and their staff are. How they rise to the challenge of such a terrible act of cowardice needs to be applauded. London has known terrorism of some sort or another for many, many years, we have lost countless numbers of lives, and have had many wrecked. London and the British people have gone on despite all this, and will continue to go on. The British spirit will not fail or falter. My thoughts are with the many families that this tragic act has touched today.
I am a doctor and was one of the very first people on to the scene of the Woburn Street bus explosion. The carnage was devastating and the image will stay with me forever. Once I overcame my initial shock, I started trying to help the survivors along with the few other members of public there. Once the paramedics arrived, we had medical supplies available to patch people up as best as we could before they were rushed to hospital. This has been the most horrific experience of my life and hope I never ever see anything like this again. I do not understand how the murderers responsible for these atrocities can justify them in the name of their God. We must get London going again so that their attempts to terrorize us are in vain.
Julia Phillips, London
Just saw on the BBC the wonderful sight of London slowly trying to return to normal after an horrific day. Seems that, now a multi cultured London, just like 65 years ago takes this "on the chin".
Julien, Vlaardingen Netherlands
I took a silver link train from Kentish Town West right past King's Cross at about 0920. I could see a huge crowd and blue lights, but thought nothing of it assuming it was a traffic accident on the roads. It wasn't until I arrived at college in Islington and it became clear that our class was largely empty that the scale of the event became clear. The mobile network cells near us seemed to be still running, although with a very low call/text success rate. When the service got back on track my SIM card was filled within a matter of seconds with sms messages asking if I was alright. At the end of the lecture I walked home in the pouring rain.
I would like to see far less media coverage for these terrorist attacks. Continuous news coverage is helping no one but the terrorists who will be bathing in their success. These attacks should just receive normal news coverage or even less than that if possible. There were people who would be injured and some who tragically had lost their lives and I saw the media frenzy saying the same things over and over again as self indulgence. When London and other cities were being blitzed night after night during WW2 we were kept up to date in what we needed to know on the daily radio news broadcasts. All I now need to hear is that suspects have been arrested. Media hype will achieve nothing except pleasure for the terrorists.
Noel Dobson, York UK
My heart goes out to the casualties and their families especially as I am still waiting to hear that my sister is OK. I don't know how anyone can justify killing and maiming masses of ordinary people on their way to work.
Michael, Hartford, US
I was due to travel through Central London to Docklands for an event that was taking placed there but I overslept by 2 hours and turned on the TV and was sick at the sad pictures that was on my TV. My thought is with all those who are who are injured and also who loved ones died today and those.
Evonne Okafor, London
I felt the shockwave from the Edgware road blast as we pulled into the station from Paddington. My heart goes out to the people trapped in the tunnel, the injured and the families of those who died.
Everybody was screaming, jumping out of the windows, it was horrible, the worst thing that I have ever seen in my entire life.
Joscelynne, London, UK
The atmosphere along Euston Road this morning was very different to most. The pavements were packed with confused tube travellers and the roads gridlocked. I was surprised to see that the Police were even preventing pedestrians walking down towards Kings Cross (the direction I wanted to go). I tried to establish what was going on but the police were busy enough and so spoke to another pedestrian who confirmed that we could not go any further. So I was re-directed down Tavistock Street when a minute or so later I heard an explosion and saw a huge piece of red metal and lots of debris be propelled so high into the air in front of me.
Later I deduced this must have been the roof of the bus. People, including myself, seemed to remain fairly calm to begin with but later when I heard reports from other pedestrians about what they had seen I began to get quite emotional. It's an odd feeling being so close to such a horrific incident. If I hadn't stopped to find out about the detour then I dread to think how close to the blast I would have been. Perhaps even stranger was the feeling of being completely vulnerable and utterly trapped within London's vastness. I didn't know where to turn to and my mobile not working didn't help. My heart goes out to all those innocent people involved in the blast and to all their relatives and friends.
Cassandra Harwood, London, W1
We are community nurses and have had to help out in a school where the injured people are being taken to as the hospitals are jam packed. What a terrible day for London.
I would like to express my extreme gratitude to the London Underground staff, Fire Brigade, ambulance and hospital staff for their magnificent care and support for the passengers of the Piccadilly train disaster. I was on that Kings Cross train and for a moment I thought my number was up. However, I was extremely fortunate to only suffer minor breathing difficulties due to the smoke and soot inhalation. The after care at the Royal London Hospital was fantastic. Also a big thumbs up to the British public, people came together to help there fellow man and that really touched me. My thoughts are with the families who have lost loved ones and those who were injured in all the incidents in London.
Steve Jackson, London, UK
I have just read various messages from people frantically trying to locate their family and friends after this atrocity. I wish so much that each and every one of them locates their loved ones fit and well, although I know this can not happen. My thoughts are with the victims and their families tonight, I hope that they find comfort and that the terrorists who committed these attacks are brought swiftly to justice.
Ed B, Edinburgh
I am a tube driver who was working through central London this morning as the diabolical events happened. I am sickened as are my colleagues that our customers, ordinary working people should be targeted like this. As soon as the network is deemed safe I will be driving on the tube. Unfortunately it will be with a feeling of nervousness but nonetheless those responsible for the deaths will not stop us moving London. We all have a part to play to keep each other safe, please report everything suspicious to staff or police. Finally my thoughts are with the families of the victims of today's events and also with the drivers on the affected trains whose condition is still unknown to us.
I got home on the first Silverlink Metro to run from Camden Road westbound to Richmond, at about 3.45pm. It was eerily empty, while thousands of people were walking home.
I was on the train between Kings X and Russell Square - loud bang just about 100M out from Kings X - carriage filled with thick black smoke and plunged into darkness briefly - a few people freaked out but generally everyone was calm thinking it was a power surge - no idea that it was a terrorist attack - we evacuated out the back of the train about 30 mins after being trapped. The smoke made us think it was a fire at first but then the smoke didn't seem to increase and people thought it was just dust thrown up by the blast. The carriage was packed and claustrophobic.
Gurvinder Mahl, London
I was on the tube at Kings Cross when it was evacuated; the sight of the injured, blackened with soot, dirt and covered with blood is a vision that will stay with me for a long time. I had to get away from the scene so I walked towards Euston only to be told that there had been another explosion, but this time on a bus. It seemed like confusion was at every corner. It has taken me 4 hours to walk back to work, via the back streets and avoiding any buses or main roads. There has always been an air of fear; now it's real.
Alex Spreckley, City of London
I might be 9000 miles away but my thoughts are with my British family and friends in and around London. I am very grateful to not be living there anymore, but in a very isolated, small, clean and cosmopolitan city of one million from approx 60 different nations, on the other side of the world.
Nick Page, Perth, Western Australia
Everyone tried to call their beloved ones, but the mobile networks were down for most of the day.
All Canadians stand with you in solidarity. Our thoughts and prayers are with you all.
Brian Mitchell, Montreal, Canada
I was at my desk in BMA House, Tavistock Square when the bus exploded. We were all shocked by what has happened. I heard that the casualties were able to be 'treated' by doctors who were at BMA House at the time. I feel deep sympathy for those caught up in and affected by the day's events. It is so very distressing and mindless.
Clare Spencer, Islington, London
I was chucked off the tube at 9.30 this morning and the man next to me was cursing LFT - we just thought it was a normal day's trouble! Carrying on I made it to St Paul's by bus when I found out that the buses weren't going any further. I turned around and started to walk back to NW London, still thinking it was just a London transport problem. It wasn't until I got to Holborn that I found out it was more serious - that one bomb had gone off near where I was then, and that another had gone off near where I was heading. I was just determined to get back home, and it wasn't until I made it back safely that I burst in to tears - the shock of what was happening had just hit me. I really hope everyone else is okay, and my thoughts go to those people and their families who aren't.
Our hearts are with you today London. Please know that those responsible do not represent us in the Arab/Islamic world.
Sufyan, Doha, Qatar
Everyone is shocked by today's events, especially the transport workers who have had to deal with the worst that the terrorists have thrown at London - however why are there no plans in place to inform those inside London how the transport networks hope to aid people getting home today? It feels like we have been forgotten about!
Stuart Walker, London UK
This is so sad and ultimately so very, very pointless.
Barry, London, UK
This is a truly great city with a great spirit. We will not be defeated by cowards.
Paul, London, UK
To think if I had left just 10 minutes earlier this morning I would've been onboard one of those Tube trains. This is shocking and sickening and my thoughts go out to all involved. This is a major blow in the stomach after the high I was on yesterday after the Olympic results yesterday. This is just awful, sickening.
Liam Kenny, Greenwich
I was on the Piccadilly line when I got of at Kings cross. There was a loud sound of the back of a carriage that I was on. I was with my sister and was helping her overcome her panic attack. Everywhere was misty and so dark. There were people everywhere and there was screaming and chanting everywhere. It was a total blackout and the policemen and firemen were everywhere. Never have I been so terrified in my entire life as a Londoner
Usher, Victoria, London
This is such a sad day London was such a happy place yesterday. Our thoughts are with the family and friends of the victims. I just hope the individuals responsible realise that they will never ever win we will not let them rule how we live our lives.

Got herded off the underground at London Bridge. Live in East London will have to walk home - 6.5 miles. Haven't heard from my girlfriend who works at Liverpool Street/Aldgate. Getting no reply on her mobile. Praying she is safe.

Last night in Singapore, I was congratulating Ken Livingstone, Tessa Jowell, Lord Coe and Princess Anne on their successful bid. Now from that same stop Ken Livingstone made a moving speech on the attacks. London made us feel so proud yesterday and gave so much hope - we will rise above this stronger than before. That same spirit which won the games will prevail.

I just hope that the angry, frightened people don't turn on all the innocent, law-abiding Muslim families who live peacefully with us in our communities. These attacks affect them too, and they are just as scared and angry as the rest of us, without the added fear of being attacked purely because of their religion. My thoughts are with everyone affected, regardless of race, creed or colour - be strong, every right minded citizen of this planet is behind you.
