In the shadow of the London bombings, hundreds of anti-war protesters and Muslims came together to send a "message of commiseration" to the victims and their families.
Black ribbons were in tribute to the bombings' victims
In the gardens of the Friends Meeting House in Euston, yards from the scene of Thursday's bus explosion and the tube blast at King's Cross, hundreds of people shared a two-minute silence - all wearing black ribbons in tribute to the dead and injured.
Saturday's vigil was called by the Stop the War Coalition, the Campaign for Nuclear Disarmament and the Muslim Association of Britain.
Present were the anti-war politicians MPs George Galloway and Jeremy Corbyn, along with poets, campaigners and ordinary people who wished to show they cared.
Mr Galloway said he was there as a "mark of respect" to those killed and maimed "by those criminals".
"These were ordinary people, heading for work, who were cruelly killed - and no-one can justify that," he said.
Muslim woman Yasmyn Atalluah, 31, said she wanted to "express her sadness for all the innocent lives lost".
"We are all part of humanity and it is a tragedy and I think it is important to come together and show solidarity."
Organiser Chris Nineham, of Stop the War Coalition, estimated around 1,500 people had come to the vigil.
"The whole population has the feeling 'it could have been me' and that is a terrible situation to be in really," he said.
He had arranged the event in just 24 hours, he continued.
"It is very important that the anti-war movement moves very quickly to make its statement, because it really is a case that peace is the only answer and as soon as troops come out of Iraq the better," he said.
Speakers repeatedly blamed the war on terror for the London attacks
But it was Dr Assami Tamimi, of the Muslim Association of Britain, who drew the biggest response from the crowd.
"This wasn't an attack on a certain creed or race. This was on everybody in London."
He told the BBC News website a "three-pronged" approach was needed to combat such attacks.
"Firstly, we have to be vigilant as citizens and co-operate with the security services.
"Muslims also need to kill the ideology behind this, that justifies the killing of innocents - this is Machiavellian and is anti-Islamic.
"And we need to pressure the government to change its policy. If we hadn't had the war in Iraq this would never have happened."
