London's mayor has announced that a book of condolence will be opened and a relief fund established for the victims of the London bombings.
The blasts have shocked and appalled the UK
Ken Livingstone called the bombers who brought terror and chaos to London on Thursday "cold blooded murderers".
He said he knew the city would be attacked one day but that the emergency plans "worked like clockwork".
Mr Livingstone said he will continue to use the Tube and urged Londoners to do the same.
At a press briefing he said: "I say to those who planned this dreadful attack, whether they are still here in hiding or somewhere abroad.

"Watch next week as we bury our dead and mourn them but see also in those same days new people coming to this city to make it their home, to call themselves Londoners and doing it because of that freedom to be themselves."
He added: "I believe it is the wish of Londoners that those who have suffered deaths of their loved ones or serious injury should also be helped by all Londoners.
"It could equally have been your son or daughter, your husband or wife, your loved one, or yourself who was struck.
"The overwhelming majority of us were lucky. But some Londoners paid a price for an attack on all of us.
"I know that the main job in caring for those who suffered must be carried out by the emergency services, by our health and support services all of whom showed again yesterday just what a debt Londoners owe to them.
"We cannot make up for what the victims have lost. But every single thing that can be done will be done."
The condolences book will be at City Hall from Monday and donations to the London Bombings Relief Fund can be made via the Red Cross.
