Rally remembers London victims and draws attention to the plight of British Muslims
The rally, organised by the Muslim Association of Britain and the Stop the War coalition, attracted people from around Britain to listen to speeches by prominent members of the two groups.
Stop the War Coalition chairman Andrew Murray said: "We have called today's event for three reasons, the first is to remember the dead from the terrible outrages in our city, only a few yards from here on July 7.
"Innocent victims have lost their lives in an incident that proved how ridiculous the war on terror has been. The second reason is to express our solidarity and support for the Muslim community in Britain and the third reason is: we are not going to stop our campaign against the war on terror.
"We will continue to campaign for the speedy removal of troops in Iraq and we are going to fight for it harder than ever."
Wasar Altikriti, an 18-year-old from the Muslim Youth Group in Leeds the city where two of the bombers lived described feeling a sense of hate from travellers on the underground.
"I feel intimidated and threatened when getting on a bus or walking down a street," she said.
"Today as I journeyed from Leeds to King's Cross, the feeling of being branded as a terrorist and suicide bomber was most obvious through looks, utters and remarks of those who passed me by.
"Britain is my country as it is yours and its safety concerns me as it concerns you. My dear friends the Muslim community and in particular the youth have had to pay twice in the aftermath of the London attack."
