On this day five years ago: Suicide terrorist bombings in three Underground stations and a double-decker bus killed 52 victims and four bombers in the worst attack on London since World War II.
One year later almost a quarter of Muslims in the UK believed the attacks were justified.
Two years after the terrorist acts one-third of British Muslim Students polled indicated they believe killing in the name of Islam is acceptable.
In London, Islamic Radicals Found a Haven, the Washington Post wrote three days after the bombings.
