And today is the first anniversary of the four London suicide attacks that killed fifty-two people. The anniversary is being marked with several events, including a two-minute moment of silence across Britain. This week, Al-Qaida released a video suicide note by one of the bombers. On the video, the bomber, Shehzad Tanweer, warns of further and more deadly attacks. Tanweer also says the attacks are justified because of the British government’s policies against Muslims in Palestine, Afghanistan, Iraq and Chechnya. Al-Qaida’s deputy leader, Ayman al-Zawahiri, also says on the tape that Tanweer and another bomber had been trained at the group’s camps. The tape’s release comes as a secret police document prepared by anti-terror specialists warns the war on Iraq has had a motivating effect on British Muslims planning acts of violence inside the country.
