Suspect in Westminster attack is Muslim activist

Reports say the man behind the terrorist attack in London is Abu Izzadeen, a British spokesman for Al Ghurabaa, a British Muslim organization banned under the 2006 British Terrorism Act for the glorification of terrorism.

At least four are dead after Izzadeen drove a car into a crowd on the Westminster Bridge, then crashed near the British Parliament, where he stabbed a police officer. He was then shot by police.

We'll report on this more as details develop.
