The suspected ringleader of the July 7 London suicide bombers visited Israel for a day in 2003. Citing an Israeli official, the news agency "Reuters" reported on Monday that Mohammad Sidique Khan arrived in Israel on 19 February 2003 and left the next day. The revelation gave weight to speculation that Khan may have helped to plan an 30 April 2003 suicide bombing by two fellow British Muslims at a Tel Aviv beachfront bar, which killed three people. British police believe Khan blew himself up aboard an underground train in London on 7 July, one in a series of deadly attacks in which 55 people were killed and 700 injured.
