On 2 May 2011, Osama Bin Laden, who had led the Islamist al-Qaeda organization responsible for violent attacks on the United States on 11 September 2001, was killed in Pakistan by US forces. On 7 May, hundreds of UK Muslims and MAC members held a rally and Salat al-Janazah (funeral prayer) for him outside the US embassy in London. When protesters tried to storm the embassy, there were clashes with police.
