In late November 2010, Huthaifa al-Batawi, known as al-Qaeda (in Iraq)'s "Emir of Baghdad", was arrested along with 11 others in connection with the October 31, 2010 assault on Our Lady of Salvation Syrian Catholic church in Baghdad. Batawi was locked up in a counter-terrorism jail complex in Baghdad's Karrada district. During a failed attempt to escape in May 2011, Batawi and 10 other senior al-Qaeda militants were killed by a SWAT team.
