FILE - In this Wednesday, May 11, 2011 file photo, American-born Islamist militant Omar Hammami, 27, also known as Abu Mansur al-Amriki, right, and deputy leader of al-Shabab Sheik Mukhtar Abu Mansur Robow, left, sit under a banner which reads "Allah is Great" during a news conference of the militant group at a farm in southern Mogadishu's Afgoye district in Somalia. A U.S. State Department official who specializes in Somalia said Thursday, March 21, 2013 that the $5 million reward offered for Omar Hammami on Wednesday, March 20, 2013 could exploit what are believed to be fault lines between groups in Somali that may be for and against Hammami.
