FILE - In this Wednesday, May 11, 2011 file photo, American-born Islamist militant Omar Hammami, also known as Abu Mansur al-Amriki, speaks during a news conference held by the militant group al-Shabab at a farm in southern Mogadishu's Afgoye district in Somalia. Hammami - whom the FBI named as one of its most wanted terrorists in November - has engaged in a public fight with al-Shabab over nearly the last year and may soon find himself the one pursued by insurgents.
