FILE - In this Sept. 14, 2012 file photo, Libyan military guards check one of the burnt out buildings at the U.S. Consulate in Benghazi, Libya, during a visit by Libyan President Mohammed el-Megarif to express sympathy for the death of American ambassador to Libya Chris Stevens and his colleagues in the Sept. 11, 2012 attack on the consulate. The White House has put special operations strike forces on standby and moved drones into the skies above Africa, ready to strike militant targets from Libya to Mali — if investigators can find the al-Qaida-linked group responsible for the attack.
