Newly revealed testimony from top military commanders suggests that well-trained attackers executed the deadly dawn assault on a CIA complex in Benghazi, Libya, that followed the attack on the U.S. diplomatic mission the previous night.

The initial attack on Sept. 11, 2012, killed U.S. Ambassador Chris Stevens and a communications specialist and set the mission ablaze.

Nearly eight hours later at the CIA complex nearby, two American contract security officers died in a mortar attack. Retired Gen. Carter Ham told Congress in closed-door testimony released late Wednesday by lawmakers that the second assault showed clear military training.

According to the testimony, a new team of militants probably seized on reports of violence at the diplomatic mission the night before and hit the Americans while they were most vulnerable.
