WASHINGTON (AP) — The former head of a 16-member U.S. military team in Libya said Wednesday the consulate in Benghazi, where the U.S. ambassador and three other Americans were killed, never had the forces it needed to protect itself.

Lt. Col, Andrew Wood said in prepared testimony to the House Oversight and Government Reform Committee that U.S. security was so weak that in April, only one U.S. diplomatic security agent was stationed in Benghazi.

The committee hearing followed assertions Tuesday night by the State Department that it never concluded that the Sept. 11 attack stemmed from protests over an American-made video ridiculing Islam. Ambassador Chris Stevens and three other Americans died in what the administration now says was a terrorist attack.
