U.S officials say heavily armed extremists who laid siege to a U.S. compound in Libya this month used sophisticated, military-style tactics that may have steered Americans toward a waiting ambush.
Investigators piecing together how the compound was overrun say more than 50 attackers were responsible for the Sept. 11 assault on the U.S. consulate in Benghazi. Backed by gun trucks surrounding the compound, the militants' first attacks sent the Americans fleeing to a fallback building, where a second group hit them with precise mortar fire.
The attacks killed Ambassador Chris Stevens, and three other Americans.
The officials spoke on condition of anonymity because they were not authorized to discuss intelligence reports.
Officials have focused attention on Ansar al-Shariah, a Libyan militant group led by a former Guantanamo detainee.
