BENGHAZI, Libya (AP) — The attack that killed four Americans in Libya, including the U.S. ambassador, was an organized two-part operation by heavily armed militants that included a precisely timed raid on a supposedly secret safe house just as Libyan and U.S. security forces were arriving to rescue evacuated consulate staff, a senior Libyan security official said on Thursday.
Wanis el-Sharef, eastern Libya's deputy interior minister, said the attacks Tuesday night were suspected to have been timed to mark the 9/11 anniversary and that
the militants used civilians protesting an anti-Islam film as cover for their action.
Infiltrators within the security forces may have tipped off militants to the safe house location, he said.
He said an unspecified number of militants suspected of taking part in the attack have been arrested and that others were being closely monitored by police to see whether they are linked to a group. He refused to elaborate.
