The motion says that in the days preceding the attack, the defendant “voiced concern and opposition to the presence of an American facility in Benghazi.” According to the motion, a group of 20 or more “armed men,” including militia members, assembled outside the U.S. compound at 9:45 p.m. the night of Sept. 11, 2012, and “aggressively breached” the gate.

They carried rifles, handguns and rocket-propelled grenade launchers.

After breaching the gate, they stole a U.S. vehicle, “forcibly entered” buildings and stole U.S. property.

“During this initial attack, buildings within the Mission were set on fire,” the court document says, noting that the fires “ultimately led to the deaths” of U.S. Ambassador Chris Stevens and Information Management Officer Sean Smith.
