I recall early reports of a planned relocation by Libyan security, but I could be mistaken. Nonetheless, it doesn’t make sense.
The Ambassasdor was in the middle of being taken from the Embassy to a nearby compound which was thought to be 'safer', because the Embassy was under attack. Stories of the Ambassador suffering smoke inhalation and dying in the Embassy are total fiction.
It was during this trip that the convoy was ambushed by two squads of 10 mean each, equipped with RPG's and Automatic Weapons, who killed the Marines, the ex-Navy Seal, several civilians and the Ambassador. Except for the Libyan Security Escort, No one had ammo for their weapons. The Libyan Security Escort either ran, or filmed the attack on their cellphones. It was a professional hit and the 20 men were former 'terrorist' prisoners who had been released and recruited by Zawahiri and the Al Queda. (which is just a label, like all the others, for ORGANIZED CRIME). Significant 'benefits' were offered to the HIT SQUAD , such as new SUV's.
Is that the relocation you meant?
