The CIA’s new timeline of events in Benghazi is not holding up.

Both American and British sources say multiple roadblocks set up by fighters believed to be with Ansar al-Sharia were in place in Benghazi several hours before the 9:40 p.m. timeline and that communications also alluded to “heavily armed troops showing up with artillery.” Fox News was told by both American and British contacts who were in Benghazi that night that the CIA timeline rolled out this past week is only “loosely based on the truth” and “doesn’t quite add up.”

The safe room to which Ambassador Christopher Stevens retreated during the assault was far from safe.

One former Special Op now employed by a private company in Benghazi said that even the safe room wasn’t properly set up. He said “the safe room is one of the first measures you take” and that he is “not sure how you can set a safe room without fire suppression and ventilation in case of fire.” He also said, “Ambassador Stevens would likely be alive today if this simple and normal procedure was put into place.”

As details emerge of serious security issues before the attack on Sept. 11, Fox News is also beginning to hear more frustration from sources both on the ground in Benghazi and in the U.S. Multiple British and American sources insist there were other capabilities in the region and are mystified why none were used. Fox News was told there were not only armed drones that monitor Libyan chemical weapon sites in the area, but also F-18’s, AC-130 aircraft and even helicopters that could have been dispatched in a timely fashion.

British intelligence sources said that unarmed drones routinely flew over Benghazi every night in flight patterns and that armed drones which fly over chemical sites, some a short flight from Benghazi, “were always said to be on call.” American sources confirmed this and questioned “why was a drone armed only with a camera dispatched?”

Another source added, “Why would they put a ragtag team together in Tripoli as first responders? This is not even what they do for a living. We had a first responder air base in Italy almost the same distance away.” Despite the team arriving from Tripoli that night, sources said sufficient American back-up never came.
