Benghazi: Obama watched as they were murdered

Navy SEAL Tyrone Woods was later joined at the scene by fellow former Navy SEAL Glen Doherty, who was sent in from Tripoli as part of a Global Response Staff or GRS that provides security to CIA case officers and provides countersurveillance and surveillance protection. They were killed by a mortar shell at 4 a.m. Libyan time, nearly seven hours after the attack on the consulate began -- a window that represented more than enough time for the U.S. military to send back-up from nearby bases in Europe, according to sources familiar with Special Operations. Four mortars were fired at the annex. The first one struck outside the annex. Three more hit the annex. 

A motorcade of dozens of Libyan vehicles, some mounted with 50 caliber machine guns, belonging to the February 17th Brigades, a Libyan militia which is friendly to the U.S., finally showed up at the CIA annex at approximately 3 a.m. An American Quick Reaction Force sent from Tripoli had arrived at the Benghazi airport at 2 a.m. (four hours after the initial attack on the consulate) and was delayed for 45 minutes at the airport because they could not at first get transportation, allegedly due to confusion among Libyan militias who were supposed to escort them to the annex, according to Benghazi sources. 

The American special operators, Woods, Doherty and at least two others were part of the Global Response Staff, a CIA element, based at the CIA annex and were protecting CIA operators who were part of a mission to track and repurchase arms in Benghazi that had proliferated in the wake of Muammar Qaddafi's fall. Part of their mission was to find the more than 20,000 missing MANPADS, or shoulder-held missiles capable of bringing down a commercial aircraft. According to a source on the ground at the time of the attack, the team inside the CIA annex had captured three Libyan attackers and was forced to hand them over to the Libyans. U.S. officials do not know what happened to those three attackers and whether they were released by the Libyan forces. 

Fox News has also learned that Stevens was in Benghazi that day to be present at the opening of an English-language school being started by the Libyan farmer who helped save an American pilot who had been shot down by pro-Qaddafi forces during the initial war to overthrow the regime. That farmer saved the life of the American pilot and the ambassador wanted to be present to launch the Libyan rescuer's new school.
