CIA still speculating on how Benghazi annex was attacked

Eli Lake:

More than eight months after the 9/11 anniversary attacks on the U.S. mission in Benghazi, Libya, the CIA is still trying to find out how the attack that killed two former Navy SEALs at the agency’s annex transpired.

The attack on the CIA base came more than seven hours after an armed mob stormed the U.S. diplomatic mission in Benghazi, setting the compound ablaze and killing U.S. Ambassador to Libya Chris Stevens and Sean Smith, a State Department communications officer who was with him.

On Wednesday, Deputy CIA Director Mike Morrell—along with CIA officers who were at the Agency’s Benghazi base on the night of the attack—testified at a classified hearing before the House Permanent Select Committee on Intelligence. In the closed hearing, according to U.S. officials with knowledge of the proceedings, Morrell was asked by Republican members about how the second wave of attackers knew to go to the CIA annex, which was a mile away from the diplomatic mission. Morrell responded that at this point the CIA did not know whether the attackers had known the location of the annex or learned about it on the evening of the attack, according to these sources.

The attackers fired five mortar rounds within 90 seconds at 5:15 a.m. on September 12, according to the State Department’s official review of the Benghazi incident known as the Accountability Review Board (ARB). The last three mortar rounds hit the roof of one of the CIA annex buildings, where two CIA contractors and former Navy SEALs, Tyrone Woods and Glen Doherty, were keeping watch. Both men were killed by the mortar fire; another diplomatic security officer standing watch on the roof was severely injured, nearly losing a leg.

I think it is likely that the terrorist followed the CIA team that mounted the rescue at the other facility.  They appear to have bided their time waiting for the rescue team at the airport to show up before making their attack.  Whether they already knew about the facility or found out about that night, they showed a sophistication in the firing of their mortars that suggest they were not just some street mob.
