Recall that about one hour before the attack, Stevens met with the Turkish Consul General Ali Sait Akin. Also recall that the major task of their Mission in Benghazi was to track and repurchase arms that had proliferated in the wake of Muammar Qaddafi's fall, including 20,000 missing shoulder-fired antiaircraft missiles.
Five days previous to that meeting, the Libyan-flagged vessel Al Entisar, was received in the Turkish port of Iskenderun - 35 miles from the Syrian border. According to a September 14 report by the Times of London, Al Entisar was carrying 800,000 pounds of cargo. Some of it was humanitarian, but it also included a large consignment of weapons headed for the Syrian rebels.
The Al Entisar was formerly a Korean fishing vessel, re-registered in Malta to “I-GO AID” in March 2011. They describe themselves as “a not-for-profit non-governmental organization (NGO) set up in order to deliver much needed medical and food supplies to the Libyan people.” During the Libyan uprising it ferried aid to rebels at the port of Misuratah. It was often stopped by NATO ships and boarded, but it was always sent on its way with no problems reported.
It is likely that Al Entisar was part of a CIA “Air America”-type operation providing covert support to the Libyan rebel forces. During those open-ocean NATO stops in 2011 they may actually have been loading weapons for the Libyan rebels. They may now be providing similar support for the Syrian opposition, but this time using Gaddafi's stockpiles. Stevens may have been in Benghazi meeting with Turkish Consul General Ali Sait Akin to oversee, negotiate, or inspect an ongoing covert CIA operation to supply weapons to the counter-Assad fighters.
There are many weapons that we do not want falling into the hands of Islamic rebel movements. These include Stinger shoulder-fired antiaircraft missiles; nuclear, biological, chemical and radiological weapons; and antipersonnel land mines. During the Libyan uprising, it was relatively easy to limit prohibited weapons if the Al Entisar was being supplied by NATO warships. Now, we have little idea what Gaddafi had in his inventory, and, with the Libyan-flagged ship ferrying materiel between Benghazi and Iskenderun, there is little direct oversight that is possible.
We will have to wait for more information to surface before trying to guess what, if anything, “the Turkish Connection” may have had to do with the attack.
