‘Based on the best information we have to date … it began spontaneously in Benghazi as a reaction to what had transpired some hours earlier in Cairo, where, of course, as you know, there was a violent protest outside of our embassy sparked by this hateful video. But soon after that spontaneous protest began outside of our consulate in Benghazi, we believe that it looks like extremist elements, individuals, joined in that effort with heavy weapons of the sort that are, unfortunately, readily now available in Libya post-revolution. And that it spun from there into something much, much more violent…. We do not have information at present that leads us to conclude that this was premeditated or preplanned.’
