In this picture released Thursday, Nov. 28, 2013, and posted on the Facebook page of a militant group, a member of the al-Qaida linked Islamic State of Iraq and the Levant (ISIL) gives a lecture at the Engineering College in the northern city of Raqqa, Syria. The growing muscle of an al-Qaida linked Syrian group is casting a grim shadow over northern Syria, where extremist militants have turned their attention to seizing activists who cover their country's war on its front lines.
