Truthloader has a video alleging that members of the jihadist Islamic State of Iraq and al-Sham (ISIS)- one of the many al-Qaeda linked groups fighting in Syria- executed seven so-called moderate opposition fighters from the Ghurabaa al-Sham Brigade, including their Commander Hassan Jazera. Jazera was accused of looting and being corrupt, but who knows what the truth is. The Ghurabaa al-Sham Brigade have been fighting from the start. They just like to kill.

Then of course you have the jihadists who accidentally beheaded one of their own. Oops. That time it was two foreign fighters with the Islamic State of Iraq and the Levant (ISIL) who beheaded Mohammed Marroush, a jihadist with the Ahrah al-Sham Brigade. Ahrah al-Sham is supposedly an ally of ISIL. A Tunisian was arrested by ISIL for mistaking Marroush for a Shiite Bashar al-Assad fighter, and subsequently chopping off his head. The other guilty party, from the Gulf, remains free.
