Syrian Rebels Say Extremists Behind Mass Execution

Vow to bring perpetrators to justice

A Syrian rebel brigade blamed "extremists" for a grisly massacre now gone viral on the Internet, and it vowed to punish the perpetrators.

Hossam al Sarmani, a spokesman for the Free Syrian Army's Daoud Brigade in northern Syria, said rogue revolutionaries carried out the killings in Idlib province.

"This execution did take place, and this is the heinous truth," al Sarmani told CNN on Friday. "We will find them, capture them and hold them in a prison until they can by tried by international law or the new Syrian law, God willing."
