BEIRUT (AP) — The unsteady, hand-held video shows several bloodied prisoners, one in boxer shorts, being led into a noisy outdoor crowd and placed against a wall. The prisoners crouch and seem to avert their eyes as men carrying assault rifles shout slogans and take aim. The gunfire lasts for more than 30 seconds.

The international community has accused Syrian President Bashar Assad’s forces of war crimes, but the gunmen in this gruesome video were rebels. Their slogans: “Free Syrian Army Forever!” and “God is Great!”
