Aleppo, Syria (CNN) -- Syrian rebels said Monday they shot down a military jet, an assertion denied by the government, which blamed the crash on a "technical failure."

Video posted by the rebel forces shows a jet framed in a cloudless sky being shot at, catching fire and falling out of frame.

"A MiG warplane shot down in Mouhassen!" says an excited man off-camera, citing a location in Deir Ezzor northeast of the capital city of Damascus. "God is great!"
