Syrian rebels reportedly shot down a regime combat helicopter in a town east of Damascus on Friday, according to opposition sources. The fate of the four officers aboard the helicopter was unknown.

The Syrian Observatory for Human Rights reported that rebels downed a “military fighter helicopter” that was flying above the Damascus suburb of Saqba. According to the opposition group, “the helicopter was taking part in the bombardment on the eastern Ghouta.”

Videos uploaded to YouTube claimed to show the helicopter aflame and plummeting to earth after being shot.

In one video the unidentified cameraman shouts “Allahu akbar! (God is greatest). The helicopter is falling!,” according to The Lebanese Daily Star, and another exclaims ”He hit it! He hit it!”

The Local Coordination Committees for Syria reported that 55 people were killed in Syria on Friday.
