An account associated with the Islamic State released gruesome footage on Tuesday showing the execution of several men. The video was allegedly taken in Iraq’s northern Ninawa province.

The stylized seven-minute clip depicts graphic scenes of at least 16 men, apparently held prisoner by the group, dying in a series of horrifying scenarios.

The footage was posted to an anonymous file-sharing site where the group often posts videos and photos and was branded with the now infamous black flag associated with ISIS.
