Online videos appear to show Iranian police and security forces firing tear gas and live ammunition to disperse demonstrators who protested the Islamic Republic's initial denial that it shot down a Ukrainian jetliner.

The videos obtained Monday by The Associated Press show show tear gas being fired on what appears to be a peaceful crowd, which then turns to run away. Gunfire can be heard in the background.

Another clip shows a woman being carried away as a crowd shouts that she's been shot.

The protests came after Iran belatedly acknowledged accidentally shooting down a passenger plane and killing scores of Iranians at a time of soaring tensions with the United States.
