PHOTOS Of The Victims�Murdered By An ISIS Fanatic As They Partied At A Gay Nightclub

These are the victims of the worst mass shooting in American history.

Terrorist Omar Mateen shot dead 50 people and wounded at least 53 more during the massacre at the Pulse nightclub in Orlando in the early hours of Sunday morning – and called 911 just before the attack to pledge allegiance to ISIS.

Mateen, 29, of Port St. Lucie in Florida, reportedly laughed as he sprayed bullets into the crowded club before he was shot dead by a SWAT team several hours after launching his horrific massacre with a legally bought assault rifle and pistol.
