Gunfire rang through the early hours of Sunday morning outside of the Pulse nightclub in Orlando as a lone shooter exchanged fire with hundreds of police officers parked outside. Footage courtesy of Anthony Torres captures the tense moments outside of the LGBT nightclub before SWAT police killed Omar Siddiqui Mateen, a 29-year-old American citizen of Afghan descent who had killed 49 people in the club in what is being called the deadliest terror attack on American soil since 9/11.
