Orlando Nightclub Shooting, USA (June 12, 2016). Deaths: 49
On the 12th of June 2016, Omar Mateen entered a gay nightclub in Orlando, Florida, shot and killed 49 people and injured another 58 in what remains the deadliest act of violence targeting LGBT people in United States history.
In a call to 911 during the shooting, Mateen identified himself as “Mujahideen”, “Islamic Soldier”, and “Soldier of God” and pledged his allegiance multiple times to Abu Bakr al-Baghdadi, the leader of the militant jihadist group – Islamic State of Iraq. He said the shooting was “triggered” by an airstrike in Iraq that killed Abu Wahib, an ISIL commander, six weeks before. It was later alleged that he was gay/bisexual and had visited the club a couple times. His sexual orientation may never be known though, as he was killed in a shootout with the local police that day.
