On 12 June 2016, 49 people were killed and 53 others injured in a mass shooting at Pulse gay nightclub in Orlando, Florida, in the second-deadliest mass shooting by an individual and the deadliest incident of violence against LGBT people in U.S. history. The shooter, Omar Mateen, pledged allegiance to ISIL. The act has been described by investigators as an Islamic terrorist attack and a hate crime, despite the revelation that he was suffering from mental health issues and acted alone. Upon further review, investigators indicated Omar Mateen showed few signs of radicalization, suggesting that the shooter's pledge to ISIL may have been a calculated move to garner more news coverage. Afghanistan, Algeria, Azerbaijan, Bahrain, Djibouti, Egypt, Iraq, Iran, Pakistan, Saudi Arabia, Turkey, Turkmenistan and United Arab Emirates condemned the attack. Many American Muslims, including community leaders, swiftly condemned the attack. Prayer vigils for the victims were held at mosques across the country. The Florida mosque where Mateen sometimes prayed issued a statement condemning the attack and offering condolences to the victims. The Council on American–Islamic Relations called the attack "monstrous" and offered its condolences to the victims. CAIR Florida urged Muslims to donate blood and contribute funds in support of the victims' families.
