The Islamic State claimed responsibility for the murder of at least 49 people and wounding of 53 others at the Pulse nightclub in Orlando early Sunday morning. As of Monday, five people remained in "grave condition," hospital officials said. "The armed attack that targeted a gay night club in the city of Orlando in the American state of Florida which left over 100 people dead or injured was carried out by an Islamic State fighter," ISIS's Amaq news agency said Sunday. U.S. officials caution that there's no evidence the apparent shooter, U.S.-born Omar Mateen, had any direct ties to ISIS or was in contact with the Islamist terrorist group. ISIS encourages "lone wolf" attacks in the West, and an ISIS spokesman recently encouraged such attacks before the start of the holy month of Ramadan. [Reuters, The New York Times]
