It happened last night at the crowded bar's closing time. Approximately 50 dead and another 50 - 100 wounded, many of them critically. They are calling for blood donations. The shooter was a man named Omar Seddiq Matteen, a US-born US citizen with Afghan immigrant parents. He was 27 years old, married with a wife from Uzbekistan, and was a licensed security officer with a special Florida firearms licence and firearms training. His father said that the sight of gay men kissing made his son angry, but denied that the attack had anything to do with religion. The FBI was already aware of Omar, they say that he did have radical Islamist leanings (and perhaps contacts with ISIS), the FBI investigated him in 2013 and 2014, but there weren't any current investigations underway concerning him. http://www.thedailybeast.com/articles/2016/06/12/omar-mateen-id-d-as-orlando-killer.html http://abcnews.go.com/US/omar-mateen-suspected-orlando-night-club-shooter/story?id=39790797 Just a few days ago Islamic State internet accounts warned of a coming attack in Florida to coincide with Ramadan. They are showing Mateen's photo on their websites and boasting about the attack. It's still unclear whether they pre-planned it or whether this is another 'lone wolf'.
