1. ISIS claims responsibility for Orlando mass shooting

The Islamic State claimed responsibility for the murder of 49 people and wounding of 53 others at the Pulse nightclub in Orlando early Sunday morning. "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," the ISIS news agency, Amaq, 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. President Obama said the attack was "an act of terror and an act of hate."

2. Florida nightclub shooter had been investigated by FBI twice

The attacker in Sunday's mass casualty shooting at a nightclub in Orlando, Florida, had been investigated by the FBI twice in the past, authorities said. FBI assistant agent Ron Hopper said Omar Mateen came under investigation in 2013 when he made inflammatory comments to coworkers "alleging possible terrorist ties." He was interviewed, and then the case was closed. Then in 2014, Mateen was again investigated by the FBI due to possible ties to an American suicide bomber. However, he was not subject to an active investigation or under surveillance at the time of Sunday's shooting, which left 50 people dead and another 53 injured.
