Orlando, Florida (CNN)A gay nightclub here was the scene early Sunday of the worst terror attack in U.S. history since 9/11.
* 50 people were killed inside the Pulse club and at least 53 people were injured, police say.* The gunman was Omar Mateen of Ft. Pierce, Florida, a law enforcement source told CNN.* Orlando police shot and killed Mateen.* Mateen called 911 around the time of the attack to pledge allegiance to ISIS and mention the Boston bombers, according to a U.S. official.
I don't know what else to say without wanting to puke. This needs to stop. Absolutely heartbreaking.
