Gunfire erupted at a nightclub hosting a swimsuit-themed party for teens in Florida, leaving two teens dead and at least 17 other people wounded, officials said Monday. It was not immediately clear what triggered the violence, but Fort Myers police Capt. Jim Mulligan said the shooting was not an act of terror. The violence at Club Blu happened about 12:30 a.m. Monday, just as the club was closing and parents were arriving to pick up their children. The shooting comes more than a month after a nightclub shooting in Orlando that was the deadliest shooting in modern U.S. history. The shooting at the Pulse nightclub on June 12 left 49 victims dead and 53 others wounded.
