Authorities in South Carolina are investigating a shooting at a nightclub early Sunday that wounded at least nine people. It was the second mass shooting in the state and the third in the nation during the Easter holiday weekend.

The shootings in South Carolina and one in Pittsburgh, in which two minors were killed early Sunday, also left at least 31 people wounded.

No one was reported killed in the violence at Cara’s Lounge in Hampton County, roughly 80 miles (130 kilometers) west of Charleston, according to an email from South Carolina’s State Law Enforcement Division, which is investigating the shooting. A phone call to the nightclub was not answered.

In Pittsburgh, two male youths were killed and at least eight people wounded when shots were fired during a party at a short-term rental property. The “vast majority” of the hundreds of people at the party were underage, the city’s Police Chief Scott Schubert told reporters. The Allegheny County Medical Examiner’s Office identified the two victims as Jaiden Brown and Mathew Steffy-Ross, both 17. (AFP)
