4 dead in US high school shooting

At least four people were killed in a shooting at a US high school in the state of Georgia on Wednesday, CNN reported.

In addition to the four killed, dozens of people were injured in the shooting at Apalachee High School in Winder, Georgia, CNN said, citing unnamed law enforcement officers briefed on the incident. Not all injuries appeared to be gunshot wounds, but rather also people hurt while fleeing.

One suspect was in custody, the Barrow County Sheriff's Office said in a statement.

"What we see behind us is an evil thing today," Sheriff Jud Smith said during a brief news conference on school grounds. Smith would not confirm that people were killed, saying only there were "multiple injuries" in the shooting.

The incident appeared to be under control and students were being released at midday, a Barrow County Schools spokesperson said.

ABC News quoted a witness, student Sergio Caldera, as saying he was in chemistry class when he heard gunshots.
