At least four people were killed and about 30 others injured in a shooting at Apalachee High School in northern Georgia on Wednesday morning, according to a report.

A suspect, who is a student, is in custody, the sources said.

“I have deployed all available state resources to respond to the incident at Apalachee High School and I urge all Georgians to join my family in praying for the safety of those in our classrooms, both in Barrow County and across the state,” said Georgia Governor Brian Kemp.
