At least four people were killed and nine others injured in the shooting at Apalachee High School in Winder, Georgia – about 50 miles outside of Atlanta, authorities said.

Apalachee High School reportedly received a phone threat warning that it would be one of five area schools shot up moments before the mass shooting unfolded, according to a report.

As a precaution, all schools in Barrow County have been placed on lockdown, the sheriff's office reported on Wednesday morning.
