Shocking footage shows students at Apalachee High School in northern Georgia standing in a circle in prayer after they were evacuated following a deadly shooting.

More than 40 students were photographed holding hands in a ring on the school’s football field on Wednesday.

According to footage from WSB-TV, the students had their heads bowed and appeared to be praying.

Other prayer circles also sprang up among students on the field.

A gunman opened fire at the school in Winder, about an hour’s drive northeast of Atlanta, around 10:30 a.m., killing at least four people and wounding 30, CNN reported.

It is unclear whether all of the injuries were caused by gunfire.

According to the Georgia Bureau of Investigation, the shooter had been “neutralized.”

Reports say the shooter is a school-goer, but it is not clear whether the attacker attended the same school.

Classes had been in session for over a month when the deadly attack occurred.

About an hour after the shooting, students were evacuated from the school and sent home.

Sergio Caldera, a 17-year-old senior at the school, told ABC News he was studying chemistry when they heard a volley of gunfire.

“My teacher goes to open the door to see what’s going on. Another teacher comes running in and tells her to close the door because there’s an active shooter,” said Caldera, who recalled someone banging on their door and yelling, “Open up!”

Then the knocking stopped and the class heard gunshots and screams.
