Three killed in attack on St. Louis school, including the attacker

SARAJEVO, (Patria) - Three people were killed today in an armed attack at a high school in St. Louis, USA, police officials said.

Police Commissioner Michael Sack said that among the dead were one adult, one girl, and the person who fired the shots.

The attack occurred shortly after nine o'clock local time at Central Visual and Performing Arts High School, prompting students to barricade themselves in classrooms, huddle together, jump out of windows, and flee the school building to take cover.

Within minutes, dozens of police vehicles appeared around the school.

Earlier, the school announced that six people were injured in these events, and that police had "quickly stopped" the attacker and taken him into custody.

The US FBI said there was no longer an "immediate threat" at the school.
