Glendale - Two students were shot and killed on Friday at a school in a Phoenix suburb but the danger at the campus was over, police said.
Glendale Officer Tracey Breeden said both 15-year-olds were shot once and a weapon was found near the bodies.
She did not say who fired the shots and had no information on the relationship between the girls, who died at the scene.
Breeden told parents awaiting word on their kids that "your children are safe".
No one can leave or enter the campus of more than 2 000 students until police ensure the school's safety and lift the lockdown, Glendale Union High School District said in a statement on its website.
