Two teenage girls have been killed in a shooting at a high school in Arizona.

Police said both victims were 15-year-old girls and were shot once each in the incident at Independence High School in Glendale, Phoenix.

A spokeswoman said authorities are not searching for any suspects and a weapon was found near the bodies.

She did not have any information on the relationship between the girls, who died at the scene near an administration building.

Earlier, police and fire units descended on the school and surrounding streets were closed to traffic as police put the campus on lockdown.

Dozens of worried parents gathered at a nearby convenience store for word about their children.
