Two teenagers have been shot at a high school in Arizona, but there is no more danger to the rest of the campus, police said.

A spokeswoman could not confirm whether the victims at Independence High School, in the Phoenix suburb of Glendale, were students. She did not discuss the conditions of the teenagers.

She did not say who fired the shots but said there is no longer an active shooter.

Numerous police and fire units descended on the school, and streets were closed to traffic in the residential area around the campus.

The school, founded in 1977, has more than 2,000 students.

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

The Glendale Union High School District said in a statement on its website that no-one can leave or enter the campus until police ensure the school's safety and lift a lockdown.
