A gunman has been shot dead after killing three people at a hospital campus in Oklahoma.
Tulsa Police also said there had been “multiple injuries” in the shooting at the St Francis hospital campus in Tulsa, and officers were still in the process of clearing the building.
Captain Richard Meulenberg told ABC that police were phoned about a man with a rifle on the second floor of the Natalie Medical Building, which “turned into an active shooter situation”.
He said that when officers arrived on the scene, “they found a few people have been shot. A couple were dead at that point.”
“We also found who we believed to be the shooter and still believe to be the shooter, because he had a long rifle and a
pistol with him,” he said.
It was unclear how he died.
Mr Meulenberg said the medical complex was a “catastrophic scene”.

In a post on Facebook just before 6pm (12am UK time), police said officers were “going through every room in the building checking for additional threats”.
St Francis Health System locked down its campus on Wednesday afternoon because of the situation at the Natalie Medical Building.
The building is the site of an outpatient surgery centre and a breast health centre.
First responders were seen wheeling someone on a stretcher away from the building in aerial footage from a TV helicopter.
