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.
It was unclear how the shooter died.
Captain Richard Meulenberg said the medical complex was a “catastrophic scene”.
“Officers are currently going through every room in the building checking for additional threats,” police said in a Facebook post just before 6pm.
