Four people have been killed in a shooting spree at a hospital in Tulsa, Oklahoma, police say.
Law enforcement officials confirmed that the suspected shooter was also dead.
Officers said they were still working to clear the campus of the St Francis Hospital, where earlier there were reports of a man with a rifle.
Officials added that multiple injuries had also been confirmed.
Speaking at a press conference on Wednesday, Deputy Police Chief Eric Dalgleish said: “Right now we have four civilians that are dead, and one shooter that is dead.”
He said the shooter, who has not yet been identified, sustained fatal gunshot wounds which were believed to have been self-inflicted.
The suspect “had one long gun and one hand gun on the scene at the time”, he said.
No information was available about a possible motivation for the attack.
