Police and officials say six people have been killed and three wounded in a shooting in a hospital in the eastern Czech Republic. The apparent suspect later died of a self-inflicted gunshot as police approached his car.

The shooting happened Tuesday morning in the University hospital in the city of Ostrava.

People have been evacuated from the hospital and security has been increased across the country. 

According to the Associated Press, Prime Minister Andrej Babis said the shooting happened in a waiting room. The shooter opened fire at people's heads at close range.

Police initially posted a photo of a man who they said was a suspect, but later said he was an important witness.

"We are currently strengthening the supervision of selected soft targets across the Czech Republic. We ask the public for patience and thoughtfulness," Czech police tweeted.
