A 42-year-old gunman killed six people on Tuesday at a hospital waiting room in the eastern Czech city of Ostrava before fleeing and fatally shooting himself in the head, police said.
It was the worst shooting in the Czech Republic, where gun crime is relatively rare, since a man shot eight people dead and then killed himself at a restaurant in Uhersky Brod in 2015.
It was unclear what motivated the shooting, which happened in the early morning at the outpatient clinic of the University Hospital in Ostrava, a city of 290,000 people 350 km (217 miles) east of the capital Prague and near the border with Poland.Prime Minister Andrej Babis told reporters it was an "individual act".
