A gunman killed six people and injured more than a dozen others in a shooting in central Krakow, Poland, on Saturday afternoon, authorities said. A British citizen was among the four women and two men killed when the attacker drove onto Main Market Square, a popular tourist attraction in Poland's second-largest city, and began firing at people. Three of the dead were Polish and two have not been identified.

The 25-year-old Polish suspect, described by Poland's interior minister as having been fascinated by far-right ideologies and holding ultra-nationalist views, was injured in a shootout with police and taken to hospital for surgery. One police officer was critically injured in the firefight and a second suffered less serious injuries. Poland's prime minister called the officers heroes and said they saved many lives.

Polish Prime Minister Donald Tusk said three additional bodies were found during a search of the suspect's home about 125 miles from Krakow. Tusk said there were strong indications the two women and one man were the suspect's immediate family members. More weapons and ammunition were found in a car belonging to the suspect, who wore military tactical gear during the attack but was not a member of the Polish armed forces.

Of the 15 people injured in the attack, five were foreign nationals from Britain, Austria, Russia, Germany, and Portugal. The attack began shortly before 3 p.m. local time and lasted about three minutes as the attacker drove through the historic city center, firing at shops, a tram, and pedestrians before crashing and engaging police. Krakow has declared a period of mourning through November 11.
