KRAKÓW, Poland — A gunman drove into Kraków’s Main Market Square on Saturday afternoon and opened fire at random from his car, killing six people — and police later found three more bodies at his home, bringing the death toll to nine in one of the worst mass shootings in Poland in recent years.

The attack began at about 3 p.m. local time (9 a.m. ET), when the suspect drove into the historic square and started firing at pedestrians, Kraków police said, according to CNN. He stopped at multiple spots around the square, firing at each one.

Those killed in the square were four women and two men, including three Polish nationals and a British citizen; two others had not yet been identified. At least 16 people were wounded, including five foreign nationals and two police officers — two senior constables remained in “very critical condition” after suffering three gunshot wounds each and undergoing surgery.

The suspect, a 25-year-old Polish citizen from Ostrowiec Świętokrzyski, about 120 miles north of Kraków, was wearing military-style clothing and a bulletproof vest and used a military-type long gun, police said. He had a firearms permit, and many weapons and ammunition were found in his vehicle. He had no previous criminal record. The first patrol reached the scene 23 seconds after the attack was reported, and officers opened fire on the gunman three minutes later. He was shot and wounded, underwent multiple surgeries, and was in “stable but very critical condition,” a regional police spokesperson told Reuters.

Hours later, police searching the suspect’s home in Ostrowiec Świętokrzyski found the bodies of two women and a man. Prime Minister Donald Tusk said there were “strong indications” they were members of the gunman’s immediate family.

Interior Minister Marcin Kierwiński said investigators believe the attacker was fascinated by far-right ideologies and held “very radical” and “ultra-nationalistic” views — but stressed the picture is preliminary and the investigation continues. Defense Minister Władysław Kosiniak-Kamysz called the attack an “act of terror” and denied reports the suspect had served in the Polish military: “The man was not and is not a soldier in the Polish Armed Forces and has never had anything to do with the military.” Police said the suspect acted alone and denied reports of a second attacker. It was not immediately clear what the gunman’s motive was.

Kraków Mayor Łukasz Gibała declared a period of mourning in the city. Prime Minister Tusk headed to Kraków after the attack.
