A gunman suspected of killing six people in central Krakow and his parents and sister at their home has died in hospital, Polish police say.

Attack in Main Market Square

The 24-year-old was injured after opening fire in central Krakow, the second largest city in Poland, on Saturday, and died early on Monday morning, police said. Armed officers raced to the scene and engaged in a gunfight with the suspect, who was shot within three minutes of the attack beginning, preventing a further massacre, officials said.

Four firearms were found in the gunman’s car, including two AR-15 rifles and two handguns, along with several hundred rounds of ammunition. Authorities also seized at least four phones from his car and person, and electronic equipment from his home.

Victims and Response

Six people—four women and two men—are confirmed to have been killed in the attack. Four victims are Polish, while a British national and an Austrian woman were also killed. Sixteen people, including five foreigners, two police officers and the attacker, were taken to hospital. The interior ministry later said they were from Austria, Britain, Germany, Portugal and Russia.

Poland’s Prime Minister Donald Tusk said three bodies—two women and one man—were found at the gunman’s house when it was searched after the attack. On Sunday, Polish police confirmed those three victims had been identified as the alleged gunman’s 53-year-old father, 52-year-old mother and 21-year-old sister.

Medical and Political Reactions

Two surgeons who were eating near the Main Market Square when the gunman opened fire rushed to the scene to treat both the attacker and the two injured police officers. Professor Michal Pędziwiatr told the BBC that his colleague, Dr Mateusz Wierdak, used his hand to stem the bleeding from the most severely injured policeman, allowing time for an ambulance to arrive.

On Sunday it was reported that both injured officers had emerged from comas. Witnesses described panic and confusion as the attack unfolded. Ruby Catherine Warren, from London, heard gunfire and “yelled at my friends to run and we all sprinted for our lives.” Tom Brook, from West Yorkshire, was inside a McDonald’s near the square when he heard “multiple gunshots and saw people running for cover.”

Poland declared two days of national mourning in the wake of the shooting. Tusk said the attack should be called “terrorism.” UK Prime Minister Andy Burnham said he was “shocked and saddened by the appalling shooting in Kraków” and expressed solidarity with Poland.

Main Market Square reopened on Sunday evening after a security cordon was lifted. The attack’s site became a place of commemoration as many people laid candles and flowers. The St. Mary’s Trumpet Call, the melody played at Krakow’s Main Square every hour, stopped in honor of the victims for the first time since World War II.
