A shooting on Kraków’s Main Market Square killed six people on Saturday and wounded 15 more, a rare mass attack in modern Poland. Authorities identify the gunman as Michał Oksiński, 24, from Ostrowiec Świętokrzyski; he died in hospital on Monday morning after police shot and subdued him.

According to the National Prosecutor’s Office, Oksiński drove through the central square and nearby streets around 3 p.m., firing dozens of rounds. Two officers who stopped him were also wounded. Among the Kraków victims were Polish citizens and foreigners, including from Britain and Austria.

The same day, investigators found the bodies of the suspect’s parents and 21-year-old sister at the family home in Ostrowiec Świętokrzyski, with gunshot wounds. Prosecutors link both cases to the same perpetrator and opened probes for terrorist-character murder in Kraków and murder in Ostrowiec.

In the car and on the attacker, the inquiry says, were four firearms — two AR-15 rifles and two pistols — plus hundreds of rounds. Oksiński had held a gun permit since January 2026 and bought his first weapon in March, the official release states.

Motive remains unclear. The interior minister spoke of far-right leanings; prosecutors said it is too early to tie the attack to a political ideology, and the nationalist opposition publicly disputed such claims. Without a judicial finding, those lines stay allegations and political dispute, not established fact.

On Monday evening residents lit candles and held a silent march on Kraków’s square. Justice authorities said the investigation continues after the suspect’s death, including checks on whether anyone else aided or incited the attack.

In short: Poland faces a rare square shooting with six dead in Kraków and three bodies at the suspect’s home; any ideological cause is contested, and the case stays open.
