KRAKOW — Poland is in deep mourning following a horrific mass shooting that transformed Krakow's historic Main Market Square into a scene of devastation. Prime Minister Donald Tusk has officially classified the rampage as an act of terrorism as investigators uncover a grim web of violence stretching from the tourist hub to the suspect's family home.

​The attack unfolded just before 3:00 p.m. on Saturday, when a 24-year-old Polish national, identified as Michal O., drove a black Subaru directly into the crowded pedestrian zone. Clad in military-style tactical gear and a bulletproof vest, the gunman opened fire indiscriminately from the driver’s side window using an AR-15-style rifle, targeting tourists and weekend crowds enjoying the square’s outdoor spaces.

​Emergency responders flooded the area within minutes, tracking the vehicle as the gunman sped south. The rampage was brought to a bloody halt roughly a kilometre away after a fierce exchange of gunfire with police. Two responding officers were injured—one critically after being shot multiple times—before another officer returned fire, incapacitating the attacker. The suspect is currently recovering in a hospital under heavy police guard.

​Escalating Horror and Family Discovery

​While six people—four women and two men, including a British national—were killed in the market square, the investigation took a darker turn hours later. When authorities searched the suspect's family residence in Ostrowiec Świętokrzyski, about 150 kilometres away, they discovered the bodies of three additional family members: the gunman's mother, father, and sister. Investigators are treating the triple homicide as directly linked to the massacre.

​More than a dozen others sustained injuries during the drive-by attack, including foreign nationals from Portugal and the wounded police officers.

​Radical Ideology and National Response

​Interior Minister Marcin Kierwiński stated that early evidence, digital footprints, and materials recovered from the scene indicate the shooter held "very radical views" and was heavily influenced by right wing objections to the shift of the country to the left.

​In response to the tragedy, President Karol Nawrocki declared a period of national mourning, while local officials in Kraków established a city-wide mourning period extending through Wednesday. Major cities, including Warsaw, have hastily moved to implement heightened security and vehicle barriers around historic old towns.

​Despite the profound shock rippling across the nation, Kraków’s leadership has vowed resilience. "The square will belong to us again," Mayor Łukasz Gibała pledged in a public statement, emphasizing that the city will honor the victims while refusing to cede its public spaces to terror.
