A 25-year-old gunman opened fire with an automatic weapon in
historic Main Market Square, killing six people and wounding 16 others.
Police later found three deceased family members at the suspect's home.
Prime Minister Donald Tusk declared two days of national mourning, calling the attack an unprecedented act of terrorism.
The casualties inside the crowded tourist hub include three Polish citizens, one British national, and two individuals who are still being identified.
Polish authorities have implemented sweeping security updates and declared a period of national mourning after a gunman driven by far-right extremism killed six people in Krakow's historic center before being shot and apprehended by police.
Polish Prime Minister Donald Tusk condemned the mass shooting, explicitly labeling the assault as a clear departure from domestic safety norms.
"Until now in Poland we haven't had such drastic cases of terrorism," Tusk told reporters during an emergency press conference in Krakow, adding, "That's what we have to call this cruel attack on people's lives."
Interior Minister Marcin Kierwinski stated that early evidence points directly to intense political radicalization as the primary driving force behind the assault.
"Everything points to the fact that the shooter was influenced by far-right ideology, a matter that will also be subject to investigation," Kierwinski noted during a news briefing, later clarifying that the suspect possessed "very radical" and "ultranationalistic" beliefs.
The primary attack unfolded on Saturday afternoon when the gunman drove a vehicle directly onto Krakow’s prominent Main Market Square, stopping at multiple locations to fire randomly into crowds with an automatic weapon.
Police Chief Marek Boron confirmed that the six fatalities inside the square consisted of four women and two men. Among the sixteen hospitalized survivors are five foreign nationals originating from Austria, Germany, Portugal, Russia, and the United Kingdom.
Following the shooter's capture, counter-terrorism units raided his home located approximately 150 kilometers away.
Prime Minister Tusk confirmed that investigators recovered the bodies of two women and one man at the property, stating there is "much to suggest that they are members of the immediate family."
The 25-year-old perpetrator was shot and wounded by responding police officers before being taken into custody, and law enforcement later recovered a cache of multiple weapons inside the car he used during the attack.
Internal Security Agency investigators revealed that the suspect exhibited a deep fascination with far-right extremist frameworks, radical online content, and ultranationalist political dogmas.
The suspect's primary residence is located in Ostrowiec Swietokrzyski, a city situated roughly 93 miles northeast of the Krakow crime scene where the family members were discovered dead.
The tragedy has severely shaken a nation that has historically viewed itself as insulated from the types of extremist mass casualty incidents seen in Western European neighboring countries.
This unprecedented mass shooting follows a separate string of school stabbings in October, which intelligence officials previously attributed to the digital consumption of violent extremist materials.
While the formal national mourning period is observed on Sunday and Monday, municipal officials in Krakow have extended local protocols, keeping the city in a formal state of mourning until November 11.
