Poland mourns Krakow shooting victims as terrorism probe launched

Poland began two days of ​national mourning on Sunday and police bolstered security after six people were killed in a mass shooting in Krakow's historic main square that the government said ‌was likely inspired by far-right ideology.

Polish National Prosecutor's Office said on social media it had "launched an investigation today into yesterday's attack in Krakow," adding that the incident was being investigated as a terrorist offense.

Sixteen people were wounded in the attack, including two police officers and the suspected gunman, ​a 24-year-old Polish man who remained in a critical condition in hospital, local authorities said.

Krakow's old town is a UNESCO World Heritage Site that ​attracts visitors from around the globe, and several foreigners were among the casualties. One of the people who died was identified ⁠as a British citizen, while five foreign nationals from Austria, Germany, Portugal, Russia and Britain were among the wounded.

In the ​suspect's home town, Ostrowiec Swietokrzyski, about 200 km (124 miles) north of Krakow, police later found the bodies of his parents and sister at his home.

Prosecutor's Office ​spokesperson Daniel Prokopowicz said it was "highly likely" that the killings in Ostrowiec Swietokrzyski and Krakow were carried out by the same person, but that investigations were ongoing.

The bodies had gunshot wounds, and seven firearms and a "significant" quantity of ammunition were recovered from the property, Prokopowicz added.
