The gunman who killed six people in Krakow's Main Market Square on Saturday has died in hospital, Polish police said early on Monday. The 24-year-old, who was shot by police minutes after opening fire, had been in hospital since the attack, Reuters reported.

The shooting began shortly before 15:00 local time on Saturday, when the man drove into the historic square and began firing randomly at people, initially from his car. Four women and two men were killed, including a British national and an Austrian woman, and 17 people were injured. Police said the attacker wore military-style clothing and used military weapons, CNN reported.

Far-right ideology investigated

Interior Minister Marcin Kierwinski said the shooter was fascinated by far-right ideologies and held "very radical views". Poland's prosecutor's office said it was "highly likely" the killings were carried out by the same person whose family members were found dead at his home.

The bodies of the suspect's mother, father and sister were found at his home in Ostrowiec Swietokrzyski, about 120 miles north-east of Krakow. Police have given no motive, and the attack is being investigated as a possible terror attack. Polish media named the suspect as Michal Oksinski.

A country in mourning

The attack shocked a country with exceptionally tight gun laws, where mass shootings are rare, and prompted national mourning and heightened security. The investigation continues into how the gunman obtained his weapons and whether anyone else was involved.
