A gunman suspected of carrying out a shooting attack in central Krakow, Poland, on Saturday, which left six people dead and fifteen injured, has died in hospital. The 24-year-old suspect is believed to have been inspired by far-right ideologies and was found to have a firearms permit, according to Polish officials. Three family members of the suspect - his 53-year-old father, 52-year-old mother, and 21-year-old sister - were also found dead at their home. The attack took place in Krakow's busy Main Market Square shortly before 15:00 local time (14:00 GMT). The victims included four Polish nationals, a British national, and an Austrian woman. Two police officers were among those injured, along with five foreigners from Austria, Germany, Portugal, and Russia. The Prime Minister of Poland, Donald Tusk, declared the country would enter two days of national mourning in the wake of the attack, which he described as "drastic cases of terrorism." The shooting has left the city in shock, with witnesses describing their panic and confusion as the attack unfolded. In response to the tragedy, UK Prime Minister Andy Burnham expressed his condolences and solidarity with the people of Poland.
