A gunman suspected of killing six people in Krakow has died in hospital, Polish police say. The 24-year-old, who ministers said was apparently inspired by "far-right ideologies", was injured after opening fire in central Krakow, the second largest city in Poland, on Saturday. Armed officers raced to the scene and engaged in a gunfight with the suspect, who was shot within three minutes of the attack beginning, preventing a further massacre, officials said.
