A day after a deadly shooting in central Krakow left six people dead and 15 others injured, Polish authorities say three bodies believed to be the suspect's close family members were found inside his home. The 25-year-old attacker allegedly drove through Krakow's Main Square, opening fire at multiple locations before being shot and wounded by police. Poland's Defence Minister has described the incident as an "act of terror." A UK citizen was among those killed in the attack.
