Poland launches terror investigation following fatal Kraków shooting

Polish authorities have formally opened a counter-terrorism investigation and declared two days of national mourning after a attack in Kraków left six people dead and 15 wounded.

The incident began around 15:00 local time on Saturday when a vehicle entered Rynek Główny, Kraków's central market square, and a shooter opened fire on bystanders. Eyewitnesses described moments of panic as crowds fled the cobblestone plaza, while several bystanders remained behind to provide emergency first aid to the injured before medical teams arrived.

Poland's national prosecutorial office confirmed Sunday that the assault is being treated as a terrorist offense under national law. Security has been heightened across the country as forensic teams and law enforcement agencies continue their investigation into the attack.
