Poland opens terror investigation after six killed in Kraków square attack

Polish authorities have declared two days of national mourning and launched a counter-terrorism investigation following an attack on the Rynek Główny main square in Kraków that left six people dead and 15 wounded.

The incident occurred around 15:00 local time when a vehicle drove across the crowded market square as a shooter opened fire on bystanders. Eyewitnesses described widespread panic on the square as tourists and locals attempted to assist the injured before emergency services cordoned off the area.

Poland's national prosecutorial office confirmed that the assault is being treated as a terrorist offense under national law. Authorities have heightened security measures across the country while forensic and law enforcement investigations into the attack continue.
