A 24-year-old man suspected of killing six people during a weekend shooting in a crowded Kraków market square has died from injuries sustained during a shootout with law enforcement, according to Polish authorities early Monday.

Investigators launched a terrorism inquiry into the incident, noting that the suspect, identified by local media as Michal O., may have been motivated by far-right beliefs. Following the exchange of gunfire with responding officers, he had remained in critical condition at a hospital before succumbing to his wounds.

Additional information regarding the ongoing investigation is anticipated as developments emerge.
