Shortly before 1100 local time (1600 UTC) on 9 February 2021, a 67-year-old local man opened fire at the Allina health clinic in the town of Buffalo, Minnesota, located approximately 40 mi (65 km) northwest of the city of Minneapolis. Approximately 30 minutes after the shooting, at least one explosive device reportedly detonated inside the facility as officials were searching for additional victims. Five people were shot and wounded; one of the victims later succumbed to their wounds. Three others remain in critical but stable condition at a hospital. Police officers detained the gunman at the scene. The detainee had been angry about health care services that he received and might have been treated at the facility in the past. The man has a criminal history, most of which was due to driving while intoxicated. Law enforcement officials are currently conducting an investigation to establish a definitive motive for the attack.
