On Monday, the Clearwater County Sheriff’s Office said dispatch received a call of an explosion and fire at a storage unit north of Bagley around 12:30 p.m.

When deputies and police arrived at the scene, they found a man and five children ranging in age from 6 to 14 suffering from burns from the explosion.

The sheriff’s office said they believe a propane tank in the metal storage unit leaked, causing the explosion when the doors opened and the man lit a cigarette.

The sheriff’s office said people in the area helped the six victims until first responders arrived, and all six injured were taken by ambulance to local hospitals.

The sheriff’s office says they do not know the conditions of the victims.

The Minnesota State Fire Marshal’s Office is investigating the incident.
