There was an explosion in downtown Bozeman Montana on Thursday morning. The explosion leveled three buildings and the three block surrounding area had to be evacuated.

Reports indicate the explosion happened at about 8:15 a.m. in the 200 block of Main Street.

Crews were working to extinguish a fire caused by the explosion.

Boodles restaurant and bar were destroyed, KBZK-TV reported. A police dispatcher said the adjacent Rockin R bar was also destroyed. Police evacuated the two blocks surrounding the businesses, housed in brick buildings. The fire crews had trouble getting to the fires because there was a snow storm during the incident.

Jason Shrauger with the Gallatin County Disaster and Emergency Services said it was unknown what caused the explosion or if there were any injuries.
