Part Of School Destroyed In Apparent Explosion

MINNEAPOLIS (CBS4) - Emergency responded to the scene of a building explosion at a school in Minneapolis.

Part of the Minnehaha Academy may have been destroyed as a result of a natural gas explosion, according to Minneapolis Fire Department.

CBS Minnesota reports one person has died and another is unaccounted for in the explosion and collapse. Nine others went to the hospital, three of whom are in critical condition, and four having suffered serious injuries.

Fire officials confirm no children were hurt in the incident.

Firefighters are working to extinguish a blaze caused by the explosion, and rescue any additional victims.

"We heard a man yell 'gas' and 'get out', and we saw one sprint down the street and one sprint into the building, kind of standing in the doorway, yelling it. About the time the man sprinting down the street got to the end down here there was a huge explosion," said Jack Mahler, a witness who was playing soccer nearby. "Smoke went up and knocked most of us back. It knocked me off my feet."

Minnesota Gov. Mark Dayton also issued a statement, saying the "state will provide any and all resources to aid first responders."
