MINNEAPOLIS - Authorities say at least 13 people are hospitalized following a building explosion and fire in Minneapolis Wednesday morning.

The reported address of the incident is 514 Cedar Avenue South. Robert Ball of Hennepin County EMS tells KARE 11 that 13 people have been injured and rushed to a number of local hospitals. He describes the injuries as ranging from burns to trauma suffered while falling or jumping from windows.

MPR reports that 6 of the victims are currently listed in critical condition.

A check on Google Maps indicates that the main floor of the structure houses a business called the Otanga Grocery, with the upper two floors consisting of apartments.

Firefighters are swarming the scene after the call was elevated to three alarms. Unconfirmed reports say the second and third floors of the structure have collapsed. The frigid weather conditions are making things both challenging and dangerous for crews trying to put down the blaze.

KARE 11 has multiple crews on the scene and will have the latest information as the story develops.
