MINNEAPOLIS - Minneapolis fire officials say several people were hospitalized for minor injuries following a three-alarm fire at an apartment building in the Whittier neighborhood of Minneapolis.

Firefighters were dispatched to the 2445 block of 1st Ave. S. at 3:40 a.m. Wednesday, and found heavy fire jumping from the front of the building upon arrival. Crews immediately laid fire lines and began searching for trapped residents. A second alarm was called at 3:58 a.m., and eventually a third for additional manpower.

All residents were able to escape the blaze, but several were transported to a local hospital for minor injuries and smoke inhalation. The fire was brought under control about 5 a.m.

Investigators were quickly able to pinpoint the cause of the fire as an unattended BBQ on a second floor balcony. It has been ruled accidental.

According to Minneapolis Fire Department tweets, some residents were being assessed by paramedics for smoke inhalation. The Red Cross was called in to assist at least 10 adults who were displaced by the fire.

No firefighters were injured. The cause of the fire remains under investigation.
