MINNEAPOLIS (WCCO) – Authorities are investigating after a home in north Minneapolis and a home in south Minneapolis were each damaged by fire overnight.

Fire crews responded to fire early Saturday morning on the 3300 block of Third Avenue South. Authorities at the scene found that the house was vacant. There were flames shooting through the front porch and first floor of the home. Nobody was injured in the fire.

Crews also responded to a fire on 27th Avenue North in Minneapolis. That fire started at around midnight on the upper level of a duplex.

Two adults and four children escaped the house safely and are now being assisted by the American Red Cross.

Minneapolis Fire Department officials said the cause of both fires is still under investigation at this time.
