A two-alarm fire in a south Minneapolis house displaced residents Friday afternoon but didn’t cause any injuries.

The Minneapolis Fire Department said the cause of the fire, which displaced up to 20 residents, is under investigation.

The fire engulfed the three-story house around 1 p.m. Friday on the 2000 block of Fifth Av. S. in Minneapolis.

The fire department, posting to its Twitter account, reported “heavy fire” on the third floor before calling a second alarm.
