CHICAGO -- Three families have been displaced after a fire in an apartment in the city's Bronzeville neighborhood

The fire broke out around 1 a.m. Tuesday near 45th and Drexel.

A mother and her six children were rescued by two neighbors from inside a unit on the first floor. Residents say their heater started the fire.

Two men who lived across the street say they saw the flames and ran to help rescue them.

Paramedics treated one of the rescuers for burns on his chest.

Several other residents, including a pregnant woman, went to the hospital to be checked out. They are expected to be OK.

The Red Cross is helping the displaced families.
