A fire in a three-story brick apartment building in the Albany Park neighborhood early Sunday morning displaced 27 people, authorities said.
Fire engines, trucks and ambulances jammed the blocks surrounding the building, in the 4800 block of North Lawndale Avenue, as crews worked to extinguish the blaze.
The Chicago Transit Authority provided warming buses on Lawrence Avenue for displaced residents.
A spokesman for the fire department said the fire started on the building's back porches.
Nobody was injured. The American Red Cross of Greater Chicago was giving help to 27 people, including 12 chidlren, who were displaced by the fire, a spokeswoman said. A shelter has been set up, but the number of people who will be given shelter Sunday night was not immediately known.
