The ferocity of the flames compelled firefighters to adopt a defensive strategy, tackling the fire from the building’s exterior.

During the operation, a firefighter fell through the floor of one of the structures but managed to escape and seek assistance. He was transported to Stroger Hospital and is anticipated to recover, as confirmed by CFD officials.

Another civilian was also treated for minor injuries that were unrelated to the fire.

Chicago fire officials said more firefighters were called to the scene due to the cold weather. At one point, one of the hydrants froze. That was just one of many challenges these firefighter faced in battling the flames

CFD has not yet released a cause for the fire. At least two buildings are now a complete loss.
