Two people were pulled from the rubble of a three-unit apartment building that collapsed following an explosion on Chicago’s South Side on November 23, fire officials said.

The two victims are now in serious condition in hospital.

The two people, one of them described as an elderly woman, were believed to be the only ones inside at the time of the explosion at the three-story building at East 58th Street and South Calumet Avenue, about a block from Washington Park, the fire department said.

A dog was also rescued alive, fire officials said.
