A fire ripped through a store in San Francisco's Mission District on Thursday, spitting thick gray smoke high into the air and injuring at least four people, officials said.
The blaze broke out in an unoccupied store between 22nd and 23rd Street on Thursday afternoon, and spread through several floors of the building, according to a spokeswoman for the San Francisco Fire Department.
At least four people were hurt, and one had to be hospitalized for injuries that might have been related to smoke inhalation, the spokeswoman said.
Firefighters on scene were forced to battle the blaze from the outside, as the fire was too strong for rescue crews to enter the building, according to the spokeswoman.
The spokeswoman said the fire erupted in the 2600 block of Mission Street, at the address of Big House Inc., a retail store.
