MILWAUKEE --
Two firefighters are recovering after being injured while trying to put out an overnight fire.
The fire broke out at an apartment building in the 500 block of South 69th Street at 1 a.m. Saturday.
Firefighters said the three-story apartment building was filled with smoke.
They said the fire likely started on the first floor and then spread.
Firefighters said that a 23-year-old woman living in the apartment suffered some burns and smoke inhalation. She's still being treated in a hospital.
The two injured firefighters are a 32-year-old man with 21 years of service and a female firefighter with 20 years of service.
Their identities have not been released but commanders said that the man suffered second-degree burns to his face. The female firefighter also suffered facial burns.
Investigators said they aren't sure how the pair was injured.
The cause of the fire is still unknown but fire crews said it does not appear to be suspicious.
The damage is estimated at $10,000.
