Authorities say two Los Angeles firefighters were hospitalized for injuries suffered when a floor gave way in a blaze at a vacant house in Koreatown.
Department spokesman Brian Humphrey says one of the firefighters suffered second-degree burns over 10 percent of his body and small burns on his hands.
The other was treated for a sprained ankle and released.
Humphrey says the firefighters were hurt early Wednesday when a section of the ground floor of the two-story residence collapsed.
It took more than 100 firefighters about 90 minutes to knock the flames down.
