Three Baltimore firefighters were seriously injured battling a blaze in a vacant home early Monday and crews were working to rescue a fourth firefighter trapped inside, officials said.

Baltimore City Fire Department Chief Niles R. Ford tweeted that firefighters were responding to a burning three-story rowhouse when a partial collapse trapped four members inside.

One firefighter was immediately pulled from the vacant house, the chief said. Crews cleared piles of debris and found two other trapped firefighters within an hour of the fire, he said.
