Three Baltimore firefighters were injured fighting fires that broke out in two different vacant properties early Saturday, though their injuries were described as minor.

Both fires reached a single alarm but were under control before they could spread to other buildings, and their causes are under investigation, fire officials said.

Two firefighters were injured fighting a rowhome fire in the 500 block of Cumberland Street in the Druid Heights neighborhood, while one firefighter was injured in a fire in the 2200 block of West Pratt Street in the Carrollton Ridge neighborhood.
