Several families are homeless after a fire swept through three Bronx Park Avenue homes Sunday.

Fire officials say the fire started on the first floor at 374 Bronx Park Ave. and spread to two nearby homes. While firefighters were able to get the two-alarm fire under control within an hour, two firemen were treated for shoulder and back injuries. A police officer was also injured.

The Red Cross is helping displaced families and the cause of the blaze is under investigation.
