Four firefighters and three civilians were injured Wednesday evening when a fire truck responding to a blaze slammed into a car, officials in Anne Arundel County said.

The crash took place about 6:45 p.m. on Ritchie Highway at Route 648 in Glen Burnie.

The rescue unit was headed to help fight a fire at a senior living facility in the 7900 block of Benesch Circle.

The firefighters were about three miles away from the site of the blaze when the accident occurred.

All seven people involved in the crash sustained minor injuries and were transported to area hospitals for treatment, according to officials. None of the injuries were life-threatening.

The fire caused no fatalities, although one man had to be rescued from the multi-story building, officials said. He was taken to a burn center for treatment.

The cause of the fire remains under investigation.
