An intense fire that ripped through three townhouses on Joint Base Andrews, more commonly referred to as Andrews Air Force Base, displaced more than a dozen residents and injured one firefighter, authorities said.

The incident took place Thursday afternoon at 2098 Madison Avenue, a residential section on Andrews, said base spokesman Eric Sharman.

He said there were four homes in the area, and at least three were affected by the blaze.

The Associated Press reports that 17 people were displaced and have been relocated. Members of the Navy, Marines and Air Force, and their families, were affected, according to AP.

Prince George’s County firefighters were among those who helped battle the blaze. Mark Brady, a fire department spokesman, posted on Twitter that the townhouses were “involved with heavy fire.”

One firefighter suffered from smoke inhalation and no other injuries were reported, according to a base spokesman.

Officials believe the fire started in the back of one of the townhouses, reports AP. The cause of the fire remains under investigation.
