A fire broke out early Tuesday morning at a three-story building on Meridian Street in East Boston.
Crews were on scene of the fire at around 2:30 a.m. Tuesday, and firefighters were able to knock down heavy fire in the basement. There was heavy smoke, limiting visibility.
The building — which was unoccupied at the time of the fire — appeared to be home to multiple businesses on its first floor, including a restaurant and a salon.
The fire was knocked down by around 4:30 a.m. No one was reported hurt.
An added challenge for firefighters was the overnight closure of the Ted Williams Tunnel.
The cause of the fire was the subject of an investigation by Boston Fire Department.
Crews were to remain on scene to check for hot spots.
