BOSTON (CBS) -- One firefighter and four residents were injured in a fire at a multi-family home Tuesday afternoon, the Boston Fire Department said.
The fire chief said 21 people have been displaced as a result of the Havre Street blaze in East Boston.
At one point, smoke and flames could be seen coming out of the roof.
A mom and three children who inhaled smoke were taken to the hospital and a firefighter suffered minor burns.
Firefighters started working against the flames on the roof and from within the 3-story, 6-unit apartment building around 12:30 p.m.
Within an hour they were called off the roof and third floor.
The fire department also said they were worried the chimney might collapse because the roof area around it has burned away.
Witnesses say the fire started on the third floor and spread up to the attic and down to the second floor.
The fire was knocked down just after 2:30 p.m. Crews stayed on scene to watch for hot spots.
It is not clear what started the fire, the department has not released any more information at this time.
