Fire officials say 20 people were left homeless after a fire ripped through a duplex in suburban Boston.
Acting Fire Chief Robert Houghton tells The Boston Globe that at least 12 people were inside the Chelsea building when the fire broke out just after 4:30 p.m. Tuesday.
Firefighters extinguished the flames in about three hours. Houghton says no serious injuries were reported.
The state fire marshal's office is investigating the cause of the blaze.
