EAST BOSTON (WHDH) - An East Boston duplex went up in flames on Sunday, displacing at least 15 people.

Residents say two strangers made their way through the building alerting people to the fire.
Fire officials say the flames spread from the third floor up through the roof of the building. Firefighters were ordered off the roof because it was so unstable.

Families returned to the home hours after the blaze to collect whatever was left of their belongings.
The Red Cross is assisting the displaced families find a place to stay.
There were no reported injuries. Officials estimate there was about $500,000 worth of damage done to the home.
