3 Alarm Fire In Cambridge

CAMBRIDGE, MA — Firefighters have put out the bulk of the flames that prompted a three-alarm fire at a wood-frame duplex on Putnam Avenue.

An alert came in to officials just before 8 a.m. reporting a building on fire at 511-513 Putnam Avenue. When firefighters arrived they were met with fire in the building's attic and called a second alarm. A little while later, with flames pouring out of the roof, officials made the call to upgrade it to a third alarm.

It's not yet clear if anyone was home at the time of the fire or if there are any injuries.

Watertown and other neighboring fire departments were called in for help.

Folks took to Twitter to report they could see the smoke from across the river:
