BOSTON (AP) — Firefighters were struggling to put down a large fire that jumped from one building to another across a densely-populated neighborhood in Cambridge, Massachusetts, on Saturday. The fire was initially reported as a 9-alarm blaze, but a 10th alarm went out on Saturday afternoon, the Cambridge Police tweeted. Authorities said Saturday evening that two police officers and one firefighter were hurt but that no residents had been injured. #WBZ pic.twitter.com/NfDXkSV69g — Brad Tatum (@BradTatum) December 3, 2016

Cambridge police spokesman Jeremy Warnick says there have been some injuries reported but none of them are serious. He says the city has opened up a nearby youth center for families displaced from their homes. Fire crews were called in from surrounding cities and towns to help after the first calls came about 2 p.m. Saturday. Some witnesses said the fire started at a residential building undergoing renovations. A large plume of smoke was visible for miles as heavy flames engulfed multi-family residential buildings, including a former church that had been converted to condos, and several automobiles. 10th Alarm struck; 7-8 buildings involved — Cambridge Local 30 (@CFD_Local30) December 3, 2016
