A pair of fires ripped through homes in Dorchester and Cambridge Wednesday night causing injuries and displacing scores of people.


In Boston, fire crews were called to 27 Hansborough St. at about 9:20 p.m. for a report of an explosion and a partial building collapse, according to the fire department. When firefighters arrived they had flames shooting from the basement and upper floors. Two sides of the home collapsed and the door was blown across the street, the fire department said.


Twelve people were injured in the explosion and three-alarm fire. Two of the injuries were serious and no firefighters were injured.


Less than three hours later, fire crews in Cambridge were called to 884 Massachusetts Ave. for a report of a fire. That fire, at an apartment building, reached six alarms. About 100 residents were evacuated to a nearby senior center and were being assisted by the American Red Cross of Massachusetts. There were no reports of injuries.


The causes of both fires are under investigation.
