At least 12 people, including some elderly and children, were injured Wednesday night when a duplex exploded and shook a Dorchester neighborhood after a possible gas leak, authorities said.
The blast at 27 Hansborough St. erupted into a three-alarm fire that left two elderly residents with critical injuries and numerous families evacuated from their nearby homes, authorities said.
Steve MacDonald, a Fire Department spokesman, said nine people inside the home were injured and three others who were outside suffered wounds that may have been caused by flying debris or shattered glass.
Mike Bosse, a deputy superintendent with Boston Emergency Medical Services, said two of those inside the home were elderly people who were critically injured and had significant burns. They were taken to Brigham and Women’s Hospital, but there was no information on their conditions early Thursday morning.
