VIDEO: A nine-alarm fire tore through a Lower Mills neighborhood in Dorchester on Saturday, displacing 14 residents, according to Boston fire officials.
The Boston Fire Department said nine people, including seven firefighters, were treated and transported to a hospital by Boston Emergency Medical Services. The injuries are considered non-life-threatening.
Fire officials said crews responded at 4:45 p.m. to the area of 39 Old Morton St., which is near the Mattapan neighborhood line. Witnesses told WCVB and investigators that they heard a loud boom.
The fire started in a vacant home that was under construction. Upon arrival, firefighters found the home fully engulfed in flames, which eventually spread to seven adjacent homes.
