Overview
- Boston firefighters, who responded around 6 p.m. Sunday, found heavy flames on the back porches of a triple-decker on Princeton Street in East Boston.
- The fire extended to three nearby buildings, prompting a fourth alarm that brought more crews to the scene.
- Teams deployed multiple hose lines to contain the blaze and keep it from jumping to more structures.
- Authorities described the situation as developing and said details on injuries and the cause were not yet available.
- Rear porches and open attic paths on wood-frame triple-deckers can channel flames upward and across closely spaced homes, which helps explain the rapid spread and large response.
