A five-alarm fire tore through a home in the outskirts of Boston early Wednesday, reportedly leaving six people injured, including two firefighters. 

The blaze erupted on all three floors of a duplex in Chelsea, and first responders received reports of multiple people trapped inside, Chelsea Fire Chief Leonard Albanese told Boston 25 News. 

"A very labor-intensive fire," he said. "The entire rear of the structure was burning on all three floors. The porches are gone. And all companies worked aggressively to contain this to the building of origin."
