Authorities say three people have been hurt after a series of gas explosions inside a Winthrop home sparked a two-alarm fire.
Firefighters responded after the explosions were reported by neighbors just after 8 a.m. Thursday.
The explosions blew the home's front door off, pushed windows out of their frames and cracked the side of the house.
Neighbors said their own homes shook from the blasts.
Authorities say a man and his two adult daughters were home at the time. All were outside by the time firefighters arrived, but the man was taken to the hospital with burns, while the daughters were treated for breathing problems.
Their names were not immediately released.
Some surrounding homes were evacuated as a precaution.
The cause remains under investigation.
