Fifteen people were injured Thursday when a gas line was struck in a New York village, destroying a residential building in an apparent explosion, authorities said.

The incident occurred around 12:15 p.m. in the Village of Wappingers Falls in Dutchess County.

Wappingers Falls Fire Chief Jason Enson said during a media briefing that an excavator ruptured the gas line. He said crews arrived to a working fire and people trapped in the rubble of the building after the explosion.

Ten people were injured in the initial incident, including eight adults and two children, Wappingers Falls police commissioner Paul Italiano said.

The victims had critical injuries when first responders arrived, he said, but the extent of the injuries was not clear.

Five first responders — one firefighter and four police officers — were also being treated at hospitals for minor injuries, including smoke inhalation, he said.

Two helicopters airlifted three of the injured people for medical treatment, and the other victims went by ambulance, Italiano said.

Eric Kiszkiel with Central Hudson Gas & Electric said at the news conference that crews had been doing routine maintenance in the area and were replacing a gas main.

The gas infrastructure in the area could date back to the 1930s or ‘40s, he said.
