Pennsylvania officials said Tuesday evening that three people were killed, and 20 others were wounded in gas explosions at a nursing home in Bristol.

Pennsylvania Democratic Gov. Josh Shapiro said earlier Tuesday that two people died in the explosion, but Bristol Township police later told CBS News that another person was found dead at Silver Lake Nursing Home in Bucks County.

Police also told the outlet that 20 people were injured in the blast and subsequent fire, and the victims were sent to five area hospitals, and all the missing nursing home patients have been found.

"Tonight in Bristol, our first responders displayed extraordinary courage as they bravely ran towards danger to get residents, their loved ones, and staff at Silver Lake Nursing Home to safety," Shapiro said on X. "Lori and I are praying for those who are injured, those who are missing, and the families of those who are now about to celebrate Christmas with an empty chair at their table."

Bristol Township Fire Chief Kevin Dippolito said they believe a gas leak caused the two explosions and a fire to break out at the nursing home, though the cause of the gas leak was not immediately clear.

The incident comes after the state found the nursing home was not in compliance with several requirements of the Life Safety Code as of October, including lacking a Life Safety Code Floor Plan that shows where fire barriers, exits and smoke barriers are.
