At least two people are dead after a suspected natural gas explosion Tuesday at a Pennsylvania nursing home, where part of the building collapsed and some residents were trapped inside after the blast, officials said.

Two women were killed in a suspected natural gas explosion Tuesday at a Pennsylvania nursing home, where part of the building collapsed and trapped some prone, immobile residents inside, officials said.

"This is a very, very tragic moment," Pennsylvania Gov. Josh Shapiro told reporters Tuesday, describing the blast as "catastrophic."

The explosion happened about 2:20 p.m. ET at Silver Lake Nursing Home in Bristol Township, around 20 miles from Center City, officials said.

The dead were a resident and a Silver Lake staffer, officials said Wednesday. The Bucks County Coroner's Office identified the employee as Muthoni Nduthu, 52.

Twenty people were injured and taken to local hospitals, with one remaining in critical condition, officials said Wednesday.
