Bucks County officials say the two people killed after explosions at a Bristol nursing home were a resident and a staff member.

There’s still a lot of unanswered questions,” Pennsylvania Gov. Josh Shapiro said during a new conference Tuesday evening.

Officials have identified one of the two victims killed in a Bucks County, Pa., nursing home explosion that also left about 19 people hospitalized.

An apparent gas explosion collapsed part of a nursing home in Bucks County, Pennsylvania, leaving two women dead and 20 people injured.

An explosion and fire at a Pennsylvania nursing home killed two women -- one resident and one employee -- and wounded 20 other people, officials said. The "catastrophic" incident -- possibly caused by a gas leak -- unfolded Tuesday afternoon at the Silver Lake Nursing Home in Bristol, which is about 25 miles northeast of Philadelphia.

Three people, including two police officers, have been killed in an explosion in Moscow, Russian investigators said, just days after a car bomb killed a high-ranking general not far away.
