Multiple people are reported to be injured following an explosion and fire at a nursing home in Bristol, Pennsylvania, officials say.
Emergency crews were called to the Silver Lake Nursing Home at about 14:00 local time (19:00GMT) on Tuesday. Firefighters believe some people may still be trapped inside the building.
An emergency management official told CBS, the BBC's US partner, that the fire remains active and part of the structure has collapsed. It's not clear how many people are injured, and the cause of explosion is still under investigation.
Images and videos posted on social platforms by local media outlets show a partially collapsed building with massive flames billowing out of it.
Local utility provider PECO said its crews had responded to reports of a gas odour at the facility in Bristol Township in the afternoon.
