WEST CHESTER, PA (CBSMiami/CNN) -- At least 20 people are injured after a nursing home near Philadelphia burst into flames overnight.
The fire ripped through the home late Thursday, not only injuring residents, but also forcing more than 140 people to evacuate into the cold night.
The fire at the Barclay Friends assisted living facility in West Chester started shortly before 11 p.m., West Chester Fire Chief Mike McDonald said. Video from CNN affiliate KYW showed huge flames consuming a number of units in the complex.
Outside the home, first responders and neighbors tended to evacuees who were wrapped in blankets, sitting on plastic chairs and wheelchairs in the cold, with temperatures in the mid to low 40s.
At least 20 people were taken to hospitals with injuries, including an emergency medical service responder, Chester County spokeswoman Patty Mains said. Details about the injuries were not immediately available.
About 140 to 150 people -- residents and staff members -- were evacuated, Mains said.
"Emergency personnel have relocated residents to several locations and are working to connect the residents who were transported to the local hospitals or shelter for safety to their families," said McDonald, the fire chief.
The fire was under control shortly before 1:30 a.m. ET, though firefighters still were battling hot spots, McDonald said.
The fire's cause was under investigation, he said.
Susan McCardell, whose mother lives at Barclay Friends, told KYW that facility staff and others appeared to do a good job of getting residents out of the complex.
"It seemed like they were being taken care of and moved to a safe and warm facility. We're very grateful to see that so many people were taken care of, and we're happy to find our mom," McCardell said.
