For the second time in just over two months, a building has collapsed in Philadelphia, injuring several people.
Philadelphia's local FOX news station is reporting that six people are believed to be injured and the collapse has affected at least two row houses.
The collapse happened at 428 Daly Street. Police have evacuated the surrounding area.
Witnesses on the scene are saying they smell gas in the area, but the cause of the collapse hasn't yet been determined. A woman who lives in the neighborhood said she saw flames and smalled gas after an explosion.
A fire official on the scene said it seems there was an explosion and that rescue teams have completed a search of the area and aren't worried about other casualties. He said one person, a worker who was rehabbing the home that collapsed, is in critical condition at a hospital. The house was not occupied at the time.
The injured people include four adults, one infant, and a 15-year-old, according to NBC in Philadelphia.
Last month, another building collapse in Philadelphia killed six people and injured 13. The building inspector for that site committed suicide after it was revealed that he signed off on demolition work for the site despite complaints from the public.
