费城拆除一座建筑发生事故6人死亡

Rescue workers in Philadelphia Pennsylvania continue to look for survivors Thursday, a day after a four-story building under demolition collapsed into a neighboring thrift store, killing six people. 

Late Wednesday, a woman was found in the rubble more than 10 hours after the accident, raising the number of survivors to at least 14.

City officials say there were no existing violations on the building.  They say the demolition company had proper permits for the work it was doing in downtown Philadelphia.

Authorities say they do not know how many people were in the thrift store or on the sidewalk when the accident happened Wednesday.
