More bodies of victims of the tragedy were recovered yesterday, raising the death toll to 53, the Geo News reported today.
Rescue officials said over a hundred survivors had so far been pulled from the wreckage of the factory.
No part of the building remained standing after the disaster, leaving dozens of workers trapped under the debris. It was unclear how many people were in the building when it collapsed or how many were still trapped, the report said.
According to reports, the factory's owner, who was adding a new floor to the building, had ignored advice from his contractor to stop construction after cracks in the walls following the October 26 earthquake.
The quake of magnitude 7.5 killed more than 300 people in Pakistan and the northern parts of neighbouring Afghanistan and damaged thousands of buildings.
