Factory collapse in Pakistan leaves at least 20 people dead; Rescue operation under way

A major rescue operation is under way to save dozens of people thought to be trapped under rubble after a factory collapsed in Lahore, Pakistan. At least 20 people died when the plastic bag factory, which was under construction, collapsed on Wednesday. The cause of the collapse is still unknown. Building safety levels are often below standard in Pakistan. There are reports that the earthquake which hit Pakistan two weeks ago, or faulty construction work, may have contributed to the collapse. Two floors of the factory, in the Sundar Industrial Estate on the outskirts of the city, were operational, while a third was being built. Cranes and bulldozers are being used and the army is assisting in the rescue efforts. About 200 labourers are thought to have been in the building at the time of the incident. Other estimates in the Pakistani media have put the figure closer to 150 people.
