At least 18 people were killed and 51 injured when the roof of a factory collapsed near the eastern Pakistani city of Lahore on Wednesday, officials said. The incident comes less than two weeks after a powerful 7.5-magnitude earthquake ripped across Afghanistan and Pakistan, killing nearly 390 people, levelling thousands of homes and causing structural damage to major buildings....The collapse occurred at a Rajput Polyester plastic bag factory in the Sundar industrial estate around 30 miles (45km) south-west of the city centre. Punjab chief minister Shahbaz Sharif said it was possible the building had been damaged after the 26 October earthquake. “I have heard about the earthquake affecting the building but according to labourers the owner continued to build an extension.”...Pakistan has a poor safety record in the construction and maintenance of buildings. In 2014 a mosque collapsed in the same city, killing at least 24 people.
