At the time of the fire, more than 20 people were in the building. The fire was triggered by an extremely flammable chemical and then spread, it said.
Due to dangerous working conditions, fires in factories and mines are not uncommon in Pakistan. In 2015, at least 30 people died in the collapse of a factory building in Lahore in the east of the country. In 2012, more than 250 people were killed in a fire at the Ali Enterprises textile factory in Karachi.
