Apple iPhone 5 maker Foxconn has been hit by an explosion at a plant in the Chinese city of Yantai in Shandong province.
It seems the fire began on the factory's finishing lines. According to Chinese tech blog MICGadget, the explosion was caused by "improper operation of workmanship on color spraying".
This is the second time a major disaster has engulfed a Foxconn plant. Last May, a factory in Chengdu that made PCs, laptops and printers caught ablaze. This latest plant employs 80,000 people, but there were no reports of any casualties.
Safety and conditions at Taiwanese IT giant Foxconn's facilities in China have been at the heart of a number of controversies over the last two years. In 2010, a spate of suicides at the company's factory in Shenzhen led to questions over working conditions, with Foxconn forced to increase workers' wages.
