A huge fire broke out in southern China on Friday at an unfinished Huawei research facility, sending massive plumes of smoke over the industrial city of Dongguan. The city government confirmed that firefighters were battling a fire at a Huawei building on Alishan Road, where the company is developing a research base. Footage broadcast online by state media channel CCTV showed dark clouds of smoke billowing out of a blue and white building near Songshan Lake. Huawei's spokesperson told AFP the company could not yet provide details on the fire. The Dongguan government said no casualties had been reported so far. The building on fire is a "steel structure, and has not yet been put to use," it said in a statement on the city administration's official social media account. Huawei's main office campus is in the southern city of Shenzhen, but it has a large sprawling office complex in nearby Dongguan. tjx/rox/gle
