Firefighters took almost five hours to control blaze at construction site in Shandong

An indoor stadium under construction in China has been badly damaged by fire according to state press.

The lotus-shaped facility in Ji’nan, Shandong was being built for the China National Games, which happen once every four years.

More than 300 firefighters took almost five hours to put out the flames, which spread to a quarter of the roof. No casualties were reported.

The fire is thought to have started when electric welding equipment set light to insulation material.
