Six people died and two others were injured after a water storage fell down and hit a factory late Tuesday in central China's Henan Province, local government sources said Wednesday morning.

Rescue work has completed, the sources added.

One building of the Dongxishan Ore Dressing Factory in Wangwu Town of Jiyuan City collapsed after being hit by the factory's water storage at 6 p.m. when eight workers were inside the building.

Five died and two others were injured at the scene, and another was believed to be trapped. Rescuers retrieved the body of the trapped worker under the debris at around 6:00 a.m. Wednesday.
