NANNING -- Three people died and one remains missing after intense rain triggered flash floods in South China's Guangxi Zhuang autonomous region, local authorities said on Saturday.

On Friday and Saturday, torrential downpours hit the county of Longlin, resulting in a flash flood in Yancha township. This surge of water left four people missing, after a temporary shelter they were staying in on a hillside was swept away.

Upon receiving a report of this incident on Saturday, local emergency response, public security, fire and health authorities promptly launched search and rescue operations. Three of the missing individuals were later found in a mountain stream gully, with all three declared dead.

Efforts to locate the remaining missing person are still underway.
