XINING, Aug. 21 (Xinhua) -- Twenty-one people were killed and three others remain missing after a rainstorm-triggered flood in northwest China's Qinghai Province, said local authorities on Wednesday.
Sudden rainstorms and hail battered Wulan County in Mongolian-Tibetan Autonomous Prefecture of Haixi around 7 p.m. Tuesday, washing away more than 20 workers, said the county government.
The workers were repairing a construction site at the time when the tragedy happened.
As of Wednesday morning, 21 people have been confirmed dead and seven others have been sent to a local hospital for injuries.
The search for three missing people is under way.
