One person is missing and four sustained injuries after a landslide on Wednesday evening in Chongqing Municipality, southwest China.

The landslide occurred at 6:40 p.m. on the northern bank of the Daning River, a tributary of the Yangtze River, in Wushan County. Strong waves caused 13 vessels, mostly fishing boats, to sink.

An initial check showed all people onboard the anchored ships had gone ashore before the landslide. However, one person, who was on the bank, is unaccounted for and four others were injured, one of whom is in a critical condition, an official with the Yangtze River Navigational Affairs Administration said.

Six maritime patrol vessels and a number of salvage ships have been despatched to aid rescue efforts, according to the administration, which is based in Wuhan, capital of Hubei Province.

The search for the missing is under way.
