MALIPO, Yunnan Province, Sept. 3 (Xinhua) -- Thousands of rescuers are searching for 15 people who remain missing after a flood and a mudslide hit a town in southwest China's Yunnan Province on Sunday.

The disasters left five people dead, 15 missing and seven others injured in Mengdong Township, Malipo County, while forcing the evacuation of more than 1,500 residents, according to the local rescue headquarters.
