BEIJING (AP) — At least 12 people have died in two landslides in southwestern China and rescuers are looking for 34 missing, Chinese state media reported Wednesday.

A landslide on Tuesday night buried 21 houses and caused at least 11 deaths in Guizhou province's Shuicheng county, said state broadcaster CCTV.

Eleven people were rescued while another 34 remain missing. Heavy rainfall is believed to be the main cause, CCTV said.

More than 800 rescuers have been scouring the area, where continuous rainfall and the mountain's steep slopes have hampered search efforts.

One person died and six others are unaccounted for after an earlier landslide hit a village in Hezhang county in Guizhou on Tuesday afternoon. The landslide happened at a highway construction site, the Xinhua state news agency reported.
