Five people have been rescued while an unknown number were still missing Monday after a rain-triggered landslide engulfed two vehicles in east China's Fujian Province, local officials said.

The landslide hit a bus and a van at around 12 a.m. in Yanping District, Nanping City, said Zhang Guowang, head of the district's Committee of the Communist Party of China.

Five people on the bus had been rescued as of 5 p.m. but it was unknown how many were still missing. Zhang said the bus was carrying 12 passengers when it departed but that it is unknown how many people had already gotten off the bus before the landslide hit.

"We know for sure the van had only a driver, who is still missing," Zhang said.

Rescuers were still searching for the missing, said Huang Xiong, head of the district government.

Heavy rainstorms have pounded Fujian since Sunday and more rain is forecast for Monday and Tuesday.
