At least 32 people are missing after floods destroyed the makeshift buildings of a hospital in Wenchuan County in southwest China's Sichuan Province early Saturday.

No casualties had been reported, a spokesperson with the county government said.

Heavy rain triggered landslides in several towns of Wenchuan County, where an 8-magnitude earthquake claimed almost 70,000 lives on May 12, 2008.

Floods destroyed prefabricated buildings of the hospital in Yingxiu Town, which was the epicenter of the 2008 quake, leaving at least 32 people missing.

In Yinxing Township, a barrier lake was formed by the landslide in a section of the Minjiang River, said the spokesperson.

A 200-meter section of National Highway 213, the only highway linking Wenchuan to the provincial capital of Chengdu, was inundated with water four meters deep.

More than 500 residents of Yinxing had been evacuated.
