More than 60 vehicles were stranded on a highway in southwest China's Tibet Autonomous Region Tuesday as a landslide had disrupted the road traffic.

The landslide happened at about 8 a.m. Tuesday at the section of Nyelam county along the road from the region's capital Lhasa to Kathmandu, capital of Nepal, said Zhang Min, an traffic police officer in the region.

No casualties were reported so far.

The road was damaged by the falling rocks, with the largest one of eight meters in diameter, said Zhang.

As the road was located between a mountain and a cliff, it was difficult to clear the rocks on the road, said Zhang.

"The stones just keep falling, which makes our work harder."

The traffic is expected to resume Wednesday morning, according to Zhang.
