XI'AN - Falling rock killed one tourist and injured 18 others on Sunday morning in Northwest China's Shaanxi province, local authorities said.

Two of the victims are in critical condition.

The landslide occurred at Jinsixia Gorge, a local tourist site.

Falling stones crushed a rim skywalk and fell on the heads of several people, said Liu Fengxin, deputy manager of the Jinsixia management committee.

The deputy manager said the accident may have been caused by recent downpours.

The gorge has been closed temporarily.
