Currently, 20 injured people are being treated in hospital, all of whom were out of critical condition, said a spokesman for the government of the Yunnan Province.

A truck carrying watermelons collided with the rear-end of a domestic tourist bus on an expressway in Chuxiong Yi Autonomous Prefecture at about 6:40 a.m. Saturday. Both vehicles veered off the road.

Fourteen people on the bus and two on the truck were killed instantly and two more bus passengers died en route to hospital. Three died in hospital.

The accident led to a traffic congestion on the expressway that links Kunming with Chuxiong. The traffic returned to normal by late afternoon.

Tourists on board the bus were mainly from Beijing, Shanxi and Hunan provinces, a traffic police officer told Xinhua
