Beijing: At least nine people were killed and 36 others injured, including eight seriously, after a bus veered off an expressway section in southwest China.

The 44-seat sleeper coach had 46 people on board including two drivers, when the accident happened in Nanhua County, Chuxiong Prefecture in Yunnan Province on Wednesday night, state-run news agency reported.

Local authorities said the passengers included two children less than three years of age.

The coach owned by Baoshan Transportation Corporation was en route from the provincial capital of Kunming to Tengchong, a scenic spot in Baoshan City bordering Myanmar, when it bumped into the expressway guardrail on a viaduct linking two expressways and plunged over 10 metres to the ground.

All the injured have been taken to hospital.
