70 people have been killed and 420 injured after a passenger train left the rails and hit another train in eastern China.
The train from Beijing was travelling to Qingdao, the coastal city that will host the Olympic sailing competition in August, when it derailed, causing the other train to leave the tracks also.
The accident, the worst in China in more than a decade, happened in the city of Zibo in Shandong province.
The crash was caused by human error according to preliminary investigations. Terrorism has been ruled out as a possible cause.
Witnesses said many passengers were able to climb out of the wrecked train carriages shortly afterwards.
The other train was on its way to Xuzhou in the eastern Jiangsu province, from Shandong's Yantai.
Railway Minister Liu Zhijun arrived at the scene to oversee rescue efforts. He has demanded an investigation.
The accident has disrupted traffic on a major rail route linking Jinan, the capital of Shandong, to Qingdao.
In January, a high-speed train ploughed into a group of railway workers in Shandong province, killing 18 people.
The Chinese government said earlier this year that 101,480 people died in 2007 in more than 500,000 transport, industrial and other accidents.
