    The top leaders also requested relevant offices to properly handle the aftermath, discover the cause of the accident and resume rail operations at the earliest time possible.

    A high-speed passenger train jumped the track in the eastern province of Shandong early on Monday, striking another train and leaving 70 known dead and 416 injured as of late Monday, according to railway authorities.

    The casualties were from both trains, one of which was en route from Beijing to Qingdao, a summer resort in Shandong and venue of the Olympic sailing competition. The other was traveling from Yantai, Shandong to Xuzhou, Jiangsu Province.

    The high-speed train from Beijing, coded T195, derailed in the city of Zibo at about 4:48 a.m. and smashed into train 5034. The second train also left the tracks. At least 14 cars from both trains derailed.

    No foreign citizens were killed in the accident, which occurred just before the May Day national holiday passenger rush. However, four French nationals were hospitalized with bone fractures. They were identified as 54-year-old Pascal Boisson, his 14-year-old son Pierre Emmanuel Boisson, 22-year-old daughter Joanne Boisson, and his girlfriend Robin Naurence, 42.

     Vice Premier Zhang Dejiang rushed to Shandong on Monday morning to direct the rescue work. He also visited the injured at local hospitals and conveyed to the victims and their families the condolences of the Communist Party of China Central Committee and the State Council.

    Zhang also requested the Railways Ministry, Shandong Province and relevant agencies to make all-out efforts to rescue the injured, clear the scene and repair the facilities for an early resumption of operations.

    Preliminary investigations suggested the accident was caused by human error. Authorities have ruled out the possibility of terrorism.

    Further joint investigations are under way by the authorities of work safety, public security, supervision and railways.

    Immediately after the accident, two top officials of the Jinan Railway Bureau were sacked. The bureau's former director Chen Gong and former Communist Party chief Chai Tiemin face an investigation by the Ministry of Railways.
