China imposed a widespread ban on coverage of last week's high-speed train crash, forcing newspapers across the country to scrap pages of stories. The Hong Kong newspaper, the Sunday Morning Post said Chinese propaganda authorities had issued a censorship order late on Friday, banning all coverage of the crash except positive news or information released by the authorities. The ban came after state media published rare criticism of authorities over their response to the July 23 crash, which killed at least 40, injured almost 200 and called into question the fast expansion of China's high-speed rail network. The Post said the papers had planned special coverage to mark the seventh day after the disaster.
