International media watchdog Reporters Without Borders accused the Chinese government of blocking access to the Google News service. The Paris-based group said the English version of the site had been inaccessible from China for the past 10 days. It said the block was intended to force users to turn to the Chinese version, which, the group said, filters out stories and news providers critical of China. Google has said it is aware of access problems from China and was investigating the cause. Google News gathers reports from some 4,500 news sources with headlines selected by a specially designed computer algorithm, with no human editorial intervention. Besides the main English service, Google publishes 15 other editions, including one specifically tailored for China.
