Chinese authorities in the restive far western region of Xinjiang have demolished a mosque for refusing to put up signs in support of this August's Beijing Olympics, an exiled group said on Monday. The mosque was in Kalpin county near Aksu city in Xinjiang's rugged southwest, the World Uyghur Congress said. The spokesman's office of the Xinjiang government said it had no immediate comment, while telephone calls to the county government went unanswered. “China is forcing mosques in East Turkistan to publicise the Beijing Olympics to get the Uighur people to support the Games (but) this has been resisted by the Uighurs,” World Uyghur Congress spokesman Dilxat Raxit said in an emailed statement. Beijing says Al-Qaeda is working with militants in Xinjiang to use terror to establish an independent state called East Turkistan. Oil-rich Xinjiang is home to 8 million Turkic-speaking Uighurs, many of whom resent the growing economic and cultural influence of the Han Chinese. Dilxat Raxit added that the mosque, which had been rebuilt in 1998, was accused of illegally renovating the structure, carrying out illegal religious activities and illegally storing copies of the Qur'an. “The Qur'an copies in the mosque have been seized by the government and dozens of people detained,” he said. “The detained Uighurs have been tortured”. The Olympic torch relay passed through Xinjiang last week under tight security and tight controls over foreign media covering the event.
