Here is the appalling news: http://news.bbc.co.uk/2/hi/asia-pacific/8152385.stm. A Chinese consular officer insisted the festival director not to show a documentary about an exiled Uighur leader. Thanks to the festival director for taking the right decision.
The world should know what the Chinese are doing with Uighurs. I am very worried about them as I suspect they are being murdered by both the Han people and the government. I don't believe the official statistics of casualty. Chinese government has quelled people's movements in brutal ways in the past (e.g. the well-known Tiananmen square protest). I think this time it is no exception too.
