From the NYT:
The American organization, the SITE Intelligence Group, posted the video, by the Turkistan Islamic Party, on its Web site on Wednesday, reporting that it had been issued in late August. In the video, according to SITE, the group’s leader, Abdul Shakoor Damla, claimed that attacks in July in Hotan and Kashgar, two southern Xinjiang cities, were acts of revenge for the Chinese government’s repression of the region’s ethnic Uighur population.
