Uyghurs
Contemporary scholars consider modern Uyghurs to be the descendants of a number of people, including the ancient Uyghurs of Mongolia who arrived at the Tarim Basin after the fall of the Uyghur Khaganate, Iranic Saka tribes, and other Indo-European peoples who inhabited the Tarim Basin before the arrival of the Turkic Uyghurs. DNA analyses indicate that the peoples of central Asia such as the Uyghurs are all mixed Caucasian and East Asian. Uyghur activists identify with the Tarim mummies, remains of an ancient people who inhabited the region, but research into the genetics of ancient Tarim mummies and their links with modern Uyghurs remains problematic, both to Chinese government officials concerned with ethnic separatism, and to Uyghur activists concerned that the research could affect their people's claim of being indigenous to the region.
Zeytinburnu
The Uyghur diaspora in the Küçükçekmece, Sefaköy, and Zeytinburnu districts of Istanbul, Turkey, are the source of Uyghur Turkistan Islamic Party Jihadists in Syria. The Turkey-based Uyghur website "Doğu Türkistan Bülteni", which supports the Turkistan Islamic Party, reported that the Uyghur diaspora in Küçükçekmece and Zeytinburnu were in fear after the assassination of Uzbek Imam Abdullah Bukhari and the Uyghurs were panicking over reports of Chinese loyalist Uyghur agents sent to Istanbul to hunt down separatist Uyghurs as Russia, Iran, and Assad were fighting against the Turkmens and Turkestan Islamic Party Uyghur fighters.
