You'll find the the "testimony" always comes from expats with ties to lunatic right-wing lobbying groups or who are based in Turkey.
The Turkey connection is really interesting. IIRC there have been Uighur volunteers involved with the jihadists sponsored by Turkey in the Syrian Civil War. Turkey is also closely aligned with Qatar, which has been struggling with Saudi Arabia for hegemomy over global fundamentalist Sunni Islam, especially through its control of al-Jazeera and influence over the Muslim Brotherhood.
