Uyghurs in Turkey expressed disappointment on Thursday after a U.N. report found China's detention of Uyghurs and other Muslims in its Xinjiang region may constitute crimes against humanity.

Uyghurs interviewed by in Istanbul said the U.N. report, issued on Wednesday, came late and should have gone further in challenging China over its treatment of their community in Xinjiang.

Some 50,000 Uyghurs are estimated to live in Turkey, the largest Uyghur diaspora outside Central Asia. Turks have close ethnic, religious and linguistic ties to the Uyghurs.
