John Hinderaker, blogging at Power Line, reports on the arrest of three men, two of whom wanted to leave the U.S. to join ISIS in Syria. Two were Uzbeks and one a Kazak. Hinderaker labels them "non-Muslims" but provides no evidence of their faith.
An Associated Press story on the arrests says nothing about them being non-Muslim and infers strongly that at least one was very involved in Islam. Checking the CIA's World Factbook online, I find that Uzbekistan is 88% Muslim and Kazakstan is 70% Muslim.
I expect what Hinderaker meant was that these men were not Arabs. Most people from both countries are considered Turkic - not precisely Turkish but members of the same ethno-languistic group.
