This article reports that Öcalan, the founder of PKK, has moved towards anarchism while in prison (after reading Murray Bookchin, apparently)... but I'm still getting a pretty strong Marxist-Leninst cult vibe from their website (http://www.pkkonline.com/en/).

Here's a quote from a 2012 interview with members of the Kurdistan Anarchist Forum:

"We are aware that Ocalan’s ideas have changed since he has been in prison. But we are not very optimistic about these changes. Also these changes have not, at least for the time being, been reflected in practice or organisationally in the PKK and PJAK. It is certainly true that the PKK has got many followers among the Kurdish people and have a big impact on Kurdish mass movements. They also talk about federalism. But none of this makes them in any way Anarchist organisations, nor does it make them compatible with Anarchism. They are, in fact, as far as one can get from Anarchists and Anarchism because Ocalan, first has not given up his authority and dominance over the mass movement, and second, they are still advocating nationalism and patriotism."

Still, anyone who would defy Turkish borders in order to resist ISIS sounds okay to me.
