> So if I understand correctly, most the people arrested (teachers, journalists, police, etc) were Gulen activists or supporters ? Not just neutral or opposing the current governement ?

Well, it's unclear. Of course the Erdogan government claims they are, but we don't know - there could be a lot of innocent people in there too. And that's exactly the issue and source of contention.

Alright thanks a lot. Not easy to understand what happens in country I don't hear often about.
