Those protesters very clearly demonstrated PKK flags, and expressed their support for their leader. The thing is, even though the EU recognizes PKK as a terrorist organization they do very few to stop their activities. Especially France and Germany, possibly because Kurds can vote in these countries and political parties want their votes. How can they get their votes? Just sit and watch them waving their flags, do nothing to stop PKK supporters financing PKK. European countries may not be directly supporting PKK, but they are definitely doing nothing against them.
