What proxies are you talking about? Your belief is based upon suppositions and definitely not facts. I am from Turkey also and I know. Iran fights PJAK and if they find any Turkish citizens among the captured terrorists, they deliver them to the Turkish Jandarma in the border. Just look up the news for the last decades in the archive of any online website. Maybe you missed or maybe you are just an excited youth.
Unlike Erdogan who feeds the terrorist leader in the country in Imrali and sleeps with another terrorist in the Northern Iraq. Iran fights the PKK/PJAK not with words but in the battlefield.
And like any traitor leader would do, Erdogan and its media also show the "enemy" as an outsider person/group/country. But, they are the enemies of the nation themselves.
As for the OP, I see it is already pointed a few times that Iran is fighting "
Jundallah",
Jaish "al-Adl",
PJAK,
MKO, as well as drug-trafficking and others.
And the terrorist groups in the list however are mainly salafi-wahabis (that sadly even drew some sunnis to their devillish coalition), and they are not available in Iran. (Iranian vigilant nation is mainly of shias and some sunnis). It is rather Saudi Kingdom, Qatari Sheikhdom, etc. create and support the terrorist groups such as ISIL, al-Qaeda, Nusra, Boko Haram, etc. But what they forget is, those dogs will one day bite the hands which feed them.
