Iran is concerned about Russia's and Turkey's rapprochement on the Syrian issue, a source in the Turkish Ministry of Foreign Affairs who wished to remain anonymous said.
According to him, after the crisis with Russian Su-24 was resolved, Moscow and Ankara began to cooperate on the situation in Syria, and Tehran was unhappy about it.
He stressed that Iran is also unhappy about Turkish military operation "Euphrates Shield", because it wants events in the region to unfold according to its plan.
