I am informing you of our displeasure over the arrest of the Iranian civilian official without consulting the government of Kurdistan. That is a humiliation for the regional administration. You ignored our authority. I ask for his immediate release in order to maintain healthy relations between Iran and Kurdistan and for the prosperity of Kurdistan.
