ISTANBUL (Reuters) - Turkish President Tayyip Erdogan said on Tuesday the country s military operation in northwest Syria S Idlib province was largely completed but the neighbouring region of Afrin, controlled by a Kurdish militia, remained an issue. Turkey s army began setting up observation posts in Idlib this month under a deal with Russia and Iran to reduce fighting between insurgents and the Syrian government, but the deployment was also seen partly aimed at containing the YPG militia. Erdogan was speaking in parliament to members of his ruling AK Party.
