Turkey has summoned US and Russian envoys to warn against supplying arms and support for Syrian Kurdish forces fighting Daesh group in Syria, a Turkish official said on Wednesday.

"The US and Russian ambassadors were called to the ministry yesterday (Tuesday) to convey Turkey's views about the PYD (Democratic Unity Party)," the foreign ministry official told AFP. "Necessary warnings were issued." Turkey labels the PYD as the Syrian offshoot of the outlawed Kurdistan Workers' Party (PKK) which has waged a bloody insurgency since 1984.
