ANKARA Turkey's allies are still providing weapons to the Syrian Kurdish YPG militia, Deputy Prime Minister Veysi Kaynak said on Wednesday, asking "what business does a terror group have at the peace table?".
The YPG is one of the United States' strongest allies in its fight against Islamic State in Syria. Ankara regards the Kurdish militia as a terror group closely linked to militants who have fought a three-decade-old insurgency in southeast Turkey.
Syrian peace talks are planned to be held in the Kazakh capital Astana, but the date and participants remain unclear.
