According to Reuters, citing sources in the Turkish Foreign Ministry, Ankara has summoned the US charge d'affairs, Philip Kosnett, over the situation in Syria.
The Turkish authorities and Washington haven't yet officially confirmed the information; however, Ankara has repeatedly slammed the US support and arms supplies for the Kurdish militia fighting against terrorists mostly as part of the Syrian Democratic Forces (SDF) rebels.
In December 2017, the US announced its decision to halt arms supplies to the Kurdish People's Protection Units, as was earlier promised to the Turkish leadership. However, Turkish Deputy Foreign Minister Ahmet Yildiz told Sputnik that Washington was yet to prove it is cutting its arms supplies to Syrian Kurds with documented evidence, as statements from the White House continued to differ on the issue.
Ankara considers the YPG to be affiliated with the Kurdistan Workers' Party (PKK), a designated terrorist organization in Turkey, that has fought a protracted armed struggle against Turkey to achieve independence or autonomy.
