U.S. trying Turkey's patience - Erdogan

EU fails to 'fully understand' Turkey’s challenges

EU fails to 'fully understand' Turkey’s challenges

Assad has defeated rebels in many parts of western Syria with critical help from Russian Federation and Iran.

Turkish Foreign Ministry on Wednesday summoned the U.S. Embassy Charge d'Affaires Philip Kosnett in Ankara over recent developments in Syria, Anadolu Agency reported citing a diplomatic source.

Earlier on Wednesday, Turkish Foreign Minister Mevlut Cavusoglu had warned Russian Federation and Iran to adhere to their joint accord signed with Turkey a year ago for announcing "de-escalation zone" in Syrian town Idlib. In 2016, the YPG-dominated Syrian Democratic Forces (SDF) pushed the Islamic State out of Manbij-a town on the western bank of the Euphrates-with support from the US-led coalition. Erdoğan has cast the YPG as "terrorists" closely connected to the Kurdish Worker's Party (PKK), which has been fighting an anti-government guerrilla campaign in southeastern Turkey for decades.

Lavrov noted that Moscow and Tehran have reached an important stage in preparation for implementing the initiative launched by Russia, Iran and Turkey to organize the Sochi Congress. This is also the reason for Vladimir Putin's telephone conversation with Recep Tayyip Erdogan. Military equipment is being deployed in Turkey's south-central province of Kilis, which borders Syrian territories controlled by the YPG and the PYD. The immediate trigger appears to be the series of mysterious drone attacks on Russian military bases in Syria's Latakia province since the start of the year. In other words, the perpetrators of the drone attacks were not local rebels under Turkey's supervision. Turkey, which guaranteed Idlib as a so-called "de-escalation zone, or a safe haven for the Syrian opposition, has protested the offensive on Abu al-Duhur and the mass bombardments. Careful operations should be carried out with intelligence from the ground or with technology".

The reports say that Syrian government forces, supported by Russian Federation were trying to regain control of areas controlled by Daesh and other rebel groups.

Turkey-US relations strained over the latter's support for the PKK/PYD terror group's presence and arming of the group in the region.
