Heads of Turkish, US defense discuss PYD issue in Belgium

He said Turkey will retaliate against any cross-border gunfire from the Kurdish YPG militia in Syria and will not remain silent in the face of activities by terrorist groups against Turkey overseas. Since then the Turkish-led forces have driven ISIS from a number of settlements in northern Syria.

In recent weeks, when the USA shot down a Syrian government war plane and an Iranian drone that were threatening US -allied Syrian fighters, the angry response from the Russians was to declare they would not use the deconfliction phone line. The U.S. also considers the PKK a terrorist organization, and has vowed it would never provide weapons to that group.

The PKK has been a waging three-decade armed campaign in Turkey.

The US and Turkey have been at loggerheads over Washington's support for the YPG.

Whether a small number of US troops is enough to deter Turkish forces from entering Tal Abyad and the surrounding region remains to be seen, but so far efforts to quell Turkey's fears through diplomatic means have proved futile. He was, of course, referring to the United States, whose troops are now all that seem to be standing between Turkish troops and the YPG.

Turkish President President Recep Tayyip Erdogan has warned in recent days that Turkish troops could cross into northern Syria to prevent the YPG from helping Kurds to form what he called "a state".

Turkey is also eager to move against ISIS, but has been so heavily involved in fighting the YPG as well that it's going to be hard for them to get into the area without completely derailing the US-backed Kurdish offensive and starting a whole separate war.

The SDF adviser also warned of the potential damage to the US-backed mission to clear the Islamic State group stronghold of Raqqa as SDF fighters would have to be diverted to Afrin to tackle Turkish and Turkish-backed rebel forces. Secretary of Defense Jim Mattis suggested on June 27 that the us may continue to arm the Kurds after the battle of Raqqa.

Among the issues discussed between the parties also was written guarantees of the US that detachments of the Kurdish People's Protection Units (YPG) and Kurdish Democratic Union Party (PYD) won't use USA armament against Turkey.

Mattis is scheduled to meet his Turkish counterpart, Defense Minister Fikri Işık, in Brussels on Wednesday, where both have arrived to attend a North Atlantic Treaty Organisation summit.
