Turkey has begun its military mission in northeastern Syria. The Turkish forces had started the operation together with pro-Turkish rebels, wrote Turkish President Recep Tayyip Erdogan on Wednesday on Twitter. Previously, he had phoned his Russian counterpart Vladimir Putin. Turkey has repeatedly stated in recent days that an offensive against the Kurdish militia YPG in northern Syria will begin "shortly".
Erdogan's government has repeatedly threatened to invade Syria for the third time in recent months after the operations in Jabulus and Afrin in order to fight the Kurdish militia YPG (read all the background).
Northeastern Syria has been controlled for years by the Kurdish Democratic Union Party (PYD) and the YPG militia as its military arm. Turkey regards the presence of the Kurdish militia at its border as a threat, as it is closely linked to the Kurdistan Workers' Party (PKK).
Ever since US President Donald Trump announced after a telephone conversation with Erdogan on Sunday to withdraw his troops from the region, an attack was more likely than ever.
Meanwhile, the Syrian Kurds called on Moscow to facilitate a dialogue with the government of the Syrian ruler Bashar al-Assad. She hopes that "Russia will assume the role of supporter and guarantor," declared the semi-autonomous administration of the Syrian Kurds. Moscow also assists Damascus militarily in the civil war.
