>> The new front in Syria's war that's pushing Turkey and US relations to the brink. The Turkish military are pressing ahead with clearing a northern enclave of Syria that's held by the Kurdish YPG. That's also America's main Syrian ally on the ground. Tayyip Erdoğan is warning they would extend this operation from Afrin to the town of Manbij.
That move could potentially see Turkish forces coming face to face with US troops who are based there. President Trump will raise concerns in a phone call with his Turkish counterpart on Wednesday. On Day 5 of the fight, the Turks have dubbed Operation Olive Branch. Turkey says, two of its soldiers have died, while dozens of fighters have been killed on all sides from the Turkey-backed Free Syrian Army to the YPG.
Those figures coming from a Syrian monitoring group who also say Turkish airstrikes and shelling has killed 28 civilians. In European cities, Kurds and their supporters have taken to the streets. In Syria's Raqqa, hundreds marched calling Erdoğan a traitor. Turkey sees the YPG as an offshoot of the PKK who have waged a decades-long insurgency in southeast Turkey.
It has said it won't allow Kurdish fighters to control a strip of land on its southern border. But the move could threaten US plans to stabilize and rebuild a large area of northeast Syria beyond the control of the Syrian regime. Washington armed YPG fighters to drive out Islamic State, now they're being attacked by a NATO ally.
