Syria war: US warns over Turkish-Kurdish violence

The US says fighting between Turkey, pro-Turkish rebels and Kurdish-aligned forces in northern Syria is "unacceptable" and must stop.

Clashes in places where so-called Islamic State (IS) was not present were a "source of deep concern", the US envoy to the anti-IS coalition tweeted.

Turkish forces have attacked what they say are Kurdish "terrorists" since crossing the border last week.

But the Kurdish YPG militia says Turkey just wants to occupy Syrian territory.

Ankara says it aims to push both IS and Kurdish fighters away from its border.

Turkish forces and allied factions of the rebel Free Syrian Army (FSA) forced IS out of the Syrian border city of Jarablus on Tuesday and have since pounded neighbouring villages held by Kurdish-led, US-backed Syria Democratic Forces (SDF).
