Turkey says it is threatened by a new US-trained army of 30,000 mainly Kurdish soldiers on its border.

US support for Kurds in Syria is leading to threats of retaliation from Turkey.

A coalition of countries led by the US is planning a 30,000-strong force in Syria, just across the border with Turkey.

Turkey's President Recep Tayyip Erdogan thinks the Kurdish-led force is a threat and is vowing to attack the city of Afrin in northern Syria.

Afrin is a major stronghold of YPG Kurdish fighters. Turkey considers the YPG a "terrorist" group linked to the Kurdistan Workers' Party (PKK). Its PKK fighters have waged a long war against Turkish dominance.

How much volatility will be added to the war zone?
