Turkey says it could seize IS stronghold with US

Turkey's foreign minister says joint US-Turkish military action could oust the

Islamic State group from

Syria .

Speaking in Antalya on Sunday, Foreign Minister Mevlut Cavusoglu says that operation could "easily advance to Raqqa," the main IS bastion in Syria.

American Special Operations forces and a coalition known as the Syria Democratic Forces have begun clearing areas north of Raqqa in preparation for an eventual assault on the city.

A major player in the coalition is the Kurdish People's Protection Units, or YPG, which Turkey unlike the United States views as a terrorist organisation.

Turkey is part of the US-led coalition against IS and a Turkish air base is being used to launch bombing runs against IS.

But the involvement of Kurdish factions in the anti-IS effort has strained US-Turkish relations.
