Turkish Foreign Minister Mevlut Cavusoglu made the promise amid reports Ankara-backed rebels were massing on the border in anticipation of an
impending operation against IS.
"We will provide all kinds of support to the Jarabulus operation," Cavusoglu said, promising to help "cleanse" IS from neighbouring countries.
"We do not want Daesh to exist in Iraq and Syria," he told reporters, using an Arabic acronym for the IS group.
