Turkey's incursion into Syria and the West's refusal to take back its IS fighters will prompt an attack, Mazloum Kobane said.
Another Islamic State (IS) terrorist attack in a Western city is "expected" because of the West's inaction and indifference in the region, the top Kurdish commander in Syria has warned.
General Mazloum Kobane, commander of the Syrian Democratic Forces (SDF), told Sky News the combination of the Turkish incursion into northern Syria, Western indifference to that and the West's unwillingness to take back its IS fighters is creating the perfect environment for an IS resurgence.
"The danger of the resurgence of ISIS is very big. And it's a serious danger.
"I think there are many people who don't know this but it's true. The Turkish aggression opened the space and provided hope for ISIS members," the general said.
On the prospect of another "spectacular" terror attack like the Manchester Arena bombing or the Paris Bataclan attack, the general was blunt.
"This is possible. It's one of the expected things that may happen in the future," he said.
Referencing the 5,000 IS fighters who are being held in Kurdish-run prisons, he said his forces do not have the capacity to guard them.
