Twenty-thousand Syrian refugees have been returning to the border town of Jarablus, after so-called Islamic State (IS) militants were forced to retreat by Free Syrian Army soldiers, backed by Turkish troops.

Turkey is hoping to establish a 70-mile zone, with no IS presence, along the Syrian side of the border, while also excluding any Kurdish fighters.

Correspondent Mark Lowen and cameraman Goktay Koraltan are among the first western journalists to reach the town of Jarablus.
