We travelled along the road to Manbij, a small town in northern Syria that has become the new frontline in the battle against the jihadist group Islamic State (IS).
Manbij sits on an intersection of roads linking the IS stronghold of Raqqa to the Turkish border and other areas under its control in Aleppo province.
The routes have become key to the group's ability to move fighters, weapons and supplies into and out of Syria.
On 31 May, a US-backed alliance of Syrian Kurdish and Arab fighters called the Syrian Defence Forces (SDF) began an operation to take Manbij and cut the supply routes.
After some heavy fighting, Manbij was encircled and completely cut off earlier this month.
