Photoblog: On the road into Mosul

Standing between the combined forces of Iraqi troops and Kurdish Peshmerga fighters in the Nineveh desert and the thousands of Islamic State group militants holed up in the city of Mosul is the town of Qaraqosh.

The small town is surrounded. Iraqi special forces - "The Golden Division" - has just arrived. It will be the next domino to fall on the march to Mosul.

Travelling here, we have seen hundreds of troops making their way to the front lines. After months of military planning and political posturing, these troops know the battle has begun.
