Quentin Sommerville: BBC on patrol with the soldiers pushing Russia back

The BBC's Quentin Sommerville and cameraman Darren Conway have spent a week with the Ukrainian forces pushing Russia back towards the border of Kharkiv.

They've been reporting from in and around the village of Ruska Losova - just north of Kharkiv.

The fighting there has led to a dramatic fall in Russia’s shelling of the city but it has been slow and costly.
