Ukrainian forces have successfully counterattacked against Russian troops, north of the country’s second largest city, Kharkiv.
They’ve retaken towns and villages, pushing Russian infantry and artillery back towards the border.
The fighting has been slow and costly but Ukrainian forces say they have gained the upper hand.
Kharkiv is just 35 miles from the Russian border. The Ukrainian military success could threaten the Russian aim of capturing large areas of territory in the east of the country.
Clive Myrie in Kyiv presents a BBC News at Ten special report from Quentin Sommerville and Darren Conway on the frontline north of Kharkiv.
