The Ukrainian military has halted a Russian advance in the east of the country and is now moving south, officials said on Friday. “We had very fierce battles in the Kupiansk and Lyman directions, but our soldiers stopped the enemy there,” Deputy Defence Minister Hanna Maliar told Ukrainian television. Ukraine’s summer counterattack has won multiple small victories, but Russian officials have denied Ukrainian claims that it has taken eight villages and pushed back Russian forces. That offensive is still in its early stages, with Ukrainian forces not yet advancing on the best-defended Russian positions in Donetsk and Luhansk.
