In peace talks this week, Russia said it would reduce attacks on the capital, Kyiv, and the city of Chernihiv, but Ukrainian and Western officials rejected the pledge, saying Moscow troops were simply being reorganized. “This is part of their tactics,” Zelensky said in a midnight speech. “We know they are moving away from the areas where we are hitting them to focus on others who are very important … where it can be difficult for us,” he said. In particular, he warned, the situation in the south of the country was “very difficult”. “In Donbas and Mariupol, in the direction of Kharkov, the Russian army is accumulating the potential for attacks, strong attacks,” he said.
