Ukraine President Volodymyr Zelensky warned of Russia's tactical move in its withdrawing troops from the Kyiv region in his daily address on Friday (April 1). As the war entered its sixth week, Mr Zelensky expressed his delight that some cities were being liberated, but acknowledged more difficult times lie ahead as he emphasised the importance of restraint.
"I am sure that it is extremely pleasant for each of you to read and watch the news that Ukrainian cities are gradually being liberated from the occupiers," he said.
"To the north of Kyiv, in the Chernihiv direction, in the Sumy region, the expulsion of the occupiers continues. They themselves are aware that they can no longer withstand the intensity of hostilities they could have maintained in the first half of March.
