Ukraine’s president, Volodymyr Zelenskiy, has announced the return of five military commanders who were previously expected to have to remain in Turkey until the end of the war. The men led the defence of the city of Mariupol until surrendering to Russian forces last year, and had been sent to Turkey under the terms of a prisoner exchange brokered by Ankara. Russia has said the return of the men represents “nothing more than a direct violation of the terms of the existing agreements” by both Ukraine and Turkey. The Turkish president, Recep Tayyip Erdoğan, said on Saturday Russia’s leader, Vladimir Putin, would visit Turkey in August.
