Ukrainian President Volodymyr Zelenskiy on Saturday said it was absurd Russia had assumed the rotating presidency of the United Nations Security Council, adding this showed the institution's "total bankruptcy". On Saturday Russia took over the presidency of the UN's top security body, which rotates every month. The last time Moscow held the post was in February 2022, when its troops launched a full-scale invasion of Ukraine. "Unfortunately, we ... have some obviously absurd and destructive news," Zelenskiy said in an evening video address, adding that Russian shelling had killed a five-month-old boy on Friday. "And at the same time Russia is chairing the UN Security Council. It's hard to imagine anything that proves more the total bankruptcy of such institutions," he said. The Kremlin said on Friday it planned to "exercise all its rights" in the role. The United States on Thursday urged Russia to "conduct itself professionally" when it assumes the role, saying there was no means to block Moscow from the post. Zelenskiy said it was time for a general overhaul of global institutions, including the Security Council.
