UN Secretary General Antonio Guterres rejected Ukraine's invitation to the first Global Peace Summit, but accepted an invitation to Kazan from Putin, this does not contribute to peace, the Ukrainian Foreign Ministry said.

"The UN Secretary General declined Ukraine's invitation to the first Global Peace Summit in Switzerland. He did, however, accept the invitation to Kazan from war criminal Putin. This is a wrong choice that does not advance the cause of peace. It only damages the UN's reputation," the department said on X.

Earlier, the British newspaper, The Telegraph, reported that Putin would hold a meeting this week in Kazan with the leaders of more than two dozen countries, including Chinese leader Xi Jinping, Indian Prime Minister Narendra Modi and UN Secretary General Antonio Guterres.
