Russian Deputy Foreign Minister Alexander Grushko reportedly said that the Kremlin wants an "ironclad" guarantee that Ukraine will be prohibited from joining the North Atlantic Treaty Organization (NATO), as the Trump administration works to broker a deal to end the fighting. "We will demand that ironclad security guarantees become part of this agreement," Grushko was quoted by the Russian newspaper Izvestia as saying, according to Reuters. "Part of these guarantees should be the neutral status of Ukraine, the refusal of NATO countries to accept it into the alliance."
