NATO allies and Ukraine are working together to make sure security guarantees for Ukraine are at such a robust level that Russia will never try to attack again, NATO chief Mark Rutte said on Friday, adding that Europe and the United States would be involved in providing them.

Russian Foreign Minister Sergei Lavrov said in an interview published on Sunday that a group of nations including United Nations Security Council members should be the guarantors of Ukraine's security.

The Trump administration has trumpeted a breakthrough in talks with Russia this month, claiming that Mr. Putin had accepted a proposal for the West to provide security guarantees for Ukraine as strong as Article 5 of the NATO charter, which stipulates that an attack on one alliance member is considered an attack on all.

KYIV - Russian missiles and drones slammed into Ukraine overnight Thursday with targets including a U.S.-owned business that President Volodymyr Zelensky said showed how Russia was not interested in peace.

Vice President JD Vance said Sunday that Russia has made "significant concessions" in talks to end its war with Ukraine but didn't rule out imposing more sanctions to pressure the Kremlin toward peace.

Speaking on NBC's "Meet the Press with Kristen Welker", Vance said Russian President Vladimir Putin has made several concessions, including that Ukraine will receive security guarantees protecting against future Russian aggression.
