NATO defense chiefs are holding a virtual meeting to discuss security guarantees for Ukraine as part of efforts to end Russia's war on its neighbor

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.

Top U.S. and European defense officials spent much of this week privately discussing possible military options in Ukraine that would bolster the Eastern European country’s protections against Russia as part of a broader peace agreement.
