BRUSSELS (AP) — NATO defense chiefs were due to hold a virtual meeting Wednesday, a senior alliance official said, as Western countries pushing for an end to Russia’s war on Ukraine devise possible future security guarantees for Kyiv that could help forge a peace agreement.

U.S. and European military planners have begun exploring post-conflict security guarantees for Ukraine, U.S. officials and sources told Reuters on Tuesday, following President Donald Trump's pledge to help protect the country under any deal to end Russia's war.

The protections that the US and Europe would be able to provide to Ukraine are similar to NATO's collective defense mandate.
