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.

Officials told Reuters that the Pentagon is carrying out planning exercises on the support Washington could offer beyond providing weapons.

The incident highlights the continuing volatility near NATO's eastern border as Russia intensifies aerial attacks on Ukraine.
