Russia’s foreign minister has cast fresh doubt on peace talks, questioning “the legitimacy” of Ukrainian president Volodymyr Zelensky to sign any future agreements after targetting a US factory in a large bombardment on Ukraine.

Special U.S. envoy Steve Witkoff says Russian leader Vladimir Putin agreed to allow the U.S. and Europe to offer Ukraine a security guarantee resembling NATO's collective defense mandate.

European NATO leaders must not be naive when discussing a Ukraine peace force but face up to the reality that they would need to deploy tens of thousands of troops to the country for the long term, the head of Germany's soldiers' union said.

Western defense companies are increasingly establishing new presences in Ukraine and working directly with Ukrainian companies.

President Donald Trump on Sunday night declared that Kyiv would not be regaining Moscow-annexed Crimea, nor would it be allowed to join NATO.

As Trump pushes for peace, Ukraine accuses Russia of a deadly drone and missile strike, "as if there were no efforts by the world to stop this war."

White House Press Secretary Karoline Leavitt told the press President Trump has ruled out boots on the ground in Ukraine for peacekeeping.

U.S. military leaders are expected to meet with their NATO counterparts Wednesday to discuss potential security guarantees for Ukraine. Ukrainian President Volodymyr Zelenskyy has stressed that strong security guarantees are key to lasting peace,
