President Vladimir Putin has doubled down on his core demands for ending the war in Ukraine, stating that Russia will lay down arms only if Kyiv's troops withdraw from territory claimed by Moscow. Putin has long pushed for legal recognition of the Ukrainian territories Russia has seized by force.

A U.S. official has confirmed that Ukraine has agreed to a peace deal to end the war against Russia, with just "minor details to be sorted out."

Ukraine has come to a “common understanding” on the “core terms” of a U.S.-brokered peace deal in the war with Russia, its national security adviser Rustem Umerov said Tuesday. NewsNation’s Tom Dempsey has the latest development.

Ukrainian President Volodymyr Zelenskiy said on Thursday that Ukrainian and U.S. delegations are to meet this week to work out a formula discussed at talks in Geneva to bring peace and provide security guarantees for Kyiv.

United States Army Secretary Dan Driscoll held secret talks on Monday with a Russian delegation in Abu Dhabi in the United Arab Emirates to follow up on this weekend’s talks with Ukraine in Geneva that were intended to move the Ukraine peace process forward, a U.S. official told ABC News.

Top European and Ukrainian envoys have met in Geneva ahead of talks with U.S. Secretary of State Marco Rubio about President Donald Trump's proposal to end Russia’s war on Ukraine.

Ukraine and the United States have agreed to a deal to end the four-year war with Russia, with some details still to be worked out, a U.S. official confirmed to NewsNation early Tuesday.

Russia is threatening to reject President Donald Trump's Ukraine peace plan unless "key understandings" from his Alaska summit with President Putin are upheld.

The update was issued hours after Russia launched a wave of overnight attacks on Ukraine’s capital, Kyiv, with at least seven people killed in strikes that hit city buildings and energy infrastructure. A Ukrainian attack on southern Russia killed three people and damaged homes, authorities said.

The United States and Ukraine said they had created an "updated and refined peace framework" to end the war with Russia that apparently modified an earlier plan drafted by the Trump administration which Kyiv and its allies saw as too sympathetic to Moscow.
