Ukraine has agreed to the U.S. peace proposal with only “minor details” remaining to be resolved, a U.S. official told CBS News on Tuesday. Rustem Umerov, a senior Ukrainian national security official, appeared to confirm the development, writing on X that Kyiv had reached an understanding on the “core terms” of the American plan during recent discussions in Geneva.

Ukrainian President Volodymyr Zelensky is expected to travel to the White House later this month to finalize the agreement.

Separately, the United States and Russia held undisclosed talks in Abu Dhabi on Monday, according to reports from Reuters and the Financial Times, as the Trump administration works to sustain momentum behind its evolving peace initiative. Those discussions are expected to continue on Tuesday, even as the conflict in Ukraine persists, Newsweek reported.

U.S. Army Secretary Dan Driscoll is meeting with a Russian delegation in Abu Dhabi as part of ongoing discussions over the proposed Ukraine peace plan. Kyrylo Budanov, the head of Ukraine’s military intelligence directorate (GUR), is also in Abu Dhabi at the same time, according to the Financial Times.

The original 28-point U.S. proposal, which Russia viewed favorably, was “refined” following U.S.–Ukraine talks in Geneva on Sunday to address concerns from Kyiv that the initial draft tilted too far toward Moscow and crossed several of Ukraine’s red lines. The most recent version of the plan under negotiation contains 19 points.

The diplomatic activity comes amid a surge of fighting on the ground. Ukrainian officials reported intense Russian strikes overnight into Tuesday, involving 460 drones and 22 missiles, resulting in multiple civilian deaths and dozens of injuries, including in Kyiv. Russia, in turn, said a large-scale Ukrainian drone attack on its territory had caused additional civilian casualties, the outlet added.

Romania, a NATO member, said it detected at least two Russian drones that breached its airspace during Moscow’s latest large-scale aerial attack on Ukraine, prompting the country to scramble fighter jets in response.

European allies, who were dissatisfied with President Trump’s initial peace proposal — a plan they were not involved in drafting — developed their own counter-proposal. They stated that no final framework affecting either the European Union or NATO could be agreed to without the consent of all member states. Russia rejected the European plan as unacceptable, Newsweek noted further.

The Kremlin said it is aware that the original U.S. draft has been revised but has not yet seen the updated version and had no new information to share regarding the ongoing talks in Abu Dhabi. Dmitry Peskov, spokesperson for President Vladimir Putin, described the first version of the U.S. peace plan as “a very good basis for negotiations.”

President Donald Trump has set a Thanksgiving deadline for a peace framework to be agreed. He wrote on Truth Social on Monday: “Is it really possible that big progress is being made in Peace Talks between Russia and Ukraine??? Don’t believe it until you see it, but something good just may be happening.”

Russian President Vladimir Putin lauded the Trump administration’s “energetic” efforts to end the conflict in Ukraine following a meeting in Alaska with Trump in August. He hinted that Moscow and Washington could reach an agreement on nuclear arms limitation as well.

Putin hosted a meeting of senior Russian officials at the Kremlin to advise them on the status of negotiations with the US on Ukraine.

“The current American administration… is making, in my opinion, quite energetic and sincere efforts to stop the hostilities, stop the crisis and reach agreements that are of interest to all parties involved in this conflict,” Putin said, as noted by CNN.

In his brief remarks, Putin said the summit with the US aims to “create long-term conditions for peace between our countries, as well as in Europe, and in the world as a whole.”

He suggested this broader peace can be achieved if, in the “next stages” of discussions with the US, “we reach agreements in the area of control over strategic offensive weapons.”
