Ukraine has agreed to a peace deal with only "minor details" yet to resolved, CNN reported on Tuesday, citing a U.S. official.

"The Ukrainians have agreed to the peace deal. There are some minor details to be sorted out, but they have agreed to a peace deal," the official was quoted as saying.

However, Ukrainian President Volodymyr Zelensky said more work was needed.

"Following the meetings in Geneva, we see many prospects that can make the path to peace real. There are solid results, and much work still lies ahead," he said on social media on Tuesday.

On Monday and Tuesday, U.S. Army Secretary Dan Driscoll held talks with Russian officials in Abu Dhabi on the deal, according to a statement from the U.S. Army.

"Late Monday and throughout Tuesday, Secretary Driscoll and team have been in discussions with the Russian delegation to achieve a lasting peace in Ukraine," U.S. Army spokesman Lt. Col. Jeff Tolbert said in the statement.

Rustem Umerov, Ukraine's secretary of national security and defense council, said that Zelensky is planning to visit Washington to "complete final steps and make a deal with President (Donald) Trump."

Umerov wrote on social media platform X that Ukraine had "reached a common understanding on the core terms of the agreement discussed in Geneva."

"We now count on the support of our European partners in our further steps," he said.

The 28-point draft aimed at ending the Russia-Ukraine conflict has been trimmed to a 19-point framework drafted by the United States and Ukraine over the weekend in Geneva, multiple media outlets reported Monday.

Representatives from the United States, Ukraine and European countries met in Geneva on Sunday as the White House pushed for agreement on the 28-point plan by Thursday set by Trump as a deadline.

"Many of the controversial provisions were either softened or at least reshaped" to get closer to a Ukrainian position or reduce demands on Ukraine, Oleksandr Bevz, a Ukrainian official who participated in the Geneva talks, was quoted by The Washington Post as saying.

The new draft leaves the most contentious issues for Trump and Zelensky to decide, according to multiple media reports.

The earlier 28-point version would have required Ukraine to cede territory in eastern Ukraine, reduce its military and forswear NATO membership. The plan thus crossed several long-standing Ukrainian red lines, drawing criticism from Ukraine and across Europe.
