Russian media: Putin signs 'documents' on formally annexing 15% of Ukraine's territory.

National security advisers from the Coalition of the Willing countries, led by the U.K. and France, have agreed to meet in Ukraine on Jan. 3, according to Zelensky. The meeting will be followed by another meeting among state leaders, planned for Jan. 6 in France.

"Each restoration requires significant time and resources, as the level of damage varies across regions," Deputy Energy Minister Olha Yukhymchuk said.

Ukraine struck a Russian drone storage facility at Donetsk Airport in occupied Donetsk Oblast, Unmanned Systems Forces commander Robert “Madyar” Brovdi said on Dec. 30.

Ukraine's top commander said a battalion commander will face a legal review after Ukrainian troops abandoned a command post in the Huliaipole sector, leaving behind equipment and potentially sensitive materials.

Zelensky tells Fox News' Bret Baier that Ukraine has demonstrated concrete steps toward peace over the past month and raised the possibility of a referendum on the peace plan. At the same time, a referendum would not legitimize withdrawing from Ukrainian territory, given the current security realities.

U.S. President Donald Trump said Dec. 29 that Russian President Vladimir Putin told him Ukraine had tried to attack Putin's residence, an allegation Kyiv has denied. "I learned about it from President Putin today. I was very angry about it," Trump said.

Zelensky dismissed Russian claims that Ukrainian drones targeted Putin’s residence as “another lie,” warning Moscow is using the allegation as a pretext for possible strikes on Kyiv and government buildings.

Kyiv failed to implement nine indicators in the last three months of 2025, the highest number missed in any quarter since the Ukraine Facility began in 2024, according to a Dec. 29 assessment by RRR4U.

"President Trump has concluded a positive call with President Putin concerning Ukraine," said White House Press Secretary Karoline Leavitt.

Ukraine’s Southern Operational Command says Huliaipole is now a gray zone, with no clear front line anymore, according to spokesperson Vladyslav Voloshyn.
