The first three-way peace talks between Russia, Ukraine, and the US have ended in Abu Dhabi with no apparent breakthrough, as fighting rages. Ukrainian President Volodymyr Zelensky raised the possibility of a second meeting as early as next week, while an American official said a new round would begin on 1 February.

The two-day talks ended after waves of Russian air strikes targeted Ukraine's badly damaged energy infrastructure, killing one person and injuring 35 others, Ukrainian officials said. Russia accused Ukraine of attacking an ambulance in Ukrainian territory under its control, killing three medics. Later, it reported a Ukrainian missile attack on energy infrastructure in Belgorod.

The BBC could not independently verify the reports. The talks in Abu Dhabi were the first trilateral meeting since the Kremlin launched its full-scale invasion of its neighbour in 2022. The central focus of the discussions was the possible parameters for ending the war, Zelensky posted on X.

I highly value the understanding of the need for American monitoring and oversight of the process of ending the war and ensuring genuine security. All sides had agreed to report back to their capitals and co-ordinate further steps with their leaders, he added.

We’ve agreed that the next round begins next Sunday in Abu Dhabi again, an unnamed US official told reporters. The decision to hold further talks was a good sign, and a lot of work had been done over the two days of negotiations, the official added.

Vitali Klitschko, mayor of Kyiv, reported that one person had died and four were wounded by Russian air strikes, while 31 were injured in Kharkiv. With temperatures dropping to around -12C, the attacks have left thousands of buildings without heating, raising humanitarian concerns.

The ongoing dialogue reflects a critical step towards potential peace, but significant challenges remain as both sides continue to strike at each other amidst talks.
