Major obstacles to viable deal remain after Volodymyr Zelenskyy accuses Moscow of violating energy truce

Europe live – latest updates

Ukrainian and Russian negotiators have begun a second round of US-led peace talks in Abu Dhabi as Washington seeks a pathway to end the nearly four-year war in Ukraine.

The two-day trilateral talks starting on Wednesday come after Volodymyr Zelenskyy accused Russia of exploiting a US-backed energy truce last week to stockpile weapons before launching a record number of ballistic missile attacks at Ukraine on Tuesday.

Despite renewed diplomatic efforts by the Trump administration, the prospects for a viable peace deal remain unclear, with Moscow continuing to press its maximalist territorial demands. The Kremlin has repeatedly said any settlement must include Ukraine ceding the entire eastern Donbas region, including areas still under Ukrainian control. Kyiv has rejected such terms, saying the conflict should instead be frozen along the current frontline and ruling out any unilateral withdrawal of its forces.
