Ukraine and Russia hold ‘productive’ first day of US-led peace talks in Abu Dhabi

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

Ukrainian and Russian negotiators have held a productive" first 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 that are due to continue on Thursday come after Volodymyr Zelenskyy accused Moscow 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.
