Expectations are low for the discussions in Istanbul, the first direct peace negotiations between Moscow and Kyiv since early 2022.

Some of Russia's demands include the withdrawal of Ukrainian troops from their own territory as a condition for a ceasefire, an unnamed Ukrainian source told Sky News.

Russian and Ukrainian negotiators will meet in Istanbul on Friday for their first peace talks in more than three years as both sides come under pressure from U.S. President Donald Trump to end Europe's deadliest conflict since World War Two.
