Russian negotiators at peace talks in Istanbul demanded Ukraine pull its troops out of all the Ukrainian regions claimed by Moscow before they would agree to a ceasefire, a senior Ukrainian official familiar with the talks told Reuters.

Russia and Ukraine’s first direct talks in three years began Friday with hopes as dim as the gray Istanbul skies.

But the two sides failed to broker a temporary cease-fire or a meeting between their two leaders, a sign of how far apart they remain on ending the conflict.
