Germany, France, the U.K. and Poland outmaneuvered the Kremlin by persuading Ukraine’s Zelensky to accept Trump’s cease-fire demand. Russia’s leader balked.

Ukrainian President Volodymyr Zelensky accused Russian President Vladimir Putin of being too "afraid" to turn up for face-to-face peace talks in Istanbul as direct negotiations erupted in accusations that Russia made "unacceptable demands.

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.
