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.

Kyiv accused the Kremlin of introducing new “unacceptable demands” to withdraw Ukrainian forces from huge swaths of territory, collapsing the talks.

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.
