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.

Ukrainian President Volodymyr Zelenskyy called on Saturday for stronger sanctions on Moscow after a Russian drone killed nine bus passengers in northeastern Ukraine just hours after the two countries held their first peace talks in three years of war.
