After being accused of violating the last short-term truce, President Vladimir Putin says Russia will halt its war in Ukraine for three days to mark 80 years since the defeat of Nazi Germany.

The Kremlin said on Monday that President Vladimir V. Putin had ordered a three-day cease-fire in Ukraine next month, the second time in two weeks that Russia’s leader has promised a temporary pause in the fighting as President Trump shows growing impatience with his refusal to stop the war.

It’s the second time in less than two weeks that the Russian president has called a halt to fighting without committing to a long-term end to the war.
