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.

Russian President Vladimir Putin on Monday declared a three-day ceasefire in May in the war with Ukraine to mark the 80th anniversary of the victory of the Soviet Union and its allies in World War Two.
