Russian President Vladimir Putin on Monday declared a unilateral three-day ceasefire in Ukraine next month, a move met with skepticism by Ukrainian officials who demanded the Kremlin leader immediately accept a longer truce proposal from the United States that he has so far rejected.

Russian President Vladimir Putin declared a three-day ceasefire in the war with Ukraine next month to celebrate the Soviet Union’s victory over Nazi Germany during World War II.

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.
