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.

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

It is 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.
