Five people have been injured in the Ukrainian capital Kyiv as Russia launches a fresh wave of drone strikes across the country.
Air raid sirens and explosions were heard in Kyiv and in the western city of Odesa, officials have said, just a day before Russia's Victory Day on Tuesday, May 9.
The annual holiday commemorates the Soviet Union's victory over Nazi Germany during World War Two and will include a parade of the country's military firepower.
