Russian drone and missile strikes killed at least 22 people and wounded more than 80 across Ukraine, as President Volodymyr Zelenskyy blasted Moscow’s “absolute cynicism."

Russian drone and missile strikes targeting Ukraine’s power grid during the night killed at least five people and wounded 39 others, Ukrainian authorities said Tuesday, less than a day before Kyiv said that it would enact a ceasefire and three days before Moscow promised its own pause in hostilities.

Russia's Defense Ministry has declared a unilateral ceasefire in Ukraine to mark Victory Day, commemorating the defeat of Nazi Germany in World War II.

​On May 4, Russia's attacks killed at least 14 people, Ukrainian officials reported; close to 60 others were wounded. The heaviest toll was reported in Merefa, a town near Kharkiv, where a Russian strike killed seven civilians and injured 32, destroying shops and setting cars ablaze.

Russia declared a unilateral ceasefire in Ukraine for Friday and Saturday to mark the defeat of Nazi Germany in World War II, but threatened to strike back at Kyiv if it tries to disrupt festivities.

Ukraine has launched a wave of strikes against Russia’s oil export infrastructure, hitting a key loading port on the Baltic Sea and three tankers that Ukraine alleges were illegally used to transport Russian crude.

Strikes came hours before deadline for Kyiv ceasefire proposal and were one of the worst wave of attacks this year
