Ukraine's defense systems apparently shot down at least 40 drones launched by the Russian military. Two people were killed in the serious attack, others were injured.

Russia also claims to have intercepted several drones that flew towards the Ilski oil refinery in Russia's Krasnodar region. The attacks at dawn took place on the last Sunday of May, when the capital celebrates Kiev Day, the anniversary of its official foundation 1541 years ago. The counteroffensive to recapture Russian-occupied territories, which has been expected for weeks, continues.
