Russia's Defense Ministry reports that air defenses shot down 347 Ukrainian drones overnight. This major attack comes after Moscow rejected Kyiv’s ceasefire earlier in the week. Drones were destroyed in over 20 Russian regions, including Moscow. The attack is Ukraine’s second-biggest aerial assault since Russia's invasion over four years ago. It occurred ahead of Russia’s Victory Day celebrations, marking the defeat of Nazi Germany in World War II. Tensions have risen as the celebrations approach, with Russia scaling back its traditional military parade due to security concerns. Authorities blame Ukraine for the heightened security measures.
