Five people have been killed in overnight strikes in Russia and Ukraine, as the two sides continue to trade drone attacks. Ukrainian officials said on Saturday that more than 200 drones and almost 30 missiles were fired by Russia, with most targeting Dnipropetrovsk where three people died.

Ukraine’s once-formidable advantage in drone warfare appears to be eroding along parts of the front line. This degradation extends far beyond the immediate front—more Russian drones now prowl for targets up to 25 kilometers (roughly 16 miles) behind the contact line, and they have been hitting their targets more effectively.

Russian strikes across Ukraine killed at least 12 civilians and injured more than 120 others. In the eastern Donetsk oblast, or province, systematic shelling and glide bombs killed six non-combatants and wounded 44 others.
