Russia has launched one of its largest aerial assaults on Ukraine in months, targeting Kyiv overnight into Monday.

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.

Russia has advanced around Pokrovsk for many months, but has so far failed to entirely encircle or seize control of the city.

The barrage of exploding drones and missiles appeared to be the most intense attack since President Trump announced a plan to get more weapons for Kyiv.
