Ukraine launches record drone attack on Russia, killing at least four

More than 500 Ukrainian drones struck Russia in a single overnight barrage that killed at least four people and left Moscow’s airports repeatedly disrupted, underscoring how the war is shifting toward mass, lower-cost attacks designed to overwhelm air defenses.

Russian authorities said air defenses intercepted drones across 14 regions and annexed Crimea. Russia’s defence ministry said 556 drones were downed overnight and into the morning, making it the largest assault on Moscow in more than a year. At least three people were killed in the Moscow region, and one more died in Belgorod region. Other reporting said 12 people were injured in the Moscow region.

In the Moscow area, the attack hit residential neighborhoods as well as critical infrastructure. Moscow Mayor Sergei Sobyanin said the “technology” of the Moscow oil refinery was not damaged, although three houses were damaged in the attack. The city’s four airports were disrupted multiple times since late Saturday, adding to the strain on transportation and emergency services around the capital. One target was Sheremetyevo Airport, where operations were among those affected.

The scale of the strike makes it stand out from earlier drone campaigns. A May 7 Ukrainian drone attack on Moscow had already been described as a major incident, with dozens of drones intercepted. This latest barrage was far larger, and it arrived after renewed Russian strikes on Ukraine, sharpening the cycle of retaliation. The timing points to a war that is increasingly being fought through deep strikes rather than only on the front line.

That shift matters because drones are cheaper and easier to launch in volume than missiles, but they can still force Russia to spread out air defenses, protect airports and infrastructure, and absorb repeated disruption across a vast territory. The attack did not appear to knock out the Moscow oil refinery, yet it did show how vulnerable even the capital can be when dozens or hundreds of drones arrive at once.

For Ukraine, the barrage suggests a strategy built on pressure, tempo and saturation. Whether it changes the strategic balance is less clear. What is clear is that the scale of these attacks is rising, and Russia is being pushed to defend a wider map, with greater frequency and higher political cost.
