Ukraine sent its largest drone swarm at Moscow in more than a year overnight, killing at least four people and rattling infrastructure across the Russian capital’s outskirts.

What happened

Russia’s defense ministry reported that 556 Ukrainian drones were intercepted or otherwise engaged across 14 regions, including Crimea and areas over the Black Sea. Of those, 81 were directed at the Moscow region alone.

Three of the four confirmed deaths occurred in the Moscow region. A fourth person was killed in Belgorod, the border region that has absorbed consistent Ukrainian strikes throughout the war. At least 12 people were reported injured.

Moscow Mayor Sergei Sobyanin confirmed that strikes landed near an oil refinery, causing damage to surrounding residential areas. Sobyanin claimed the refinery itself sustained no critical damage.
