Ukraine launched its most significant drone assault on Moscow in over a year overnight, killing at least four people and damaging infrastructure on the Russian capital's outskirts.
Russia's defense ministry reported 556 Ukrainian drones were intercepted or engaged across 14 regions, including Crimea and the Black Sea. 81 of those 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, a border region that has faced consistent Ukrainian strikes. At least 12 people were reported injured.
Moscow Mayor Sergei Sobyanin confirmed strikes near an oil refinery, causing damage to nearby residential areas, but claimed the refinery itself sustained no critical damage.
President Zelensky framed the attack as retaliation for a significant Russian barrage that killed 24 Ukrainian civilians. He vowed to intensify strikes on Russian soil. Ukraine's air force reported that Russia simultaneously launched 287 attack drones at Ukrainian targets, intercepting 279.
The ongoing escalation raises the probability of tighter sanctions enforcement against Russia, potentially impacting cross-border financial activity and energy markets.
