Ukraine has launched its largest drone attack on the Moscow region, the mayor said, targeting the city’s main oil refinery and a residential building. According to Moscow Mayor Sergei Sobyanin, 450 drones heading for the capital had been shot down in what he described as ‘the most massive’ attack.

Key Targets Hit in Moscow Region

Regional governor Andrei Vorobyev stated at least two people were killed and 20 injured in the attack. A 44-year-old woman was killed in Sofyino after a drone struck a three-storey residential building. Another five people, including two children, were injured. In the Orekhovo-Zuevo district, an elderly man died when a private house was hit.

Ukrainian President Volodymyr Zelensky confirmed Kyiv had hit a ‘key’ Russian oil facility and a logistics site in the region with drones and missiles, representing ‘billions of dollars that sustain the war machine.’ The site supplies more than a third of the Moscow region’s fuel, according to Ukraine’s defence ministry, with some of its petrol, diesel, and aviation fuel used by Russia’s military.

Impact on Civilian Infrastructure and Election

Mayor Sobyanin said a drone had struck a building near one of the capital’s boulevards and the oil refinery, where Ukrainian military officials said three key units had been damaged. The mayor also suggested the attack was an attempt to disrupt Russia’s parliamentary election, which was in its third day on Sunday. The vote is tightly controlled by the Kremlin and has been dismissed by critics as neither free, fair, nor transparent.

Meanwhile, Russian state media reported that an election official was among two people killed by a drone attack on a bus in a Moscow-controlled part of Kherson, citing the head of Russia’s election commission. In the Kyiv and Sumy regions, nine people, including three children, were killed in Russian attacks on Saturday.

Regional head Tymur Tkachenko said a mother and her two small children, a boy and a girl, were killed in a Russian attack in the city of Fastiv on Saturday. A child injured in a separate attack in Vyshhorod, north of Kyiv, also died in hospital. In the north-eastern Sumy region, four people were killed when a Russian drone hit the car they were travelling in, according to top local official Oleh Hryhorov.

Airport Disruptions and Continued Attacks

Moscow’s biggest airport, Sheremetyevo, warned passengers of ‘temporary restrictions’ overnight, while Vnukovo airport halted all arrivals and departures. Restrictions at both airports were lifted by Sunday morning, but each warned some flights may still be delayed. Russia also struck a monastery in the Kherson region with a drone on Saturday, Zelensky said, killing one member of the clergy and injuring four others.

Both Russia and Ukraine have continued to hit energy infrastructure targets in the past week, despite US President Donald Trump claiming on social media that the two sides had agreed not to do so. Trump signed a sanctions bill on Friday that targets Russia’s economy by implementing tariffs on the biggest buyers of the country’s oil and gas, including China and India. The US legislation gives the president powers to impose 100% tariffs on major purchasers of Russian energy.

Russian President Vladimir Putin launched a full-scale invasion of Ukraine in February 2022.
