Ukraine launched what Moscow officials describe as the largest drone attack in the city’s history on September 20, 2026, targeting a major oil refinery and residential buildings. Moscow Mayor Sergei Sobyanin reported that 450 drones were intercepted, while Ukrainian President Volodymyr Zelensky confirmed the strikes hit a “critical” petroleum facility and a logistics base to disrupt Russian military funding and supplies, according to BBC News.
The assault coincided with the third day of Russia’s parliamentary elections. Mayor Sobyanin stated the attack was an “attempt to disrupt” the voting process, which critics have described as being strictly controlled by the Kremlin, according to BBC News.
–>Moscow refinery and residential damage
The strikes hit a primary oil refinery in the Moscow region, with Ukrainian military officials reporting that three critical production units were damaged. The Ukrainian Ministry of Defense stated the facility provides more than one-third of the fuel for the Moscow region, including gasoline, diesel, and aviation fuel used by the Russian military, according to BBC News.
Regional Governor Andrei Vorobyev reported two deaths and 20 injuries resulting from the attacks. In Sofyino, a drone hit a three-story residential building, killing a 44-year-old woman and injuring five others, including two children. A separate strike on a private residence in the Orekhovo-Zuevo district killed an elderly man, according to BBC News.
The attack also caused significant disruptions to Moscow’s transportation hubs. Vnukovo Airport suspended all incoming and outgoing flights, and Sheremetyevo Airport implemented “temporary restrictions” for passengers. Both airports lifted these measures by Sunday morning, though officials warned of potential flight delays, according to BBC News.
–>Russian strikes in Ukraine
Russia conducted simultaneous attacks across Ukraine on September 20 and 21, resulting in at least 13 deaths. In the Sumy region, official Oleh Hryhorov reported that a Russian drone struck a vehicle, killing four people. In the Kherson region, President Zelensky stated a drone attack on a monastery killed one cleric and injured four others, according to BBC News.
Further casualties were reported in the Kyiv region. Regional official Tymur Tkachenko stated a strike in the city of Fastiv killed a mother and her two young children. An additional child died in a hospital after being injured in an attack in Vyshhorod, according to BBC News.
–>Energy infrastructure and international sanctions
Both nations have increased targeting of energy production, transport facilities, and logistics hubs. President Zelensky described the Moscow strikes as hitting “billion-dollar assets” that maintain the Russian war machine, according to BBC News.
These escalations follow a Friday action by U.S. President Donald Trump, who signed a sanctions bill targeting the Russian economy. The legislation authorizes the U.S. president to impose 100% tariffs on the largest buyers of Russian oil and gas, including China and India, according to BBC News.
The strikes occurred despite previous claims by President Trump on social media that both parties had agreed to stop attacking energy infrastructure, according to BBC News.
Election-related casualties
The conflict extended into the election administration. Russian official media reported that a bus in the Moscow-controlled Kherson region of Ukraine was hit by a drone, killing two people. One of the deceased was identified as an election worker, according to the Russian Election Commission via BBC News.
