Russia reported one of the largest Ukrainian drone attacks on its capital since the beginning of the war, with at least two people killed, hundreds evacuated and a major oil refinery damaged. The overnight assault coincided with the final day of Russia’s parliamentary elections, prompting Moscow to accuse Kyiv of attempting to disrupt the vote.

MOSCOW, September 20, 2026. A massive overnight Ukrainian drone attack struck Moscow and its surrounding region on Sunday, killing at least two people, damaging a major oil refinery and forcing hundreds of residents to evacuate their homes, according to Russian authorities.
The attack took place as Russians headed to polling stations for the final day of the country’s parliamentary elections, the first since Moscow launched its full-scale invasion of Ukraine in February 2022.
Moscow regional governor Andrey Vorobyov said the region had experienced an extensive wave of drone strikes during the night, with residential areas and infrastructure affected.
Around 400 people were evacuated from an apartment building as emergency services responded to the attacks.
Moscow Mayor Sergei Sobyanin described the operation as the largest drone assault directed at the Russian capital.
According to Sobyanin, Russian air defence systems intercepted more than 1,600 drones, including approximately 450 heading towards Moscow.
These figures were reported by Russian officials and could not be independently verified.
Moscow accuses Ukraine of attempting to disrupt elections
Russian authorities linked the timing of the attack to the parliamentary elections, which began on Friday and concluded on Sunday.
Sobyanin accused Ukraine of deliberately planning the operation to interfere with the electoral process.
In a statement published on Telegram, the mayor said Russian air defence forces had repelled the attack and that the alleged attempt to disrupt the elections had failed.
The Kremlin has presented the parliamentary vote as an opportunity for Russians to demonstrate their support for the country’s political leadership and its military campaign in Ukraine.
President Vladimir Putin urged citizens to participate in the elections in a televised address before voting began.
He said public participation would demonstrate national unity and support for Russian soldiers fighting in Ukraine.
The ruling United Russia party entered the election holding a dominant position in the State Duma, Russia’s lower house of parliament.
The vote is taking place against the backdrop of more than four years of war, growing pressure on Russia’s economy and continuing Ukrainian attacks on infrastructure inside Russian territory.
Ukraine confirms strikes on Russian oil and logistics infrastructure
Ukrainian President Volodymyr Zelenskyy confirmed that Ukrainian forces had carried out long-range attacks against infrastructure in and around Moscow.
In a statement published on X, Zelenskyy said the operation had struck an important Russian oil industry facility and a logistics installation.
The Ukrainian president described the attacks as having a significant impact on infrastructure supporting Russia’s war effort.
The reported damage to an oil refinery is particularly important because Russia’s energy industry provides revenue for the state and fuel for its domestic economy and military operations.
Ukraine has increasingly targeted Russian oil refineries, fuel storage facilities and logistical infrastructure as part of its campaign to weaken Moscow’s capacity to sustain the war.
Such attacks also demonstrate Ukraine’s growing ability to conduct long-range operations against targets deep inside Russian territory.
The full extent of the damage caused by Sunday’s strikes remained unclear.
Neither the Russian nor Ukrainian accounts provided a comprehensive, independently verified assessment of the facilities affected.
Drone warfare brings the conflict closer to Moscow
The latest attack highlights the expanding geographical reach of the war and the increasing importance of unmanned aerial systems.
Moscow and its surrounding region have experienced repeated Ukrainian drone attacks, but the scale reported by Russian authorities on Sunday would represent a significant escalation.
The reported use of hundreds of drones directed towards the capital also illustrates the growing pressure on Russian air defence systems, which must protect military installations, energy facilities, transport networks and densely populated urban areas.
For Moscow residents, the overnight attack brought renewed disruption as emergency services responded to damaged buildings and authorities evacuated people from potentially dangerous locations.
The reported deaths also underline the risks posed to civilians as both sides continue to conduct long-range attacks.
While Ukraine has concentrated many of its strikes on infrastructure linked to Russia’s military and energy sectors, Russian officials have repeatedly reported civilian casualties and damage to residential buildings during drone operations.
Russian attacks on Kyiv region kill civilians
The Ukrainian assault followed deadly Russian attacks on the Kyiv region over the weekend.
Ukrainian officials reported that three children and a woman had been killed in Russian strikes on the Vyshgorod district on Saturday.
On Sunday, regional authorities said another child who had been injured in the attack had died in hospital.
The reported deaths highlight the continuing civilian toll of the conflict as Russia maintains its missile and drone campaign against Ukrainian cities and infrastructure.
Ukraine has repeatedly called for additional air defence systems and interceptor missiles to protect its population from Russian aerial attacks.
Both countries have expanded their use of long-range drones, creating new challenges for air defence networks and increasing the vulnerability of infrastructure far from the front lines.
A war increasingly fought beyond the front lines
The latest developments illustrate how the conflict has evolved beyond conventional military operations along the front.
Long-range drones and missiles have become central instruments in both countries’ efforts to disrupt military logistics, damage critical infrastructure and place pressure on their adversary.
For Ukraine, attacks on Russian oil facilities and logistical installations form part of a broader effort to undermine the resources available to Moscow’s military campaign.
For Russia, continued strikes against Ukrainian cities and infrastructure remain a major component of its military operations.
The timing of Sunday’s attack also places the war at the centre of Russia’s parliamentary election weekend, although Moscow’s assertion that the operation was specifically intended to disrupt voting has not been independently established.
As Russian authorities assess the damage around Moscow and election officials complete the parliamentary vote, the latest exchange of attacks demonstrates the continuing intensity of a conflict that has entered its fifth year.
With neither side showing signs of ending its long-range military operations, the protection of civilian populations and critical infrastructure remains an increasingly urgent challenge for both countries.
