Ukraine launched a major drone attack that set fire to the Kapotnya oil refinery near the Kremlin and disrupted Moscow's commercial flights.

The strike represents the largest assault on the Russian capital since the conflict began. By targeting critical energy infrastructure and disrupting the airspace of the nation's capital, Ukraine is demonstrating an increased capability to penetrate deep into Russian territory.

The overnight operation into Thursday targeted nine Russian regions, including Moscow [1]. The attack specifically hit the Kapotnya oil refinery, which is located in proximity to the Kremlin [2]. This event marks the second time the Moscow oil refinery has been hit within a single week [3].

In response to the aerial assault, Moscow authorities suspended or disrupted commercial flights at local airports [4]. The shutdowns were a direct result of the drone activity as Russian defense systems attempted to intercept the incoming aircraft [4].

Ukraine said the strike was part of its broader campaign against Russian targets [5]. The operation focused on degrading the logistics and energy production capabilities that support the Russian military effort [5].

Russian officials have not provided a full accounting of the damage to the refinery, but the fires were visible from the surrounding areas [2]. The disruption to air travel caused significant delays for passengers and commercial cargo operations across the city [6].

The strike represents the largest assault on the Russian capital since the conflict began.

This escalation indicates a strategic shift by Ukraine to bring the costs of the war directly to the Russian capital. By repeatedly targeting the Kapotnya refinery and disrupting the aviation hub of Moscow, Ukraine is testing Russian air defenses and attempting to create economic instability through energy disruption and logistical chaos.
