Ukraine drone travels 2,700 km to strike Russian refinery in 'longest-range attack of the war'

A Ukrainian drone has struck a Russian oil refinery deep inside Russian territory, more than 2,000 kilometers from the border.

Ukrainian forces struck the Omsk oil refinery — Russia's largest refining facility — with a drone Monday, according to Reuters and other outlets.

Russian regional authorities also confirmed the strike on the Omsk refinery.

The facility lies roughly 2,700 kilometers from Ukraine, deep in Russia's rear.

Reuters called the attack "one of the longest-range strikes by Ukraine since the war began."

The refinery, owned by Russian oil giant Gazprom Neft, processes about 460,000 barrels of crude oil per day.

Ukrainian forces also targeted oil refineries in Russia's Yaroslavl and Leningrad regions.

An oil products transshipment terminal in Crimea, a petroleum loading terminal in Vysotsk and a refinery in Kaluga region were also hit in Ukrainian drone strikes.

In the Sea of Azov, two vessels belonging to Russia's "shadow fleet" came under Ukrainian drone attack. According to the Ukrainian military, the ships were transporting about 7,000 tons of fuel from the Russian port of Taganrog to Crimea.

Ukraine's medium-range drones have also been drawing growing attention of late.

Kyiv has been deploying them to strike Russian supply lines with concentrated force.

"Kat," the call sign of a K-2 Brigade commander operating medium-range drones in Ukraine's Kharkiv region, told the AP on Monday that "our mission is to cut off Russian logistics." She added: "If you cut the supply lines, the frontline infantry gets no food, no ammunition. That's how we're exhausting them on every front."

As Ukrainian drones have increasingly zeroed in on supply routes, Russian logistics have come under serious strain. Crimea — effectively cut off from the Russian mainland and suffering fuel shortages and power outages — is frequently cited as a prime example.

Ukraine's medium-range drone units operate from concealed locations in ordinary civilian spaces.

Regular offices serve as command posts, and what appears to be a woodworking shop doubles as a drone assembly facility. The AP reported that pilots in civilian clothes sit before computer screens looking no different from office workers doing spreadsheet work.
