Moscow's oil refinery is expected to remain out of operation for at least six months after sustaining significant damage in Ukrainian drone attacks, two industry sources said on Wednesday, The Caspian Post reports, citing Reuters.

Situated on the southern edge of the Russian capital, the refinery is the main supplier of fuel to the Moscow region. It was struck twice by Ukrainian drones earlier this month, forcing the facility to suspend its operations.

"The repairs will take no less than six months," one of the sources said, referring to the extent of the damage at the Moscow refinery.

Gazprom Neft, which operates the facility, did not respond to a request for comment.

Ukraine has intensified its long-range drone attacks on Russian energy infrastructure in recent months. At the same time, Russia has continued launching missile strikes against energy and defence-related targets in and around Ukrainian cities.

The Ukrainian attacks have put a substantial portion of Russia's oil refining capacity out of service, leading to shortages of petroleum products, rising fuel prices and long lines at filling stations in many regions spanning the country's 11 time zones.

The Moscow refinery, which has been targeted on several occasions, processed 11.6 million metric tons of oil in 2024, according to the latest available data. The plant produced 2.9 million tons of gasoline and 3.2 million tons of diesel during that period.

Amid growing pressure on fuel supplies, Deputy Prime Minister Alexander Novak said on Tuesday that Russia is considering imposing a ban on diesel exports. Meanwhile, the Vedomosti newspaper reported that authorities are also considering fuel imports to ease shortages, particularly in Crimea, where gasoline sales to the public have been suspended.
