Ukraine's Defense Ministry estimates that long-range strikes have knocked out more than half of Russia's oil refining capacity, up from the 45% the General Staff cited earlier.
On October 4, Ukraine's Ministry of Defense reported that long-range strikes by the Security and Defense Forces have disabled more than 51% of Russia's oil refining capacity. Defense Minister Yevhen Khmara said the figure rests on assessments by intelligence and analysts of the General Staff and the ministry.

The ministry's report lists recent strikes on the Moscow, Yaroslavl, Perm, Ilsky, Saratov and Syzran refineries, as well as the Kirishi facility and the refinery in Ust-Luga. The illustrative photo above is not tied to any specific listed site. Khmara noted that the results of such operations are not always visible immediately, but the effect accumulates.
The estimate is higher than the 45% reported by the General Staff on September 21. The minister called it a significant blow to the enemy's economy and its ability to supply its troops. The ministry added that this year Ukraine has tripled production and procurement of long-range strike drones and plans to expand further.
President Zelensky recently said Ukraine will intensify strikes on Russian refineries in response to Russia's massive attacks on civilian infrastructure. Meanwhile, NGO Volunteers Support Ukraine keeps helping people affected by the war, within its capacity.
