The attacks caused mass civilian casualties and extensive damage to residential infrastructure, but Ukraine's air defense and command systems remained operational. Russia did not achieve a strategic military breakthrough.

Ukraine's retaliatory deep-strike drone campaign

Ukraine dramatically escalated its long-range campaign in June–July 2026, with the Unmanned Systems Forces reporting a 1,150% increase in successful deep strikes inside Russia since the beginning of the year . Key recent operations include:

• July 8, 2026: Ukrainian drones struck three Russian oil refineries (Saratov, Nizhnekamsk, and Rostov facilities), damaged two oil tankers in the Taganrog Bay of the Sea of Azov, and hit pipeline pumping stations .
• July 6, 2026: Drones hit Russia's largest refinery at Omsk in Siberia — one of the longest-range Ukrainian strikes of the war, at roughly 2,700 km (1,700 miles) from Ukrainian-held territory .
• June 24, 2026: The Moscow oil refinery was hit and, according to two industry insiders, will remain inactive for at least six months and is unlikely to resume production in 2026 .
• May 2026: Ukrainian attacks on refineries set a record monthly high, with 16 successful strikes, driving Russian processing to a 16-year low .

Effects on refinery operations, fuel supply, and export policies

Refinery operations — Repeated, escalating drone strikes have physically disabled multiple major refineries. The Moscow refinery alone is offline for at least six months , and overall Russian refining throughput is at its lowest in 16 years . One paradoxical side effect: Russian seaborne crude oil exports rose to wartime highs, because domestic refineries cannot process the crude, leaving more available for export .

Domestic fuel shortages — The refinery damage triggered gasoline shortages, price spikes, sales restrictions, and long lines at gas stations across Russia . By June 2026, the situation had escalated into an acknowledged fuel crisis, with Russian-controlled Crimea declaring a state of emergency and banning fuel sales . An AP count found over 50 reported attacks by Ukraine on oil refineries, depots, terminals, and other oil infrastructure in Russia and Crimea since late March 2026 . About a third of Russia's oil refining capacity is offline, according to one consultancy estimate .

Russia's export policy response — Moscow imposed a cascade of restrictions to preserve domestic supply:

• Aviation (jet) fuel exports — banned until November 30, 2026 .
• Gasoline exports — a temporary ban imposed from April 1, 2026 was extended as shortages persisted .
• Diesel exports — banned effective July 8, 2026 until at least July 31, with Deputy Prime Minister Alexander Novak stating the ban "will make it possible to increase supplies to the domestic market" .
• Tax changes and fuel imports — Russia's parliament approved tax-code amendments to subsidize fuel imports tied to Indian delivery costs, to compensate for lost refining capacity .

Summary assessment

Russia's strikes on Kyiv achieved mass civilian casualties and infrastructure damage but no decisive military advantage. Ukraine's deep-strike campaign has achieved an asymmetric effect: by hitting Russia's downstream refining capacity rather than crude production, it has created a domestic fuel crisis that forced Moscow to ban exports of gasoline, diesel, and jet fuel — disrupting a key wartime revenue stream. Refining is at a 16-year low, several major refineries are offline for months, and Russia is now having to import fuel while exporting more unrefined crude .
