Ukrainian forces conducted a coordinated overnight drone campaign targeting Russian military and energy infrastructure in occupied Crimea and Krasnodar Krai on June 21, 2026. The strikes hit the oil transshipment complex at the Port of Kavkaz and the TES-Terminal-1 oil depot in Kerch, both critical for supplying fuel to Russian forces in southern Ukraine. Ukrainian Unmanned Systems Forces, the Security Service (SBU), and Special Operations Forces were involved in the operation, which also disabled multiple S-400 and Pantsir air defense systems and radar installations near the Kerch Strait Bridge. Geolocated footage confirmed fires at key sites and damaged ferries, disrupting Russia’s primary maritime supply route to Crimea.

In response, Russian occupation authorities imposed emergency fuel restrictions across Crimea, halting sales at gas stations and suspending ferry operations. Sevastopol’s leadership also canceled public events and reduced public transport hours. These measures reflect growing strain on logistics as Ukraine intensifies its intermediate-range strike campaign against rear-area infrastructure. The broader goal appears to be degrading Russia’s ability to sustain offensive operations by targeting ground lines of communication and energy supplies.

Meanwhile, Russian forces continued limited offensives in eastern Ukraine without making advances, while Ukraine countered infiltration attempts near Pokrovsk and Kostyantynivka. In southern Zaporizhzhia, Ukrainian strikes hit Russian logistics hubs and drone control points. The conflict remains fluid, with both sides relying heavily on drone warfare and rear-area targeting to shape battlefield conditions.
