In a significant escalation of its campaign against Russian infrastructure, Ukraine launched a series of drone attacks on oil facilities in Russia over the weekend, with pro-Russian bloggers warning that repairs will be slow and costly due to sanctions and air defence failures. The strikes come as Ukrainian President Volodymyr Zelenskyy continues his tour of Middle Eastern countries, voicing concerns that a prolonged US-Israeli war on Iran could divert American support away from Kyiv, undermining Ukraine's defence efforts.
Drone Assaults on Russian Oil Infrastructure
According to online channels monitoring the conflict, Ukrainian drones attacked the Sheskharis oil terminal at the Black Sea port of Novorossiysk in Russia's Krasnodar region overnight on Sunday. Footage circulated online purported to show a large fire at the port, with additional strikes reported on oil facilities in other regions. Russia's military claimed early on Monday that air defence units downed 148 Ukrainian drones over a three-hour period, and nearly half a million households experienced blackouts due to air attacks.
On Sunday evening, drones killed one person in Russia's border region of Belgorod and struck an apartment building in Novorossiysk, according to Russian authorities. The Institute for the Study of War assessed that Ukraine has intensified its attacks on Russia's oil infrastructure over the past two weeks, focusing on critical export hubs like the Baltic Sea port and facilities in Leningrad oblast.
Strategic Impact and Russian Response
The ISW noted that a claimed strike on Primorsk overnight on 4-5 April marked the third attack on the port within two weeks. Ukrainian forces also reportedly struck the Lukoil-Nizhegorodnefteorgsintez refinery in Kstovo, Nizhny Novgorod oblast, approximately 1,000km from Primorsk, starting a fire. Geolocated footage showed Russian air defences responding, while fires were detected by Nasa's Firms global satellite fire monitoring system. The oblast governor acknowledged the attacks and damage to oil company facilities.
Russian military bloggers have complained that the damage inflicted on Russia's oil export capacity will be costly and time-consuming to repair, with damaged or lost ships difficult to replace due to parts sanctions and air defence failures. In Crimea, occupied by Russia since 2014, the governor of Sevastopol reported four drone attacks throughout Sunday, with seven drones downed in the latest wave.
Humanitarian and Regional Fallout
A Russian strike on Odesa city killed three people, including a child, and hospitalised two with serious injuries, a Ukrainian military official said on Monday. In Russian-occupied Donetsk region, the head of the Russia-installed government, Andrei Chertkov, stated that repair crews restored power to Donetsk and Makiivka after Ukrainian attacks, with outages also reported in Russian-held areas of Zaporizhzhia region.
Additionally, a Russia-installed official claimed that a cargo ship carrying wheat sank in the Sea of Azov after coming under attack from Ukrainian drones on Friday, resulting in one death and two missing persons. Ukraine denies targeting such vessels unless there is a valid military objective.
Zelenskyy's Middle East Diplomacy and Concerns
During his tour, Zelenskyy met with Syrian President Ahmed al-Sharaa in Damascus, where Ukraine and Syria pledged greater security cooperation. In an exclusive interview with the Associated Press in Istanbul, Zelenskyy expressed fear that a long war between the US and Israel against Iran could reduce American support for Ukraine, as Washington's global priorities shift. He highlighted that Ukraine desperately needs more Patriot air defence missiles to counter Russia's daily barrages, but faces reduced deliveries.
Zelenskyy warned that Russia benefits economically from the Iran war, citing a limited easing of American sanctions on Russian oil. Surging oil prices, driven by Iran's closure of the Strait of Hormuz, boost Kremlin revenues and strengthen Moscow's capacity to sustain its war effort. In response, Ukraine has stepped up attacks on Russian oil production and export infrastructure.
Proposals for Regional Cooperation
Zelenskyy offered to share Ukraine's experience and technology, including interceptor drones and sea drones produced with American and European funding, with Gulf Arab countries targeted by Iran. In return, he suggested these countries could assist Ukraine with anti-ballistic missiles. He also positioned Ukraine as a potential partner in safeguarding global trade routes, offering help in reopening the Strait of Hormuz by sharing expertise from securing maritime corridors in the Black Sea.
As the conflict enters day 1,503, these developments underscore Ukraine's strategic shift towards targeting Russian economic assets while navigating complex international dynamics that could impact its military support.
