Ukraine has abandoned a short-lived truce on energy-related targets and resumed strikes on Russian oil refineries, a move that adds fresh strain to Kyiv’s relations with Washington. Ukrainian drones hit a refinery in Russia’s Ryazan region early on Thursday, October 15, 2026, starting a fire at the facility about 300 kilometers, or 180 miles, southeast of Moscow, according to Russia’s Defense Ministry and the regional governor. A senior Ukrainian official confirmed the attack.

The strike came hours after President Volodymyr Zelenskyy said the truce, which Moscow had spurned, was over. The truce followed President Donald Trump’s call on Sunday for both sides to stop attacking energy infrastructure. Zelenskyy says Ukraine went along with it, yet Russian bombardment of Ukrainian energy sites continued. In an interview with the Financial Times, he said Ukraine’s patience had run out and that attacks on Russian refineries would resume. The Kremlin’s position is different: spokesman Dmitry Peskov said Ukraine never stopped hitting refineries. Neither side’s claims could be independently verified.

Zelenskyy’s frustration extends to Washington. He says that in recent days Ukraine was denied its usual Western intelligence on Russian ballistic missile strikes and that limits were placed on its use of U.S.-made Starlink terminals, both vital to Ukrainian defense and drone operations. Trump has said the United States has not stopped sharing intelligence with Ukraine. A Ukrainian official said Kyiv has received no explanation from SpaceX or the Pentagon about the Starlink slowdown, and the Pentagon has not answered questions from the Associated Press.

Another flashpoint is a deal Trump struck with Russian President Vladimir Putin to import Russian diesel, despite international efforts to sanction Russia and isolate Putin diplomatically. Zelenskyy criticized the agreement, arguing it lets Russia continue its full-scale invasion, which began more than 4½ years ago, and said Russia escalated its attacks after receiving sanctions relief. In a separate interview with British broadcaster Piers Morgan, he said he felt betrayed by the diesel deal, the energy ceasefire announcement and the Starlink restrictions, adding that Ukraine is losing a strong partner. Russian Foreign Minister Sergey Lavrov described the strikes as a blunt provocation aimed at Trump.

The overnight fighting was intense. Zelenskyy said Russia launched more than 850 drones at Ukraine between midnight and Thursday morning, hitting 15 regions. Ukraine’s air force said it stopped 536 of them, though impacts were recorded at 31 locations. A Russian drone attack lasting more than 10 hours in the Kirovohrad region killed three people and injured six, Ukraine’s Emergency Services said. Zelenskyy also said a Ukrainian missile destroyed six warplanes at an airfield in southwestern Russia that were used to launch glide bombs. Russia’s Defense Ministry said its air defenses downed 166 Ukrainian drones overnight and that its forces hit two vessels carrying military cargo.

Kyiv is now looking to Europe. Zelenskyy traveled to Brussels for talks with EU leaders attending a two-day summit and planned to meet NATO Secretary-General Mark Rutte, French President Emmanuel Macron and the prime ministers of Poland, Denmark and Belgium. A day earlier he visited London, where he won pledges of more help from British Prime Minister Andy Burnham. EU foreign policy chief Kaja Kallas said Europe takes a different approach to the war, arguing that the aggressor should be pressured to stop rather than the victim pushed to surrender.

With U.S.-led peace efforts having made no progress, the collapse of the energy truce leaves the war’s diplomatic track uncertain and puts the focus on Europe’s response.
