Ukraine will resume strikes on Russian oil refineries, President Volodymyr Zelensky stated, accusing the United States of withdrawing crucial support and intelligence sharing.

Zelensky said he had paused such attacks for three days at Washington's request, while Russia continued to target Ukrainian energy infrastructure. "We're done," he told the Financial Times, signaling an end to the self-imposed moratorium.

The Ukrainian president further alleged that the US had withheld intelligence-sharing on Russian strikes to pressure Kyiv into halting refinery attacks. He also claimed that restrictions on Starlink satellite services, vital for Ukraine's military, were deliberate actions rather than technical glitches.

These developments come as Russia reported an attempted large-scale attack on an oil refinery south of Moscow early Thursday, with its defense ministry stating that four missiles and dozens of drones were intercepted, causing a fire from falling debris in Ryazan. Zelensky countered by stating that dozens of Ukrainian cities had come under Russian attack in the preceding day.

Zelensky had previously indicated a willingness to observe an "energy ceasefire" proposed by US President Donald Trump, provided Moscow also adhered to it. However, he accused Russia of violating the proposed truce within hours of its announcement, with subsequent strikes leaving hundreds of thousands of Ukrainians without power. The Kremlin did not confirm its agreement to the deal.

Speaking about the US, Zelensky expressed feeling betrayed, particularly after Washington appeared to withdraw key elements of its support. He revealed that US officials had warned Ukraine that continued refinery strikes would result in the blocking of intelligence. Ukraine's military relies heavily on US early-warning alerts for air defense and Starlink internet for drone operations and airspace protection.

Following an unexpected restriction on drone flight speeds while maintaining Starlink connectivity, initial suggestions pointed to a technical issue. However, Starlink owner Elon Musk seemingly indicated it was due to the Trump administration's actions, a claim Trump has denied. Zelensky asserted to the FT that the restriction was "the will," not a technical problem.

Sources within Ukraine's Ministry of Defence later reported that the military-focused version of Starlink, Starshield, had its mobile operations restored, though officials were still investigating the cause of the previous day's disruptions. Zelensky's remarks were made during a visit to London, where he met with UK Prime Minister Andy Burnham, who announced accelerated delivery of lightweight multirole missiles to Kyiv. European leaders have also expressed solidarity with Ukraine.
