Elon Musk acknowledged Saturday that SpaceX had restricted its Starlink satellite internet service in Ukraine, disrupting communications and military operations that Ukrainian forces rely on in their war against Russia.

Ukrainian President Volodymyr Zelenskyy said service had returned to its previous speeds after restrictions affected frontline operations for more than a week. In a post on X, Zelenskyy said restoration began overnight, and connectivity had improved by Saturday morning, helping military logistics and defenses against Russian jet-powered Shahed drones.

Musk said the restrictions followed what he described as violations of Starlink’s terms of service by Ukrainian forces. He argued that the civilian satellite network was not intended to support offensive drone strikes.

“Using Starlink, a civilian commercial service, for offensive drone strikes to kill people has never been allowed, nor should it be,” Musk wrote. He added that Ukraine’s military had used the service for such attacks and that SpaceX had closed what he called a loophole the previous week.

However, questions remained over the restrictions affecting Starshield, SpaceX’s military-grade satellite service used for Ukrainian military communications and drone operations. Musk maintained that the U.S. government controlled changes to Starshield, while defending SpaceX’s broader role in supporting Ukraine since Russia launched its full-scale invasion in February 2022.

The restrictions prompted concern among Ukrainian officials and military commanders, who reported losing drones and experiencing disrupted missions. Ukrainian Defense Minister Yevhenii Khmara credited direct discussions and Zelenskyy’s diplomacy with Washington for the restoration, saying the outcome was important for frontline operations, drone activity, logistics and communications.

The dispute also unfolded amid tensions over who authorized the restrictions. President Donald Trump said he did not make the decision and argued Musk should not be blamed. Vice President JD Vance suggested there had been coordination with the White House, while Secretary of State Marco Rubio and Secretary of War Pete Hegseth denied that the administration was involved.

The restoration came as Washington pursued renewed diplomatic efforts to end the war. The Kremlin said Wednesday that Russia had agreed in principle to resume three-way negotiations with the United States and Ukraine next month. On Friday, Kyiv and Moscow also agreed to a localized ceasefire near Oleshky, a Russian-occupied town in the southern Kherson region, following mediation by First Lady Melania Trump.

The satellite dispute added another strain to relations between Kyiv and Washington, which had already faced friction over Trump’s reported deal with Moscow concerning Russian diesel imports, a move Ukraine viewed as a betrayal.

Fighting continued elsewhere. A missile attack on Lozova in Ukraine’s Kharkiv region killed one person and wounded two others, local officials said Saturday. Russian-installed authorities in occupied Crimea also reported power outages following overnight Ukrainian attacks.

Ukraine’s General Staff said its forces struck a chemical plant in Tolyatti, Russia, that produces materials used in rocket fuel. The city’s mayor, Ilya Sukhikh, confirmed that industrial facilities were damaged during an overnight attack.

Ukrainian forces also struck an electronics plant in Oryol that Ukraine’s military said manufactures components for Russian cruise and ballistic missiles. Local officials reported that three people were killed in Friday’s attack.

Ukrainian drones also reached Russia’s Omsk region in western Siberia, more than 1,242 miles from Ukraine’s border. Regional Gov. Vitaly Khotsenko said the drones had reached a northern industrial hub. Online retailer Ozon separately reported that a drone struck its logistics center in Omsk, though the company said no one was injured.
