Ukraine launched one of its largest drone attacks against Russia, targeting a major oil refinery in Moscow and other energy facilities, highlighting the vulnerability of strategic infrastructure deep inside Russia.

Russia’s defense ministry reported intercepting over 150 drones across 15 regions, with some hitting key energy sites, including a Gazprom refinery and a power station in Tver.

Videos showed explosions at the refinery, but officials reported no casualties. Kyiv did not comment on the attacks.

These strikes are part of Ukraine’s intensified campaign to disrupt Russia’s military fuel supply and damage its energy infrastructure.

Ukrainian President Volodymyr Zelensky defended the attacks, citing Russian aggression against Ukrainian cities, the Wall Street Journal has reported.

Kyiv has increasingly relied on homegrown drones to strike targets within Russia, as it seeks permission from the U.S. to use longer-range missiles like ATACMS to further pressure Russia.
