Ukraine launched one of its largest long-range drone operations against Russia, targeting sites around Moscow, including the Moscow oil refinery in the Kapotnya district. Russian authorities said air defenses intercepted hundreds of drones during the overnight assault, while several reportedly reached their targets inside the Moscow region. The attack comes amid escalating cross-border strikes between Kyiv and Moscow, renewed concerns over Russia's energy infrastructure, and growing uncertainty over how the Kremlin may respond. The strikes followed recent discussions among G7 leaders on support for Ukraine and have renewed attention on the broader geopolitical and energy market implications of the war.
