Ukrainian drones strike Russia's largest oil refinery as Zelenskyy says Siberia is now within reach

Ukrainian drones struck one of Russia's largest oil refineries, according to reports. Kyiv said the attack demonstrates that its long-range strike capability has advanced markedly in recent months.

President Volodymyr Zelenskyy was quoted as saying that Siberia is now within Ukraine's reach. Refineries and energy infrastructure have become prominent targets in the war, carrying both economic and military weight. Independent confirmation of the strike's scale and of the damage to the refinery was still awaited, and each side's statements were being assessed separately.

The strike came just before a crucial NATO summit at which leaders are expected to address defence spending and support for Ukraine. Observers will watch how the developments shape the summit's discussions and energy markets in the days ahead.
