An apocalyptic scene unfolded in Moscow after Ukraine executed its largest drone attack since the full-scale war began, leaving parts of the Russian capital blanketed by an eerie "black rain." The massive wave of long-range drones successfully penetrated Moscow’s dense air defenses, striking the critical Kapotnya oil refinery and triggering massive industrial explosions. The resulting toxic cloud rained oily soot onto vehicles, homes, and streets across southeastern districts, prompting emergency warnings for vulnerable residents to flee. Ukrainian President Volodymyr Zelenskyy confirmed the strike was direct retaliation for Russia's devastating bombardment of the historic Kyiv Pechersk Lavra monastery.
