Ukraine launched a large-scale drone attack on Moscow on June 18, 2026, targeting a major oil refinery run by a subsidiary of state-owned Gazprom. According to France24, nearly 200 drones were fired at the city during the operation. The strikes caused fires at the refinery and surrounding areas, resulting in black rain and smoke falling over Moscow. At least 17 people were wounded in the attacks, which forced the evacuation of passengers and disrupted flights at Moscow's largest airports.

This incident marks the second strike on the Moscow oil refinery in a week and is described as the largest or one of the largest drone attacks on the city since the start of the full-scale invasion. The attack demonstrated Ukraine's ability to penetrate Russian air defenses and strike key infrastructure. The assault occurred while Russian President Vladimir Putin was hosting Southeast Asian leaders at a summit in Kazan.

Reporting on the political context, Times of Israel reported that Ukrainian President Volodymyr Zelensky described the attack as a justified response to attacks on Kyiv. Meanwhile, Dawn reported that Russia vowed to retaliate for the strike. Ukraine is targeting Russian territory to impact Russia's war capabilities.
