Shortly before dawn on Sunday, residents of the Moscow region were woken by air-raid sirens and the sound of interceptions overhead. Six hundred Ukrainian drones had been launched in a single overnight assault, according to Sergei Sobyanin, the city's mayor — a figure that, if confirmed, would represent the most ambitious long-range strike Ukraine has mounted since the war began in February 2022. Three people were wounded, Sobyanin said, and local authorities reported damage across several districts on the capital's outskirts. The assault did not occur in isolation.

While Ukrainian drones were being tracked over Russian territory, Russian forces launched their own missile attack on Kyiv, igniting fires in at least two of the Ukrainian capital's districts. Mayor Vitali Klitschko confirmed the strikes and urged residents to remain in shelters. The near-simultaneity of the two attacks underlines how the conflict has evolved from a largely ground-based war of attrition in eastern Ukraine into an exchange of long-range blows reaching deep into both countries' heartlands. Ukraine has been steadily expanding the range and scale of its drone programme since 2024, drawing on domestically produced systems that can travel over 1,000 kilometres.

Western officials have watched the escalation carefully, aware that strikes on Moscow carry symbolic and political weight that strikes on the front line do not. Russia, for its part, has continued to target Ukrainian cities with missile and drone barrages that have caused widespread civilian casualties throughout the war.
