Russia said on Sunday that Ukraine had launched a large-scale drone attack overnight, with more than 600 drones targeting Moscow.
Moscow Mayor Sergei Sobyanin said 201 of the drones had been destroyed by air defences in the Moscow region, while most had been intercepted before reaching the region.
He said three people had been injured in the attacks but did not provide information on possible damage.
The Kyiv Independent daily reported that Ukrainian forces had targeted a warehouse belonging to Russian online retail giant Wildberries and industrial sites, in cities across the region.
Russia launches ballistic missile attack on Kiev
Ukrainian authorities reported earlier that Russia had launched a new overnight ballistic missile attack on Kiev.
Mayor Vitali Klitschko said explosions had been heard in the Ukrainian capital and urged residents to remain in shelters while emergency crews were deployed.
Fires had been reported at multiple sites, Klitschko wrote on Telegram.
The Ukrainian Air Force said missiles, glide bombs and drone attacks had been recorded in other parts of the country, including the cities of Kremenchuk and Kryvyi Rih.
The statements from both sides could not be independently verified.
Ukraine has been fighting Russia's full-scale invasion for more than four years. Kiev has repeatedly warned of dwindling stocks of interceptor missiles for its Patriot air defence systems, which are used to defend against ballistic missile attacks.
