At least 10 Ukrainian drones were shot down on their approach to Moscow overnight into Sunday morning, according to the city's mayor.

Ukraine’s drone strike deep inside Russian territory left Kremlin officials angry and alarmed over the sudden vulnerability of a nuclear-capable air fleet far from the battlefield, according to people close to senior officials in Moscow.

Russian air defense successfully neutralized three drones targeting Moscow, according to the city's mayor. Emergency services handled debris fallout, while operations at nearby airports were briefly halted for safety reasons.
