Some of the drones were shot down over the city of Podolsk, Moscow Mayor Sergei Sobyanin said. The city in the Moscow region is some 38 km (24 miles) south of the Kremlin.

“This is one of the largest attempts to attack Moscow using drones ever,” Sobyanin said on the Telegram messaging app in the early hours of Wednesday. “The layered defence of Moscow that was created made it possible to successfully repel all the attacks from the enemy UAVs.”
