Drones that the Kremlin said were launched by Ukraine flew deep inside Russian territory, including one that got within 100 kilometers (60 miles) of Moscow, signaling breaches in Russian defenses as President Vladimir Putin ordered stepped-up protection at the border.
Officials said the drones caused no injuries and did not inflict any significant damage, but the attacks on Monday night and Tuesday morning raised questions about Russian defense capabilities more than a year after the country’s full-scale invasion of its neighbor.
Ukrainian officials did not immediately take responsibility, but they similarly have avoided directly acknowledging responsibility for past strikes and sabotage while emphasizing Ukraine’s right to hit any target in Russia.
Although Putin did not refer to any specific attacks in a speech in the Russian capital, his comments came hours after the drones targeted several areas in southern and western Russia. Authorities closed the airspace over St. Petersburg in response to what some reports said was a drone.
