Several drones have been intercepted near Moscow, says the mayor.

Several drones were intercepted early Tuesday in the Moscow region, also near an airport, Russian officials said, blaming Ukraine for the latest air raid on Russia’s political and economic heartland.

Moscow Mayor Sergei Sobyanin said the attacks targeted the suburbs of Moscow and the Moscow region and were all shot down by air defenses. There were no injuries or deaths, he added.

It appeared to be the first such strike since May, when two waves of drones came close to the Kremlin and hit civilian areas, bringing the conflict sparked by the war in Ukraine to Russia’s political and economic heart. Russia said Ukraine was behind the attacks, while Kiev denied involvement.

The Russian Ministry of Foreign Affairs convicted what it said was “the Kiev regime’s attempt to attack an area where civilian infrastructure is located, including an airport, which incidentally also serves international flights.”

Flights to Vnukovo airport, on the southwestern outskirts of the capital, were temporarily diverted Tuesday morning for security concerns, the mayor said. Earlier, Russian state media reported that some of the drones had been intercepted in the village of Valuevo in the suburb of New Moscow, near the airport, citing emergency services.

Ministry of Defense of Russia said five drones had been intercepted Tuesday morning. Four were shot down by air defense systems and one was intercepted by electronic jamming and then crashed in the Odintsovo district of Moscow’s outskirts, the ministry said. Falling debris from one of them caused a fire in a farm outbuilding, the state news agency Tass said.

Kremlin spokesman Dmitri S. Peskov said all attack drones targeting Moscow had been shot down, implying an effective response from the city’s air defense systems.

On May 3, two drones were flown towards the Kremlin, causing little damage. US officials said it was likely orchestrated by one of Ukraine’s special military or intelligence units. On May 30, at least eight drones targeted areas in and around the capital, the first attack to hit civilian areas.
