Ukraine launched its biggest ever drone attack on Moscow on Tuesday but air defences destroyed all eight of the drones, Russia said, bringing the 15-month war in Ukraine to the heart of the capital.

Drone attacks deep inside Russia have intensified in recent weeks ahead of an expected Ukrainian counter-offensive, with strikes on oil pipelines and even the Kremlin earlier this month that Moscow has blamed on Ukraine.

The drone attacks hit some of Moscow’s most prestigious areas including Leninsky Prospekt, a grand avenue crafted under Josef Stalin, and the area of western Moscow where the Russian elite - including President Vladimir Putin - have their residences.

Residents in south-western Moscow said they heard loud bangs at around 0200 to 0300 GMT, followed by the smell of petrol. Some filmed a drone being shot down and a plume of smoke rising over the Moscow skyline.

“This morning, the Kyiv regime launched a terrorist attack with unmanned aerial vehicles on premises in the city of Moscow,” Russia’s defence ministry said.

“Eight unmanned aerial vehicles were involved in the attack. All enemy drones were hit.”

Moscow Mayor Sergei Sobyanin said two people were injured, one of whom was hospitalised, in the early morning attack. Moscow’s airports remained open. No deaths were reported.

The defence ministry said special electronic counter-drone technology was used to divert three of the Ukrainian drones while five more were shot down, including by Pantsir missile systems which help defend Moscow.

A Ukrainian presidential aide denied Kyiv was directly involved in the Moscow attack, but said Ukraine was enjoying watching events and forecast more to come.

“Of course we are pleased to watch and predict an increase in the number of attacks. But of course, we have nothing directly to do with this,” Ukrainian presidential adviser Mykhailo Podolyak said.

Kyiv denied that it was behind the drone raid on the Kremlin earlier this month, though The New York Times reported that US intelligence believes Ukraine was responsible.

There is little sign of peace in one of the deadliest wars in Europe since World War Two, and Moscow has repeatedly warned that the West is escalating the war by supplying Kyiv with so much weaponry.

MOSCOW UNDER ATTACK

It was unclear how Putin will react to the drone attack, which brings the war in Ukraine to the capital of the world’s biggest nuclear power.

So far Putin has kept the war in Ukraine far from Moscow, where life has continued relatively normally despite the biggest crisis in Russia's ties with the West since the 1962 Cuban Missile Crisis.

Russia began attacking the Ukrainian capital with swarms of cheaply produced loitering munitions often known as “kamikaze drones” last October and uses them extensively during its regular air strikes across Ukraine.

Prosecutors said incidents occurred in the Odintsovsky District of western Moscow region - where Putin has his Novo-Ogaryovo state residence. The area, the most expensive in Russia, is the home to Russia’s elite.

Russian state television gave the attacks some coverage but it was not extensive.

Putin has repeatedly cast the conflict in Ukraine as a struggle with what he says is an arrogant and aggressive West which is risking a global war by supporting Ukraine.

Thus far, the war has been described by the Kremlin as a “special military operation”. The United States has repeatedly said it does not want a war with Russia and has said Ukraine should not use Western weapons to attack inside Russia.

Russian lawmaker Alexander Khinshtein, from the ruling United Russia bloc, said the attacks on Moscow were likely to increase.

“The sabotage and terrorist attacks of Ukraine will only increase,” Khinshtein said. “It is necessary to radically strengthen defence and security measures, especially in terms of countering drones. This includes finally passing the necessary laws.”
