Ukraine is destroying air defence systems near Russian president Vladimir Putin’s $1bn palace on the Black Sea coast, according to reports.

Two attacks over the last week have targeted military assets in Gelendzhik, around 12 miles from the Russian leader’s holiday home.

On 7 August, Ukrainian drone attacks struck Volna Kupol Garant, Russian electronic warfare equipment designed to jam Starlink communications over an area of 20 sq m, The Moscow Times reports.

On Sunday, a further strike was launched on an S-400 anti-aircraft missile system and launch pad just 500m away from the previous attack.

Major Robert Brovdi, commander of Ukraine’s unmanned systems forces said the S-400 had fired six missiles on Sunday night before it was left “ablaze and sputtering for three hours”.

Satellite imagery appeared to confirm the destruction of at least one launcher, military analyst Yan Matveyev told the Moscow Times.

“Now Putin’s palace is left unprotected,” he said. The S-400 is use to defend against air attacks from missiles and drones alike.

Ukraine has been launching attacks deeper into Russian territory in recent weeks, including a drone attack more than 600 miles into enemy territory earlier this week.

Putin’s residences enjoy extensive protection, including 27 air defence towers and anti-aircraft systems around his Lake Valdai mansion, according to an investigation by Radio Svoboda using satellite imagery.

In May, a leaked European intelligence report suggested the Russian leader was going to extreme lengths to ensure his safety including hiding out in a bunker for weeks at a time to avoid assassination.

Putin’s Black Sea mansion was first exposed following an investigation by his opponent Alexei Navalny’s Anti Corruption Foundation that estimated the construction of the building cost $1.2bn.

The huge complex is said to cover 7,000 hectares of land included a cinema, multiple restaurants and a hockey rink all surrounded by a no-fly zone, reportedly owned by the Russian’ security service (FSB).

Earlier this month, eyewitness footage appeared to show the moment a drone exploded at the Arkhipo-Osipovka beach resort near the Black Sea mansion.

At least seven people were killed including three children after the aircraft crashed on to a beach on 3 August. Around 40 other people were injured in what Russia claimed was a deliberate Ukrainian attack on civilians. Both sides deny targeting civilians.
