Drone attacks deep inside Russian territory have increased since a drone was destroyed over the Kremlin in early May.

The attack on Moscow on Thursday is the latest in a series of Ukrainian drone raids deep inside Russian territory.

The defence ministry said in a statement that two drones “flying in the direction of the city of Moscow were destroyed”, while 11 others were brought down near the city of Sevastopol.

Two of the Ukrainian drones were “hit by on-duty anti-aircraft defence equipment, another nine were suppressed by means of electronic warfare and crashed in the Black Sea before reaching the target”, the ministry said of the attack.

There was no immediate comment from Ukraine.

Thursday’s reported drone raid comes a day after Russia said it had shot down two Ukrainian combat drones that were deployed to attack Moscow, one near a major airport to the south of the Russian capital and one to the west of the city.

Ukrainian air attacks inside Russia have increased since the first reported drone attack against the Kremlin was averted in early May.

Civilian areas of the city were the focus of drone attacks later in May and a Moscow business district was targeted twice in three days earlier this month.

The New York Times reported in May that United States intelligence agencies believe Ukrainian spies or military intelligence were behind the initial drone strike on the Kremlin.

Russia has also launched thousands of long-range drone strikes on Ukraine throughout the war, often striking civilian targets far from the front lines.

Russian drones destroyed a fuel depot in Ukraine’s western Rivne region on Thursday, regional governor Vitaliy Koval wrote on the Telegram messaging app.

There were no casualties from the attack, he said.
