Il Nuovo Postiglione - Kyiv claims new attack on oil depot in Russia

The strike is the second on a Russian oil depot in as many days, part of what Kyiv has called "fair" retaliation for Moscow's strikes on Ukrainian energy infrastructure.

Friday's strike targeted a Rosneft oil storage facility about 50 kilometres (30 miles) from the Ukrainian border, in the Russian town of Klintsy, officials said.

It was carried out by the Main Intelligence Directorate of the Ukrainian Ministry of Defence, a Ukrainian security source confirmed to AFP, without elaborating.

Videos showed a huge fireball tearing through the oil depot's storage tanks, while a cloud of black smoke billowed over the town of some 60,000 inhabitants.

"Four oil tanks are burning in Klintsy," regional governor Alexander Bogomaz said.

"For safety reasons 32 residents of the private sector were temporarily evacuated to relatives. A temporary accommodation centre has been prepared," he added.

There were no casualties, but 13 fire trucks were deployed to battle the blaze, Bogomaz announced earlier.

The fire started after a drone dropped "munitions" on the depot, he said, but claimed the drone had been intercepted.

Two other drones targeting the region were shot down by air defences, he said.

A train especially equipped to deal with large fires was scrambled to the town to help battle the blaze, a local train operator said.

"The fire will not affect rail traffic in Klintsy," it stressed.

Kyiv has targeted Russian territory including its oil and gas infrastructure throughout the almost two-year war, but these strikes have intensified in the past two months.

On Thursday, Ukraine claimed responsibility for a rare drone attack in the northern Leningrad region, nearly 1,000 kilometres (around 620 miles) from the border.
