KYIV, Aug 2 (Reuters) - Ukraine's military said on

Saturday that it had struck oil facilities inside Russia,

including a major refinery as well as a military airfield for

drones and an electronics factory.

In a statement on Telegram, Ukraine's Unmanned Systems

Forces said they had hit the oil refinery in Ryazan, about 180

km (110 miles) southeast of Moscow, causing a fire on its

premises.

Also hit, the USF said, was the Annanefteprodukt oil storage

facility in the Voronezh region that borders on northeastern

Ukraine.

The statement did not specify how the facilities were hit,

but the USF specialises in drone warfare, including long-range

strikes.

There was no immediate comment from Russia on the reported

attacks on its infrastructure sites.

Separately, Ukraine's SBU intelligence agency said its

drones had hit Russia's Primorsko-Akhtarsk military airfield,

which has been used to launch waves of long-range drones at

targets in Ukraine.

The SBU said it also hit a factory in Penza that it said

supplies Russia's military-industrial complex with electronics.

At the start of Russia's full-scale invasion in 2022,

Ukraine had no response to Moscow's vast long-range strike

capacity but it has since built up a fleet of long-range

kamikaze drones able to carry explosive warheads for many

hundreds of kilometres (miles).

Russia's defence ministry said in its daily report that its

defence units had downed a total of 338 Ukrainian drones

overnight. Its reports do not say how many Ukrainian drones were

launched at any given time.

For its part, Ukraine's air force said it had downed 45 of

53 Russian drones launched towards its territory overnight.

On Ukraine's eastern battlefront, Russia's defence ministry

said, Russian forces had captured the village of

Oleksandro-Kalynove in the Donetsk region on Saturday.

Reuters could not immediately verify the battlefield report.

Russian forces now control almost 20% of Ukraine in its east

and south after three-and-a-half years of grinding war.
