Feb 5 (Reuters) - A Ukrainian drone attack overnight

sparked a fire at an oil depot in Russia's southern region of

Krasnodar, its governor said early on Wednesday, with 55 people

fighting the blaze.

A series of drone attacks by Ukraine on Russia's energy

facilities have sparked fires in recent days at a major oil

refinery in the Volgograd region, as well as at the Astrakhan

gas processing plant.

"The fire has been contained, there are no casualties,"

Veniamin Kondratyev, governor of the Krasnodar region, said on

the Telegram messaging app, with a team wielding 19 items of

equipment to try and extinguish the flames.

Kondratyev did not say which depot was on fire or detail the

extent of damage.

The Russian defence ministry said that four Ukrainian drones

were destroyed over the Russian territory overnight, but did not

mention the Krasnodar region in a statement on the Telegram

messaging app.

The ministry only reports drones that its air defence

systems destroy, not how many were launched.

There was no immediate comment from Ukraine. Kyiv says that

its attacks inside Russia are aimed at destroying infrastructure

key to Moscow's war in Ukraine and are in response to Russian

continued bombing of Ukraine.
