May 9 (Reuters) - A Ukrainian drone attack sparked a

fire and damaged several storage tanks at a fuel depot in

Russia's Krasnodar region, the region's crisis administration

said on Thursday.

About six drones were destroyed and debris fell on the

refinery near the village of Yurovka, the administration said on

the Telegram messaging app.

"Several tanks were damaged," the administration said,

adding no one was injured in the attack.

Drone attacks on energy facilities inside Russia's territory

have become more frequent in the past few months. Kyiv officials

say that they conduct the attacks to undermine Russia's war

effort and respond to Moscow's strikes on Ukrainian energy

infrastructure.

The oil depot was last attacked on May 2, according to

Russian state media.
