March 24 (Reuters) - Firefighters continued for the

fifth day to fight a fire at an oil depot in Russia's Krasnodar

region, sparked last week by a drone attack that authorities

blamed on Ukraine, the regional administration said.

"One of the tanks and oil products inside the facility are

burning," the administration said in a post on the Telegram

messaging app on Sunday local time.

As of 1700 GMT on Sunday, the area of the fire at the depot

near the village of Kavkazskaya was around 2,000 square metres

(21,500 square feet), the administration said on Telegram.

The fire area nearly doubled the night before following an

oil products spill.

The Russian foreign ministry said the attack amounted to a

violation of an agreement to halt attacks on energy

infrastructure under efforts to secure a ceasefire in the war in

Ukraine.

Local authorities had brought in firefighting trains loaded

with water to help to battle the blaze on Saturday.

The depot is a rail terminal for Russian oil supplies for a

pipeline to Kazakhstan.
