An Ukrainian drone attack sparked a fire at an oil depot in Sochi, the Russian resort that hosted the 2014 Winter Olympic which is 400 kilometres (250 miles) from the Ukrainian border, authorities said Sunday.
Ukraine has regularly hit Russian oil and gas infrastructure in response to attacks on its own territory since Russia began its offensive in February 2022.
"Sochi suffered a drone attack by the Kyiv regime last night," the governor of Russia's Krasnodar region, Veniamin Kondratiev, said on Telegram.
He said drone wreckage hit an "oil tank, which caused a fire" during the night-time attack.
Sochi's mayor, Andrei Proshunin, said there were no victims and that the fire was put out several hours later.
Images, broadcast by Russian media but whose authenticity AFP could not verify, showed flames and a thick plumes of black smoke rising from the site.
Air traffic was briefly suspended at Sochi airport, Russia's air transport regulator Rosaviatsia said.
Ukraine authorities have not commented on the fire.
Air strikes on Sochi are relatively rare compared to some other Russian cities.
However, Ukrainian drone attacks killed two people there late last month, according to local authorities.
Russian strikes
Kyiv has said it will intensify its air strikes against Russia in response to an increase in Russian attacks on its territory in recent weeks, which have killed dozens of civilians.
