Drivers in Russian-controlled Crimea were grappling ⁠with gasoline rationing on ​Monday after Ukrainian drone attacks constricted road supplies ⁠across south-eastern Ukraine, Reuters witnesses and officials said.

More than four years since ​the 2022 invasion of Ukraine, Russia is facing almost daily Ukrainian attacks on its oil infrastructure while Western sanctions have made crude exports more costly.

Moscow-backed Crimea governor, Sergei Aksyonov, said limits had been imposed on sales of the most commonly used gasoline, Ai-95, and that people would have ⁠to use fuel coupons for purchases.

In Sevastopol, the largest city in Crimea and the traditional base of Russia’s ​Black Sea Fleet, Reuters witnesses reported long queues at filling stations.

“I haven’t been able to fill up for two days now,” resident Oksana Senchenko told Reuters.
