Fuel stations on the Russian-held Crimean peninsula were out of petrol on Thursday, Reuters witnesses said, as a Ukrainian campaign against supply lines to the peninsula escalates.

A Reuters witness in Sevastopol, the peninsula's largest city, said that there was no ‌fuel at most local petrol stations, with supplies struggling even ​to keep up with a rationing regime imposed in recent weeks.

Another, in the resort town of Yevpatoriya, said ⁠that there was a long queue outside the single working petrol station there.

Ukraine ​has been intensifying drone strikes on supply lines to the peninsula, which ⁠Russia seized from Kyiv in 2014. Local authorities have imposed fuel rationing regimes, with some foodstuffs also running short.

On Wednesday, Russian-backed Sevastopol governor Mikhail Razvozhaev said that plans for ‌distributing rationed petrol had been delayed because trucks had been ​unable to bring ‌the fuel into the city, following recent Ukrainian strikes on supply routes.

Fuel is mostly delivered to Crimea ‌by road and rail via the Russian-held territories to the north, which Moscow overran in 2022. Those routes have increasingly been disrupted by ⁠drone attacks.

Fuel previously reached Crimea by ‌barge to an oil ⁠terminal in the city of Feodosia, but supplies were cut after Ukraine struck the terminal ⁠in ⁠April.

In Sevastopol, the Moscow-installed governor said that Ukrainian drones had caused light damage overnight, with 33 downed. The ‌Russian-backed governor of the Moscow-held part of Kherson region, which borders Crimea to the north, said that Ukraine had targeted bridges in the region, causing ‌some damage.

Kyiv ​also struck in ‌southern Russia overnight, authorities said, causing damage including a fire at the Afipsky oil refinery that has since been extinguished.

The governor of ​neighboring Adygea also reported damage to civilian infrastructure across the region.
