Authorities in Russian-annexed Crimea completely halted the sale of motor fuel to private individuals and commercial businesses on June 21 amid a worsening shortage.
Sergei Aksyonov, the Russian-installed head of Crimea, said that starting at 9 a.m., fuel at filling stations would be sold only to government bodies responsible for essential services and security.
Strict restrictions on gasoline sales were already in place on the peninsula. In Sevastopol, QR codes had been used since June 6 to allow motorists to purchase up to 20 liters of fuel per week.
The new stage of the crisis came amid a series of Ukrainian strikes on oil and transport infrastructure in Crimea and southern Russia. Russian authorities also temporarily suspended ferry traffic across the Kerch Strait overnight on June 21.
Aksyonov said four people were killed and 28 wounded in a Ukrainian attack on Crimea. Those casualty figures were provided by the Russian-installed authorities on the peninsula.
Ukraine has intensified attacks in recent weeks on Russian energy infrastructure and supply routes serving annexed Crimea.
