Russian-held Crimea, a popular tourism destination, suspended children’s summer camps and tourist activities until September 1, its governor said on Monday, as the peninsula reels from a fuel crisis due to Ukrainian attacks on its supply routes.

Supplies ‌of fuel and other products to Crimea have become strained as Ukraine has targeted both sea routes and supply roads from the north.

The availability of petrol and diesel in Russia, the world’s third-largest oil producer, has also been undermined by Ukrainian drone attacks on Russian oil refineries, including in Moscow.

Fuel stations in Crimea halted all fuel sales to individuals and businesses from Sunday, including cash, non-cash ⁠and voucher purchases.

Governor Sergei Aksyonov said on Monday that the closing of children’s camps was in the interests ‌of public security.
