At least four people were killed and 28 wounded in overnight Ukrainian drone attacks targeting oil facilities in Crimea and Russia's Krasnodar region. The strikes, which occurred into Sunday, hit an oil depot and fuel facilities crucial for supplying Russian forces.

Crimea, annexed by Russia in 2014, has become a key target for Ukraine as it seeks to disrupt Russian supply lines and military operations. The peninsula hosts Russia's Black Sea Fleet headquarters, and recent Ukrainian drone activity has intensified, exacerbating a fuel crisis as the summer tourist season begins.

Sergey Aksyonov, Crimea's Moscow-installed leader, confirmed the casualties in the attacks. Social media channels reported multiple explosions and fires across Crimea, with one Telegram channel indicating a large fire at the fuel depot in Kerch, a port city at the peninsula's eastern end. Russian authorities temporarily closed the Kerch Bridge, which connects Crimea to Krasnodar, due to the incidents.

In Russia's Krasnodar region, east of Crimea, a separate Ukrainian drone attack struck an oil transport facility. Local authorities reported that one person was killed on a passenger ferry and an oil terminal caught fire. The Russian Ministry of Defence stated that it had shot down 239 Ukrainian drones overnight.

President Volodymyr Zelenskyy acknowledged Ukraine's role in striking the oil depot in Kerch and the transport facility in Krasnodar. These attacks come amid a broader Ukrainian strategy to degrade Russia's logistical capabilities and exert pressure on its occupied territories.

The damage to infrastructure has led to reported outages in electricity networks in Crimea, and fuel deliveries have been delayed. Sevastopol Governor Mikhail Razvozhayev indicated that fuel was being prioritized for official services, with a planned allocation for private motorists canceled.

Crimea's tourism industry, a significant draw for Russian travelers, is bracing for a potential downturn, with predictions that millions of tourists may avoid the peninsula this summer due to the ongoing conflict and associated disruptions.

Russia occupied and annexed Crimea in March 2014 following a referendum that was not internationally recognized. Since its full-scale invasion of Ukraine in February 2022, Russia has utilized the peninsula as a staging ground for military operations against the Ukrainian mainland.
