Long-range Ukrainian drones struck the Ilsky oil refinery in Russia's Krasnodar Krai on July 7, hitting one of the facility's technological workshops, a source in Ukraine's military intelligence (HUR) told the Kyiv Independent.

Located roughly 500 kilometers (311 miles) from Ukrainian-controlled territory, the refinery is among the largest in southern Russia, producing over 6 million tons of fuel annually.

It is involved in the reception, storage, and processing of hydrocarbons and distributes refined products via road and rail. The refinery is part of Russia's military-industrial complex and plays a direct role in supporting Moscow's war effort, the source said.

The Russian regional operational headquarters claimed that "drone debris" fell on the oil refinery.

The strike marks a renewed wave of Ukrainian attacks on Russian oil infrastructure, following a months-long pause since March. On July 1, Ukrainian drones struck the Saratovorgsintez oil refinery in Russia's Saratov Oblast.

Kyiv has targeted dozens of refineries, oil depots, and military-industrial sites since the start of Russia's full-scale invasion in 2022. Winter drone attacks forced at least four Russian refineries to temporarily shut down.

This is the second known strike on the Ilsky refinery. Ukrainian drones, operated by the Security Service (SBU) and Special Operations Forces (SSO), previously targeted the facility on Feb. 17, causing a fire.

Krasnodar Krai, a strategic region along Russia's Black Sea coast, has increasingly come under Ukrainian drone attacks as Kyiv extends the range of its strikes deep into Russian territory.

HUR first made the claim on July 5, saying Russia was increasing its forces at the Gyumri base to exert greater influence in the South Caucasus and “destabilize the global security situation.”

Drones attacked Russia's Black Sea Fleet at the port of Novorossiysk in Krasnodar Krai overnight on July 6, the Russian media outlet Astra reported.

Ukraine has not officially commented on the reported strikes, and the Kyiv Independent could not independently verify the claims.

An air alert was sounded in the city for several hours, and air defense was active. The consequences of the attack are still being determined, according to Astra.

The media outlet also published footage purportedly showing a burning maritime drone that was allegedly shot down during the attack.

Krasnodar Krai is located east of Crimea, with the Kerch Strait separating them at their closest point.

Ukraine regularly strikes military targets within Russia as Moscow continues to wage its war against Ukraine.

The Russian Defense Ministry claimed that Russian forces downed 120 drones overnight on July 6.

Thirty drones were shot down over Bryansk Oblast, 29 over Kursk Oblast, and 18 over Oryol Oblast, according to the ministry. An additional 17 and 13 drones were reportedly intercepted over Belgorod and Tula oblasts, respectively, the ministry said.

Due to drone attacks in Russia, numerous flights were canceled or delayed at several airports, including Moscow's Sheremetyevo Airport, overnight between July 5 and July 6.
