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.

Editor's note: This story was updated with a statement made by Ukraine's General Staff.

Ukraine's military confirmed on July 7 that it targeted a chemical plant in Russia's Moscow Oblast used for producing ammunition and explosives, the General Staff said.

The plant, located 88 kilometers (55 miles) northeast of Moscow, produces industrial and military-grade chemicals, including explosives, ammunition components, and aircraft protection systems.

Established in 1915, the plant is one of the city's largest employers and plays a key role in Russia's defense-industrial complex. Its location in Krasnozavodsk places it roughly 530 kilometers (329 miles) from the Ukrainian border.

It is affiliated with the Russian state defense conglomerate Rostec and supplies the Defense Ministry, Interior Ministry, Federal Security Service (FSB), and other law enforcement agencies.

Moscow Oblast authorities have not officially confirmed the attack. Russia's Defense Ministry claimed that air defenses intercepted or destroyed 91 Ukrainian drones across multiple regions, including eight over Moscow Oblast.

In a statement released later on July 7, Ukraine's General Staff confirmed that units from its Unmanned Systems Forces, in coordination with other elements of the Defense Forces, carried out a precision strike against the Krasnozavodsk Chemical Plant.

The facility was specifically targeted to disrupt Russia's ability to produce explosive materials and ammunition, including thermobaric warheads used in Shahed-type drones.

"A series of explosions was recorded in the area of Krasnozavodsk, and firefighting equipment was seen moving through neighboring settlements," the statement read. The results of the strike are still being assessed, it added.

The Kyiv Independent could not independently verify the reports.

The reported strike comes as part of Ukraine's broader campaign to disrupt Russian logistics, weapons production, and supply lines far behind the front line.

In recent months, Ukrainian drones have hit multiple industrial and military sites across Russia, including oil depots, airfields, and electronics facilities.

Ukraine struck a critical Russian military-industrial site overnight on July 5 that produces components for high-precision weapons used by Moscow to attack Ukraine, the General Staff of Ukraine's Armed Forces reported.

The site in question is JSC VNIIR-Progress, a Russian state institute that specializes in developing electronic warfare (EW) systems, including the Kometa antenna arrays, used to jam satellite, radio, and radar signals.

The institute is located in Cheboksary, Chuvash Republic, about 1,200 kilometers (745 miles) away from the Ukrainian border.

The Kometa antenna is used in Shahed-type drones, Iskander-K cruise missiles, and guided aerial bomb modules — all high-precision weapons used by Russia to strike civilian and military targets across Ukraine.

The General Staff confirmed that Ukrainian weapons reached the target area but said final damage assessments were still underway.

The VNIIR-Progress institute has been sanctioned by both the United States and the European Union for its role in supporting Russia's war effort.

The Iskander-K is a precision-guided cruise missile with a range of up to 500 kilometers (311 miles), frequently used by Russia to target civilian areas. Shahed drones have become a central part of Moscow's airstrike tactics since late 2022 due to their low cost and high payload.

Located on the Volga River, Cheboksary is the capital of the Chuvash Republic and lies deep inside Russian territory. Russian independent media outlet Astra and local Telegram channels earlier reported explosions in the city overnight.

Russia's Defense Ministry claimed to have shot down two drones over the region.

This marks the second known Ukrainian drone strike on VNIIR-Progress. On June 9, explosions and fires were also reported at the facility following another drone attack.

The Kupol plant in Russia's Udmurt Republic ceased operations following a Ukrainian drone attack, independent media outlet Astra reported on June 2, citing emergency service sources.

Located more than 1,300 kilometers (800 miles) from the front line, the plant produces Tor and Osa air defense systems, as well as Harpy-type attack drones. It is under international sanctions as part of Russia's defense-industrial complex.

Two drones hit their intended targets during the strike with one flying through the windows of one workshop, and the second hitting the roof of another, causing an explosion and fire. The resulting blaze led to the collapse of 1,300 square meters of roofing, Astra reported.

Four workshops were destroyed in the first building of the complex, reportedly halting operations in areas responsible for metalworking, microchip soldering, and drone production.

Udmurt Republic Governor Alexander Brechalov said on June 1 that three people were killed and 45 injured in the attack, including 35 hospitalizations and six in serious condition.

Astra earlier reported that no air raid siren was issued in Izhevsk ahead of the attack. Residents claimed to be unable to receive emergency alerts due to persistent mobile internet outages.

Ukraine's General Staff confirmed the strike via its official Telegram channel, framing it as part of Kyiv's campaign to degrade Russia's defense-industrial base far from the front.

The plant was previously targeted in a Ukrainian drone strike on Nov. 17, 2024. That attack damaged equipment used to produce Tor missile systems and radar components.

Izhevsk, the capital of the Udmurt Republic, is known as a center of Russia's arms manufacturing industry and the birthplace of the Kalashnikov rifle.

The latest attack underscores Ukraine's capacity to strike deep into Russian territory.

Ukrainian drones struck the Saratovorgsintez oil refinery in Russia's Saratov Oblast, causing damage to the facility, Ukraine's General Staff reported on July 1.

"An important facility has been hit," the General Staff said via its official Telegram channel.

The Saratovorgsintez refinery and chemical plant, owned by Russian energy giant Lukoil, is located nearly 1,500 kilometers (930 miles) from Ukraine's border in the city of Saratov. The city hosts multiple strategic military and industrial sites.

The refinery was targeted to "reduce the enemy's offensive capabilities," the General Staff wrote.

"The occupiers use the capacity of this refinery to supply fuel and lubricants to Russian military units involved in the armed aggression against Ukraine."

The attack was a joint operation carried out by Ukraine's military intelligence agency (HUR) and other military units, the General Staff said. A fire broke out at the site of the attack and damage to the refinery's technological installations has been confirmed. The full consequences of the strike are still being investigated.

The Kyiv Independent could not verify these claims.

The report is the latest in a series of announcements on July 1 about successful Ukrainian strikes on Russian targets. Earlier in the day, HUR released footage of Ukraine's UJ-26 drones, commonly known as Bober (Beavers), targeting high-value Russian air defenses and a fighter jet in occupied Crimea.

A source in the Security Service of Ukraine (SBU) told the Kyiv Independent that Ukrainian drones struck a major Russian military plant in the city of Izhevsk, over 1,300 kilometers (800 miles) from the front lines.

Ukraine also hit a Russian command post in occupied Donetsk Oblast, according to the General Staff.

Ukraine's Armed Forces struck the Atlas oil depot in Russia's Rostov Oblast overnight on June 23, the General Staff reported.

The attack ignited a fire at the site, with Ukrainian forces saying the strike had reached its intended target. The facility supplies fuel and lubricants to Russian military units.

Yuri Slyusar, the acting governor of Rostov Oblast, confirmed that a fire occurred at an industrial facility after the attack. He added that no one was injured.

The full extent of the damage is still being assessed, according to the military.

Located near the Azov Sea and bordering Ukraine, Rostov Oblast plays a crucial logistical role for Russia's war effort due to its proximity to front-line operations. The same depot was previously targeted in November 2024.

"The defense forces continue to take all measures to undermine the military and economic potential of the Russian occupiers and force the Russian Federation to stop its armed aggression against Ukraine," the General Staff said.

The strike is part of Ukraine's broader campaign aimed at disrupting Russian supply chains and degrading its capacity to sustain the full-scale invasion.

Fuel depots, rail infrastructure, and ammunition stockpiles inside Russia and occupied territories have increasingly become targets for long-range drone and missile strikes.

The Nevinnomyssk Azot chemical plant — one of Russia’s largest producers of nitrogen fertilizer and ammonia and a key supplier to the Kremlin's military-industrial complex — has suspended production, Russian independent media outlet Astra reported on June 16.

According to Astra, the chemical plant suspended production as a direct result of Ukrainian drone strikes. The strike — which was confirmed by Ukraine’s General Staff on June 14 — targeted two major military-industrial facilities in Russia, including the Nevinnomyssk Azot plant in Stavropol Krai. The facility reportedly supplied raw materials and components for Russia’s weapons and fuel production.

Nevinnomyssk Azot is among Russia's top producers of ammonia and nitrogen fertilizers and hosts the country’s only production lines for methyl acetate and high-purity acetic acid. It also operates Russia’s first melamine production facility, according to open-source data.

According to Andrii Kovalenko, head of Ukraine's Center for Countering Disinformation at the National Security and Defense Council, the plant produces up to one million tons of ammonia and over one million tons of ammonium nitrate annually, is "a critical element of Russia's military-industrial complex."

Kovalenko noted that ammonium nitrate is a key component for explosives and artillery shells. He added that the plant also synthesizes dual-use chemicals such as melamine, acetic acid, methanol, and potassium nitrate — all frequently used in the production of grenade launchers, mines, and rocket charges.

Since 2024, the plant has also been producing water-soluble fertilizers, which he said have been adapted to serve military chemical needs as part of Russia's war in Ukraine.

The chemical plant is part of the EuroChem Group, owned by Russian billionaire Andrey Melnichenko, who is currently sanctioned by Canada, the European Union, Japan, and the United Kingdom.
