Ukraine carried out a series of long-range strikes on Russian military targets early Thursday, Feb. 12, hitting an ammunition depot near Volgograd and a missile manufacturing facility in Russia’s Tambov region, according to Ukrainian officials.

Ukraine’s General Staff confirmed that Ukrainian forces struck a major Russian arsenal near the village of Kotluban in the Volgograd region in the early hours of Thursday morning. The facility stores missiles, ammunition and explosives belonging to the Main Missile and Artillery Directorate of Russia’s Defense Ministry.

“This arsenal is one of the largest ammunition storage sites of the Russian army. It was struck by Ukrainian long-range FP-5 ‘Flamingo’ weapons,” the General Staff said in its statement.

The report said powerful explosions were recorded at the site, followed by secondary detonations. The extent of the damage is still being assessed.

In a separate strike, Ukrainian forces hit the Michurinsk Plant Progress in the Tambov region, an enterprise that produces high-tech equipment for aviation and missile systems and supplies the Russian military. Preliminary information indicates a fire broke out on the plant’s grounds. Damage assessments are ongoing.

Ukrainian forces also struck Russian ammunition depots near the occupied settlement of Terpinnya and near Rozivka in Ukraine’s Zaporizhia region, the General Staff said.

The reported strike would mark one of the longest-range attacks inside Russian territory since the start of the war.

Volgograd Region Governor Andrei Bocharov said the region came under missile fire, triggering a blaze at a Russian Defense Ministry facility near the village of Kotluban.

He said no residents were injured and no civilian property was damaged.

However, due to the “threat of detonation during firefighting,” authorities evacuated Kotluban residents to temporary accommodation centers in Gorodishche, the governor added.

The Russian Telegram channel Astra reported that military unit 57229/51 was hit. Publicly available data indicate that the arsenal of the Main Missile and Artillery Directorate of the Russian Defense Ministry is located on the site.

The same facility was previously targeted several times. Astra reported drone strikes there in November 2023 – one of which set a small-arms ammunition depot ablaze, forcing the evacuation of 630 people – as well as attacks in March 2024 and March 2025.

The city of Michurinsk in Russia’s Tambov region was also struck by drones, regional governor Yevgeny Pervyshov said.

According to him, the attack caused a fire at a Magnit supermarket and damaged several buildings, including the Industrial and Technological College. Two people were injured.

Astra reported that the likely target was the Michurinsk Progress Plant, located near both the burned supermarket and the college – about 150 meters from the college and roughly 100 meters from the store.

One eyewitness video reviewed by the Astra outlet shows a strike on the plant, though it remains unclear whether the facility itself sustained damage.

Progress is a major industrial enterprise specializing in high-tech mechanical engineering and produces equipment for aircraft and missile control systems.

Following the overnight attack, all schools in Michurinsk canceled classes, the mayor said.

Astra’s OSINT analysis also linked the strike to a fire near the Michurinsk railway station. The outlet verified an eyewitness photo showing smoke near Michurinsk-Uralsky station, the city’s main rail hub, though the exact source of the fire could not be confirmed.

Russia’s Defense Ministry claimed its air defenses “intercepted and destroyed” 106 Ukrainian fixed-wing drones overnight, including one over the Volgograd region and 13 over Tambov.

The ministry did not mention any missile strike on Volgograd in its statement.

Notably, Lukoil’s Volgograd oil refinery was damaged in an overnight drone attack on Wednesday, Feb. 11. Bocharov confirmed a fire at a refinery in the city’s southern district, saying there were no casualties.

“Emergency services and municipal authorities are searching for and removing possible UAV debris,” he added.

The Telegram channel Astra, citing OSINT analysis of eyewitness footage, reported that the Lukoil-Volgograd refinery in the Krasnoarmeysky District was struck and caught fire.

The facility is the largest oil refinery in the Volgograd Region and one of Lukoil’s key assets, processing more than 15 million tons of oil annually. It produces gasoline, diesel and aviation fuel, fuel oil, bitumen, and other petroleum products.

Astra estimates this was at least the ninth attack on the refinery since the start of Russia’s full-scale invasion.

Later, Ukraine’s General Staff confirmed that the Volgograd refinery, which supplies the Russian military, had been hit.

“A fire was recorded at the site. The extent of the damage is being clarified,” the statement said.

In Thursday’s report, General Staff confirmed that the Feb. 11 strike on the Volgogradsky oil refinery damaged the main primary oil processing unit ELOU-AVT-1, elements of AVT-3, and other infrastructure facilities. At other units, including secondary processing facilities, operations were reduced or halted.
