A Ukrainian drone attack on Bryansk airport overnight on 5–6 June destroyed a Russian Mi-8 helicopter and damaged a Mi-35, according to Russian news Telegram channel Astra. There are signs of the long-lasting military use of the civilian facility, Militarnyi notes.

Astra reported that the Ukrainian UAVs targeted the territory of the Bryansk International Airport last night located in the village of Oktyabrskoye near Bryansk. As a result of the strike, a Mi-8 helicopter was completely destroyed and its ammunition detonated. A Mi-35 military helicopter was also partially damaged.

According to Astra’s sources within the Russian Ministry of Emergency Situations, the strike also damaged the airport’s administrative building and the local rescue service facility. There were no casualties reported. Several dozen workers were evacuated from the nearby Ozon warehouse due to the explosions.

Video footage published by several Telegram channels showed secondary explosions after the initial impact. 

Additionally, last night, the Ukrainian drones struck an oil depot in Engels in Russia’s Saratov Oblast, and targeted Ryazan’s Dyagilevo airbase, and the Progress plant in Michurinsk, Tambov Oblast — a facility involved in producing components for rocket and aviation systems.

Militarnyi cited OSINT analysts from the Oko Hora group, noting that satellite imagery showed two objects — likely helicopters — regularly changing positions at the airfield, indicating long-term deployment and military use of the civil airport.

Militarnyi added that what exactly Russia stored in these airport buildings remains unclear, but the power of the explosions and the detonation observed by eyewitnesses suggest that an ammunition depot may have been present, possibly leading to the destruction and damage to Russian aircraft.

A fire and explosion occurred at the Zavolzhsky Motor Plant in Russia’s Zavolzhye, Nizhny Novgorod Oblast, reportedly injuring one worker, according to Astra and official statements from regional labor authorities.

Truck fire erupts in chemical workshop

The Russian news Telegram channel Astra reported on 3 June that the incident took place at night when a long-haul truck caught fire inside a workshop containing chemical substances.

The local Gostrudinspektsiya – a labor conditions inspection body – confirmed the event and said one worker sustained burns covering 10% of the body, and added that all circumstances and potential causes of the workplace incident are being investigated.

Authorities noted the blaze began on 2 June and are awaiting notifications from both the employer and the medical institution treating the injured worker. 

Plant linked to military engine production

The Zavolzhsky Motor Plant produces gasoline and diesel engines and is located in the city of Zavolzhia. Media reports emphasized that the factory manufactures engines used in military equipment. Astra reiterated that point, stating:

“The plant also produces engines for military vehicles.”

Russian publication Kommersant previously reported in 2003 that the plant had received a state contract to develop a line of competitive multipurpose diesel engines ranging from 2.2 to 3.4 liters in displacement. At the time, the plant’s director claimed the new engines would be reconstructed versions of the ZMZ-514 and suitable for a range of vehicles, including off-road models, class-D vehicles, 4-ton trucks, and military hardware.

A Russian military train was blown up near the occupied town of Yakymivka in Zaporizhzhia Oblast overnight on 31 May, damaging fuel wagons and a vital supply route used by Moscow’s forces to support occupied Crimea, Ukraine’s defense intelligence agency reported.

According to Ukraine’s Main Intelligence Directorate (HUR) of Ukraine’s Ministry of Defense, the explosion occurred on the railway line close to Yakymivka in the Melitopol district. The freight train, which included fuel tanks, was moving toward occupied Crimea when the blast hit. As a result, freight cars and tanker cars went off the rails, and the track was severely damaged.

HUR described the targeted section as “a key logistical artery of the Russians on the occupied territories of Zaporizhzhia Oblast and Crimea.” The agency stated that this disruption undermines Moscow’s ability to maintain military logistics in the south.

In response to the attack, Russian occupation forces declared a standard police “interception plan” across the occupied part of Zaporizhzhia Oblast, HUR reported. Authorities increased the number of military patrols in local settlements and intensified checks at checkpoints.

Recent attacks and incidents on Russian trains and infrastructure

On 25 May, Ukrainian military intelligence reported a drone strike on another Russian freight train transporting fuel in the occupied part of Zaporizhzhia Oblast.

That same evening, a train in Russia’s Belgorod Oblast was damaged after hitting an explosive device, according to regional governor Vyacheslav Gladkov.

In the early hours of 1 June, two bridge collapses occurred in Bryansk and Kursk oblasts. In Bryansk, a car bridge collapsed onto a passenger train, killing at least seven people. In Kursk, an accident on a railway bridge involving a freight train was reported, with no initial casualties mentioned.

Two explosions in the early hours of 30 May near Desantnaya Bay in Russia’s Vladivostok were part of a planned operation by Ukraine’s military intelligence agency (HUR), according to Ukrainian outlets RBC-Ukraine and UNIAN.

Sources say the blasts targeted the 47th Separate Air Assault Battalion of Russia’s 155th Guards Naval Infantry Brigade (Unit No. 30926). One explosion reportedly struck a checkpoint, the other hit an area housing personnel and commanders.

This brigade has been actively involved in combat against Ukraine, including documented deployments in Mariupol, Vuhledar, and Kursk Oblast.

Injuries and equipment losses reported by media

According to the same sources, the attack caused injuries and material damage.

“Personnel, military equipment, and special assets were hit,” the reports quoted unnamed intelligence sources as saying.

Citing local residents, RBC reported that at least ten ambulances and an evacuation helicopter arrived at the scene. Damaged military hardware was reportedly removed from the site using Russian military URAL trucks.

Russian officials: Gas leak caused the blasts

Russian authorities confirmed two explosions but denied any casualties or damage. The Anti-Terrorism Commission of Primorsky Krai attributed the incident to the ignition of gas cylinders.

Emergency services cordoned off the area, and traffic between Shamora Bay and the village of Shchitovaya was partially restricted.

“The threat has been neutralized,” officials stated.

Tightened security and conflicting accounts

Local media and Telegram channels, including VChK-OGPU and Vladivostok1.ru, reported heavy police and military presence in the area. Roads were blocked, vehicles inspected, and helicopters were seen flying before the blasts.

Witnesses described the removal of large, tarp-covered objects—possibly military vehicles—under guard. The Telegram channel The True Story reported that the location is used for loading and unloading military equipment for naval deployment.

According to Radio Svoboda, Desantnaya Bay may also house a training ground for the Pacific Fleet’s naval infantry, which has taken part in combat operations against Ukraine.
