The Ukrainian partisan group ATESH said on Sunday it carried out a sabotage operation that disrupted Russian military communications in the Bryansk region, about 100 kilometers (60 miles) from the Ukrainian border.
Bryansk is a region in western Russia that borders both Ukraine and Belarus. Its southern edge touches Ukraine’s Chernihiv and Sumy regions, making it a key rear area for Russia’s war effort. Moscow uses the region to support logistics and launch drone and missile attacks against northern Ukraine.
In a statement, ATESH said its agents destroyed a communications tower used to coordinate Russian border troops and occupation forces.
The strike reportedly hit command centers linked to Russia’s Border Service, the 84th Engineering and Airfield Battalion, and a unit of the National Guard (Rosgvardiya).
ATESH claimed the attack caused chaos in Russia’s command system and temporarily disrupted control of a key border area. The group said the loss of communications made it harder for Russian forces to respond to potential threats.
“The enemy cannot feel safe even deep behind the front lines,” ATESH said, adding that its network continues to target Russian military infrastructure.
Russian officials have not commented on the claim.
