Operatives of GUR successfully executed an operation that disabled key Russian industrial sites in Kaliningrad. 

This information has been confirmed by sources within Ukrainian intelligence. 

The incident occurred on June 14 at approximately 4 AM. 

The special operation took place in Kaliningrad, where Ukrainian agents targeted an electrical substation. 

According to reports, they drained the coolant from the substation's transformer and subsequently set it ablaze. 

As a result, electricity supply to consumers, including Russian military facilities, was completely halted. 

“We reiterate that Russia no longer has a rear, whether in the east, west, or anywhere else in the world. Everything Russian involved in the war against Ukraine will burn, sink, and be destroyed, regardless of its level of protection or location,” emphasized a GUR representative.

The estimated losses for Russia due to this sabotage are nearly 5 million dollars.
