Oleksandr Kostornyi, who was sentenced to 15 years in prison for treason and for adjusting the Russian missile strike on the Yavoriv training ground, died in prison. Information about his death was also shared by Lviv deputy Ihor Zinkevych, writes “Glavkom.”
Oleksandr Kostornyi was a former KGB employee. According to investigators, after the full-scale invasion began he cooperated with Russian intelligence services and passed them information about military sites in the Lviv region.
In particular, on 4 March 2022 he sent representatives of the FSB a map of the Yavoriv training ground with markings of military sites. According to the investigation, this information was used to prepare and adjust the Russian missile strike.
In May 2024 the Halych District Court of Lviv found Kostornyi guilty of treason and sentenced him to 15 years in prison with confiscation of property. The court determined that he had provided the Russian side with information about the locations of military sites, weapons, and critical infrastructure. (Office of the Prosecutor General)
Kostornyi did not admit his guilt. During the trial he claimed that the map he provided supposedly concerned the area where he gathered mushrooms, not a military facility. The appellate court later upheld the verdict. (Suspline Lviv)
Russian forces attacked the Yavoriv training ground in the Lviv region on the morning of 13 March 2022. More than 30 missiles were launched at the International Center for Peacekeeping and Security. Ukrainian air defenses shot down some of them, but several missiles hit the center's territory.
According to information cited in the case files, 64 people were killed as a result of the strike. That figure is also given in materials about the tragedy at the Yavoriv training ground.
It is worth noting that the military counterintelligence of the Security Service detained in the Lviv region a Russian agent who was simultaneously working for the FSB and the Main Intelligence Directorate.
