The SBU said this in a statement posted on Telegram, Ukrinform reports.
As a result of a multi-stage special operation, SBU officers neutralized a subversive and intelligence group of the Main Directorate of the General Staff of the Armed Forces of the Russian Federation (better known as GRU), the report said.
The culprits were preparing to kill Reznikov, Budanov, as well as a well-known Ukrainian activist.
Russian "curators" offered the culprits a reward of $100,000 to $150,000 for the murder of each of them.
It was established that the group had been formed by employees of the Russian military intelligence to carry out subversive activities in Ukraine. It included a resident of temporarily occupied Luhansk, who as part of the illegal armed formations of the terrorist organization "LNR" took an active part in combat operations against Ukraine's ATO forces in the east of the country.
