The head of the security service did not specify from which country the individuals come from, noting that issues relating to espionage are connected "with foreign policy and relations between states."
He also said that Ukrainian citizen Pavel Sharoyko, earlier convicted in the republic for spying, could be pardoned.
"The question of pardoning Sharoyko is being considered," the chairman said, adding that a pardon commission would decide the fate of the Ukrainian citizen.
On February 19, 2018, the Supreme Court of Belarus sentenced Sharoyko to 8 years in prison for espionage.
