If prosecutors do not accept the invitation, the Belarussian authorities will unilaterally decide how to proceed with meetings with high-ranking officials, Lukashenko said.
“If they do not show up, we will resolve the issue without them,” the president was quoted as saying by BelTA.
33 Russian citizens accused of preparing terrorist attacks were arrested in Belarus last week.
Minsk claims that the detainees are fighters of the Russian military company Vagner, which are preparing to carry out terrorist attacks in order to destabilize the situation before the presidential elections in Belarus scheduled for August 9.
The Belarussian authorities also believe that several of the detainees have taken part in hostilities in eastern Ukraine as part of Moscow-funded terrorist gangs.
Moscow claims that the detainees are employees of a private security company on their way to a third country. Moscow stressed that the detainees did not violate Belarusian law and should be released immediately.
A spokesman for Russian President Vladimir Putin identified the third country as Turkey.
In turn, a high-ranking diplomat told the Russian media that the detainees planned to go to Latin America.
Ukrainian President Volodymyr Zelensky said in a telephone conversation with Lukashenko on Wednesday that detainees accused of involvement in hostilities in Ukraine should be extradited to Ukraine, Zelensky’s office said.
