Wagner chief Yevgeny Prigozhin is still in Russia, Belarus's president said on Thursday, AFP reported.

"As far as Prigozhin is concerned, he is in Saint Petersburg... He is not in Belarus," Alexander Lukashenko told reporters from foreign media outlets.

Lukashenko said that fighters from Prigozhin's Wagner mercenary group have also not moved to Belarus yet.

"At the moment the question of their transfer and set-up has not been decided," Lukashenko said.

"I am absolutely not worried or concerned that we will host a certain number of these fighters here," he added.

"If we need to activate these units, we will activate them immediately and their experience will be very much appreciated."
