"Suddenly, I hear recently, Poland went berserk that allegedly some detachment is coming here, as many as 100 people," Belarusian leader Alexander Lukashenko said, APA reports citing Reuters.
"No Wagner detachments of 100 people moved here. And if they did, then only to transfer their military experience to (Belarusian) brigades concentrated in Brest and Grodno."
Lukashenko has helped Putin in the Ukraine war by letting him launch it in part from Belarusian territory and allowing the use of his bases to train Russian troops.
He has not committed his own troops to the war but has said they will benefit from training by Wagner, which took part in some of the fiercest battles of the conflict.
"I have to teach my military, because an army that does not fight is half an army," he said.
On Saturday, Polish Prime Minister Mateusz Morawiecki said a group of 100 Wagner fighters had moved closer to the Belarusian city of Grodno near the Polish border, describing the situation as "increasingly dangerous".
Lukashenko, in his latest comments, appeared at first to deny that, then immediately to row back on the denial.
