Polish Prime Minister Mateusz Morawiecki reportedly warned Saturday that a group of about 100 Russian Wagner mercenaries were moving through Belarus closer to Poland’s border.

Poland, both a member of the European Union and NATO, has accused Belarus of wielding "hybrid warfare" in facilitating illegal migration at the Polish border, suggesting Minsk has encouraged migrants to fly into Belarus under the false promise of easy access to the European Union, the BBC reported. 

During a press conference at an arms factory in Gliwice, southern Poland, where Leopard tanks used by the Ukrainian army are being repaired, Morawiecki said about 100 Wagner mercenaries had moved close to the Suwalki Gap, according to The Associated Press. The region is a strategic stretch of Polish territory situated between Belarus and Kaliningrad, a Russian territory separated from the mainland. The Suwalki Gap also runs along Poland’s 60-mile-long border with fellow European Union member state Lithuania. 

Morawiecki claimed that the mercenaries might falsely present themselves as Belarusian border guards to help migrants move across to the EU.

"Now the situation becomes even more dangerous," Morawiecki said, adding that "this is certainly a step toward a further hybrid attack on Polish territory."

Thousands of Russian mercenaries have reportedly relocated to Belarus since last month’s short-lived rebellion orchestrated by Wagner boss Yevgeny Prigozhin, who made his first public sighting since the failed-coup just days ago while attending an Africa summit in Russia celebrating the Niger coup. 

Belarusian President Alexander Lukashenko told Russian President Vladimir Putin during a conversation last weekend that he would keep the Wagner mercenaries in central Belarus.

"They are asking to go west... to go on a trip to Warsaw," Lukashenko told Putin, referencing Poland’s capital city. "But of course, I am keeping them in central Belarus, like we agreed." 

Poland’s Interior Ministry said Thursday that Poland, Lithuania and Latvia could make the joint decision to shut down their borders with Belarus should incidents with Wagner mercenaries unfold on the frontier. 

The Poland-Belarus border has already been a tense place for a couple of years, ever since large numbers of immigrants from the Middle East and Africa began arriving. Poland's government has accused Russia and Belarus of using the migrants to destabilize Poland and other EU countries and has responded by building a high wall along part of its border with Belarus.

Kentucky Congressman James Comer, R., joined Fox News' 'Sunday Morning Futures' to discuss the latest in the Biden Family business dealings investigation and former Hunter Biden associate Devon Archer's testimony before the House Oversight Committee, telling host Maria Bartiromo that Archer has the 'opportunity' to share the truth and be a 'hero.'

MARIA BARTIRTOMO: What are you expecting to get from Devon Archer tomorrow? Let's talk about that on the record testimony. 

CRITICS MOCK USA TODAY TWEET LAMENTING HUNTER BIDEN'S 'FOIBLES': 'DEFINITION OF GASLIGHTING'

REP. JAMES COMER: … Yeah, well, I don't want to put words in Devon Archer's mouth, but I'll say this. He has an opportunity to come tomorrow to the House Oversight Committee and tell the truth. He has an opportunity to be a hero, like the two whistleblowers were, like the judge in Delaware was, who rejected the sweetheart plea deal from the Department of Justice to Hunter Biden. Devon Archer could be in that category of Americans that just come and tell the truth. That's all we want. We know that Devon Archer was on the board of Burisma with Hunter Biden. We know that Devon Archer has met and communicated many, many times with Joe Biden about Burisma and other things. So this is going to be an opportunity for Devon Archer, just to tell the truth. We have other bank statements that we've obtained that we have questions about pertaining to countries that we believe Archer may have knowledge of. 

… So, you know, my hat's off to Devon Archer when he shows up tomorrow. I know it's tough. I know he's been intimidated by the Biden legal team, but hopefully he saw what happened in that courtroom in Delaware last week. And there are good people in the justice system. And we saw that judge stand up and reject the obvious sweetheart plea deal that the Department of Justice gave the President's son. I know that the President's legal team has been telling our witnesses that they don't need to cooperate with the committee, that nothing's going to happen to the Bidens. I don't think that's true. And I think we saw that play out in the courtroom next week. So we're excited about Devon Archer. and I appreciate his willingness to come.
