Latvia, Lithuania & Poland concerned about risk of Wagner 'serial killers' in neighbouring Belarus

European Union countries bordering Belarus on Thursday asked for more solidarity from the bloc and NATO over the presence of "serial killers" from the Wagner mercenary group and the risk of "infiltration" into their countries.

"We keep a very wary eye on everything that occurs in Belarus with [Wagner chief Yevgeny] Prigozhin there and an unknown number of very trained and skilled fighters who presumably will be joining him," Latvian Prime Minister Arturs Krišjānis Kariņš told reporters upon arrival at a two-day summit of EU leaders in Brussels.

"That does potentially pose a threat. The threat would probably not be a frontal military threat, but the threat of attempted infiltration into Europe for unknown purposes. So that means we need to heighten our border awareness and make sure that we can control that," he added. 

Minsk has previously been accused of weaponising its border with EU member states by deliberately bringing thousands of mostly Middle Eastern foreign migrants to the border in retaliation for EU sanctions against Minsk over fraudulent elections and the subsequent violent repression of pro-democracy demonstrations. 

Poland, which also borders Belarus, has meanwhile said that the EU should pay to strengthen security at the border.

"European solidarity means supporting countries threatened with destabilisation," Deputy Foreign Minister Pawel Jablonski said on Thursday on public radio. 

Belarusian President Alexander Lukashenko confirmed on Tuesday that Prigozhin had indeed arrived in his country and said that a former military base had been made available for any Wagner fighters who wished to join him.

Prigozhin's exile in Belarus is reportedly part of a deal the Wagner chief has struck with Russian President
