Poland, Lithuania and Latvia have grown increasingly worried since the Russian mercenaries arrived in Belarus.
NATO allies located along the alliance’s eastern front are growing increasingly worried about the presence of Russia-linked Wagner Group mercenaries in Belarus, where some have been deployed since a short-lived mutiny in Russia in June.
Poland, Lithuania and Latvia – members of NATO and the European Union which border Belarus – had already been on alert since large numbers of migrants and refugees began arriving at their borders from Belarus two years ago.
They have accused Belarus’s President Alexander Lukashenko, an ally of Russia, of opening the migration route in an act of “hybrid warfare” aimed at creating instability in the West.
Now concerns have grown further since the Wagner troops began arriving in Belarus after their short-lived mutiny in Russia.
Poland’s Prime Minister Mateusz Morawiecki said on the weekend that about 100 Wagner fighters in Belarus had approached the border with Poland, specifically a strategically sensitive area known as the Suwalki Gap.
“Now the situation becomes even more dangerous,” Morawiecki told reporters. “This is certainly a step towards a further hybrid attack on Polish territory.”
An incident on Tuesday added further to the concerns, with two Belarusian helicopters entering Polish air space at low altitude while carrying out exercises.
Poland’s defence ministry reported that incident to NATO, which said on Wednesday that it is monitoring the situation.
“NATO is closely tracking the situation along its eastern borders, including yesterday’s incident where two Belarusian military helicopters briefly crossed into Polish airspace at low altitude,” a NATO official said on customary condition of anonymity.
“We are in close contact with the Polish authorities on this matter, and we will continue to do what is necessary to ensure all alliance territory remains secure,” the official added.
Poland, Lithuania and Latvia say they have been deploying more troops and equipment to their borders.
Guntis Pujats, head of Latvia’s State Border Guard, told Latvian media on Wednesday that security risks in the immediate vicinity of the Belarus border have been high since Minsk started using migrants as a tool of “hybrid warfare”, and that the risks have grown with the arrival of the Wagner Group.
He said border guards have started training a special task force in response.
Lithuania’s President Gitanas Nauseda said this week that it would be tempting for the Wagner Group to use its presence near the Lithuanian border “for various provocations”.
“So I think the threat is serious,” Nauseda said during a visit on Monday to a site on the border with Belarus where seven Lithuanian officers were murdered by Soviet paratroopers 32 years ago.
Others have suggested that one should not overestimate the capabilities of the armed group.
Laurynas Kasciunas, chairman of the Seimas National Security and Defence Committee, told reporters that Wagner mercenaries in Belarus with their current combat power do not pose a conventional military threat.
Whether they pose a great threat in the future, he said, “will depend on further scenarios, how they are armed and their orders”.
In Poland, some critics of the government believe that it is overstating the threat in order to present itself as tough on security before parliamentary elections this fall.
Polish opposition leader Donald Tusk accused the ruling party of using Wagner to stoke fear before the elections, something the party has denied.
Some Poles also faulted the authorities for refusing to initially acknowledge that the Belarusian helicopters had entered Poland’s airspace on Tuesday.
At first, the military insisted that the Belarusian aircraft had not entered Poland. But after local residents posted photos on social media of aircraft with Belarusian insignia several kilometres from the border inside Poland, the defence ministry put out a statement saying it was true.
The US ambassador to the United Nations, Linda Thomas-Greenfield, said earlier this week that the United States views the Wagner Group – whose forces have fought in Ukraine and also operated in Africa – as a threat.
“We have seen their malign efforts on the continent of Africa. So we certainly worry that this group, at the behest of the Russian government – because they do not work independently of the Russian government – is a threat to all of us,” Thomas-Greenfield told reporters on Monday.
“And we have to ensure that the message is clear that any attacks by the Wagner Group will be seen as an attack by the Russian government.”
