Speakers of the parliaments of Latvia (Edvards Smiltēns), Lithuania (Viktorija Čmilytė-Nielsen), and Estonia (Lauri Hussar) have stated that the recent Wagner Group's coup is another confirmation of the unpredictability of the situation in Russia.

They noted in their joint statement that the presence of Wagner private military company (PMC) in Belarus could destabilise the security situation on NATO and EU's eastern borders.

"While the recent "march of justice" on Moscow by Prigozhin's Wagner mercenary group is Russia's internal matter, it is yet another sign of the unpredictability of Russia," their statement reads.

They point out the need to continue strengthening collective defence and deterrence and border security in NATO's eastern flank bordering Russia and Belarus. They expect concrete measures to achieve this goal to be presented at the NATO Summit in Vilnius.

"We reiterate our condemnation of Lukashenko's regime in Belarus for supporting Russia's war against Ukraine. The harbouring of the terrorist organisation Wagner group by Belarus is unacceptable and we call for further strengthening sanctions against Belarus," the speakers stated.

They also repeated their call for the European Union to include the Wagner mercenary group in the list of persons, groups and entities involved in terrorist acts (EU terrorist list) not least for the violence and instability the group spreads on the African continent and elsewhere.

Furthermore, the speakers urged NATO leaders to initiate a meaningful process of inviting Ukraine to the Alliance at the July summit in Vilnius.

They expressed confidence that in the long-term perspective, Ukraine's security would be best ensured through collective defense within NATO. They emphasized the need to continue supporting Ukraine in its prolonged struggle for freedom and territorial integrity, together with international partners and allies.

The speakers also called on establishment of the special international tribunal under the auspices of the UN General Assembly to prosecute the crime of aggression committed by the Russian leadership.

Previously, Lithuanian President Gitanas Nauseda warned about the risks posed to Lithuania's security by the Wagner Group in Belarus.

US President Joe Biden believes that Russian President Vladimir Putin has "definitely" weakened after the coup attempt.
