The president of Lithuania Gitana Nausenda stated on Sunday that the NATO he will have to “strengthen” his eastern wing if Yevgeny Prigozhin, the leader of the Russian paramilitary organization Wagner, will be in Belarus.

The leader of the Baltic country, which borders Russia and Belarus and will host a NATO summit next month, made the remarks after a Lithuanian security council meeting on Wagner’s failed mutiny against Kremlin.

After Prigozhin ordered his troops to withdraw from the Rostov on Saturday, Moscow announced that Wagner’s captain would leave Russia for Belarus and face no prosecution.

“If Prigozhin or a part of her Wagner group found in Belarus without definite plans or intentions, it simply means that we will have to further strengthen the security of our eastern border,” Gitanas Nausenda told reporters.

“I’m not just talking about Lithuania today, but undoubtedly about NATO as a whole,” he added.

Nausteda clarified that Lithuania will allocate more resources to its intelligence services to assess the “political and security aspects of Belarus.”

He also said that Lithuania still plans to host the NATO summit next month and that security measures around that summit do not need to change after the recent events in Russia.

Nowseda stated that the Russian president Vladimir Putinafter Wagner’s armed rebellion, will probably face even greater difficulties, adding: “The king is naked.”

The insurgency by the Wagner paramilitary mercenary group is Russia’s most serious security crisis and the biggest challenge Vladimir Putin has faced since he came to power in late 1999.
