WARSAW, Poland

Latvia on Sunday warned of "possible unpredictable developments" in the region, as manifested by the Wagner paramilitary group's recent armed rebellion against the Russian state.

Stressing that the rebellion was Russia's internal affair, Latvian Foreign Ministry spokesperson Diana Eglite told Anadolu that her country will remain vigilant as it cannot overlook the likelihood of such unpredictable developments being repeated.

Latvia is also providing Ukraine with every possible support against Russian aggression, she added.

Wagner accused Russian forces of attacking its fighters Friday and the group subsequently crossed from Ukraine into the Russian city of Rostov-on-Don.

In response, the Federal Security Service in Russia initiated a criminal case against Wagner for "armed mutiny." Russian President Vladimir Putin labeled Wagner's uprising as an act of "treason."

Wagner head Yevgeny Prigozhin said his fighters would proceed to Moscow, prompting the Kremlin to enhance security measures across various regions of the country.

He later claimed his fighters decided to turn back to avoid bloodshed when they were 200 kilometers (124 miles) from Moscow, while Belarusian President Alexander Lukashenko said he held talks with the Wagner head with Putin's accord, and Prigozhin accepted a de-escalation deal.
