Belarus has arrested 33 Russian mercenaries allegedly plotting to destabilize the country ahead of next month's presidential election.

Belarus' KGB security service said the detained men were members of the Wagner group, a shadowy private military firm reportedly controlled by an ally of Russian President Vladimir Putin which promotes Moscow's interests in Ukraine, Syria, Libya and a number of other countries.

The shock announcement is just the latest twist in an extraordinary election campaign that has seen President Alexander Lukashenko, who has dominated Belarus for nearly three decades, jail his key would-be rivals ahead of the vote.

Here’s all you need to know and wanted to ask about the allegations:

How were the Wagner mercenaries caught?

State news agency Belta said the authorities had received information about the arrival of 200 fighters in Belarus "to destabilize the situation during the election campaign."

The ex-Soviet country's security services on Wednesday arrested a group of 32 Russian fighters as well as one other man in a different location.

On Thursday morning, Belarus security council chief Andrei Ravkov said a criminal probe had been launched and that the men face charges of preparing "terrorist acts." He said "a search is going on" to find the others, complaining that it was "like looking for needles in a haystack."
Did Belarus authorities know about their presence in advance?

Descriptions of the men indicate that they were not trying to keep a low profile. Their behavior was "uncharacteristic for Russian tourists" because they didn't drink and their "uniform military-style clothing" drew attention, Belta said.

Analysts say it would have been virtually impossible for Lukashenko to be unaware of the Wagner mercenaries' presence.

“Lukashenko, of course, was aware of why the Wagner fighters were in Minsk and where they were heading,” military correspondent Semyon Pegov wrote.

Are these people really Russian mercenaries?

Based on the information that has been revealed, yes. Belta released the names of all 33 men who were detained and Belarussian television aired several of their alleged passport photographs.

“Our own independent research shows that they really are Wagner fighters,” Denis Korotkov, a journalist with the Novaya Gazeta newspaper who specializes in covering the Wagner Group, told The Moscow Times. “We have our own documents identifying a third of the soldiers. Nine names on the list are not known to us yet. Around 10 of them fought in Syria, and around the same number fought in Ukraine. It is harder to provide definite evidence of their involvement in African wars.”

What is Ukraine's role?

Ukraine's relations with Russia have been strained since 2014, when Moscow annexed the Crimean peninsula and conflict broke out between Ukrainian forces and pro-Russian separatists in the country's east.

Ukraine's security service said Thursday it will seek to extradite the detained Russian fighters from Belarus. Authorities in Belarus later asked Kiev to verify whether any of the detained Russians were involved in crimes committed on Ukrainian territory.

How has Russia responded?

The Russian Embassy in Minsk said Wednesday it had been notified of the detention of 32 Russian nationals.

On Thursday, the Kremlin denied trying to "destabilize" Belarus.

Experts have so far pushed forward three main theories as to what happened:

The Wagner soldiers were on their way to a third country from Belarus

During the coronavirus pandemic, Belarus has kept its borders open and operated international flights as usual. Russians have used Belarus as a springboard to travel abroad as their own country has grounded international flights.

This is “the most logical version” of events, Korotkov said. “It is not the usual route used by Wagner, but during the pandemic, it might be useful to use the country as a transit hub for a small number of soldiers.”

The men may have been on their way to Sudan, where the Wagner Group is reportedly active. Video footage showed Sudanese currency among the detained men's belongings.

Military expert Pavel Luzin questioned whether the Wagner Group would use Belarus as a transport hub.

“I don't really see how that would work,” he told the Republic news website. “Wagner is all under the roof of military intelligence. It is convenient for them to work from Russia. There are many quiet places here, many airports, and much easier. I'm not sure that the Russian military intelligence is so at ease in Belarus to start working with mercenaries on the spot there.”

On Thursday, the Russian ambassador to Minsk said the men were in Belarus on their way to a third country and had stayed in a hotel after missing their flight.

The whole thing is orchestrated (with or without Russian approval) to postpone the elections in Belarus

Lukashenko is facing the toughest re-election bid of his 26 years in power in the Aug. 9 vote.

Protests swept the country after his main election rivals were jailed or barred from running. As public discontent builds over his policies and handling of the coronavirus pandemic, protesters have rallied behind the wife of a jailed opposition candidate.

Analysts say the detentions might give Lukashenko the excuse to either further clamp down on the opposition or cancel the election altogether.

At an emergency meeting of all election candidates Thursday morning, Belarus officials said the rest of the 200 Russian militants are still in Belarus and that they are preparing terror attacks, but that the elections aren’t canceled yet.

Belarus investigators on Thursday accused the mercenaries and top Lukashenko critics Sergei Tikhanovsky and Mikola Statkevich of plotting mass unrest ahead of presidential elections. Tikhanovsky, a popular blogger, was jailed last month, preventing him from submitting his own presidential bid. Opposition politician Statkevich was also jailed in the run-up to the election.
