The minister of foreign affairs, Jan Lipavský, says Czechia is closely monitoring the situation in Russia.

In view of the continuing invasion of Ukraine and the possible threat of deterioration in the security situation in Russia itself, he said on Saturday that a warning against travelling to the country remained in place.

President Putin said in a TV address that an uprising by the Wagner mercenary army would be punished.

What did Prigozhin do?

The dramatic turn of events began on Friday when Prigozhin openly accused Russia’s military of attacking a Wagner camp and killing a “huge amount” of his men. He vowed to retaliate with force, insinuating that his forces would “destroy” any resistance, including roadblocks and aircraft.

“There are 25,000 of us and we are going to find out why there is such chaos in the country,” he said.

Prigozhin later rowed back on his threat, saying his criticism of the Russian military leadership was a “march of justice” and not a coup – but by that point he appears to have already crossed a line with the Kremlin.

The crisis then deepened as Prigozhin declared his fighters had entered Russia’s Rostov region and occupied key military installations within its capital. That city, Rostov-on-Don, is the headquarters for Russia’s southern military command and home to some one million people.

Prigozhin released a video saying his forces would blockade Rostov-on-Don unless Defence Minister Sergei Shoigu and Russia’s top general Valery Gerasimov come to meet him.

Prigozhin has spent months railing against Shoigu and Gerasimov who he blames for Moscow’s faltering invasion of Ukraine.

How did Russia respond?

Hours later Putin made an address to the nation that illustrated the depth of the crisis he now confronts.

“Those who carry deliberately on a path of treason, preparing an armed rebellion when you were preparing terrorist attacks, will be punished,” Putin said.

The Russian President said, “any internal turmoil is a deadly threat to our statehood for us as a nation; it is a blow to Russia for our people and our actions to protect our homeland. Such a threat will face a severe response,” he added.

Russia’s Defense Ministry denied attacking Wagner’s troops, calling the claim “informational propaganda.”

And the Federal Security Service (FSB), Russia’s internal security force, also opened a criminal case against Prighozhin, accusing him of calling for “an armed rebellion.”

“Prigozhin’s statements and actions are in fact calls for the start of an armed civil conflict on the territory of the Russian Federation and are a stab in the back of Russian servicemen fighting pro-fascist Ukrainian forces,” an FSB statement said, calling for Wagner fighters to detain their leader.

Russian officials meanwhile appeared to take no chances with security measures stepping up in Moscow, according to Russian state media TASS.

Moscow Mayor Sergei Sobyanin said Saturday on Telegram that “anti-terrorist” measures to strengthen security were being carried out in the capital as a result of “incoming information.”

Social media posts showed military vehicles were seen driving around the main streets of the Russian capital in the early hours of Saturday.
