 Russian President Vladimir Putin is aware of the developments surrounding Wagner head Yevgeny Prigazin and all necessary measures are being taken, Dmitry Peskov, head of Russian President's Press Service stated on Friday. The remarks come after Yevgeny Prigazin said that the Wagner base in Ukraine was attacked upon Russian Defense Minister Sergei Shoigu's order and that a large number of people died during the strike. Prigazin highlighted that an army of 25,000 set out to punish Shoigu. Russia's Rostov city is reportedly already under the siege. Meanwhile, Russian Federal Security Service has launched a criminal case over incitement to a military uprising. The Russian National Anti-Terrorism Committee has described the information circulated on behalf of Prigazin as groundless and called for an end to illegal activities.
