President Vladimir Putin has vowed to punish the organisers of an armed rebellion in Russia after mercenary chief Yevgeny Prigozhin led his troops out of Ukraine and into a key southern city.
Mr Putin denounced the uprising by Wagner Group forces as “a stab in the back”.
It marks the biggest threat to Mr Putin’s leadership in more than two decades in power.
Moscow’s mayor warned on Saturday that traffic could be restricted in parts of Russia’s capital as part of heightened security measures.
Sergei Sobyanin asked the city’s residents to refrain from using their cars during the counter-terrorism operation in Moscow and the surrounding region.
He also declared Monday to be a non-working day for most people, with the exception of public servants and employees of some industrial enterprises.
Andrei Vorobyov, the governor of the region surrounding Russia’s capital, has suspended mass public events outdoors and at educational institutions until July 1.
The private army led by Mr Prigozhin appears to control the military headquarters in Rostov-on-Don, a city 660 miles south of Moscow that runs Russian offensive operations in Ukraine, the UK’s Ministry of Defence said.
The governor of the Lipetsk province said later that the Wagner Group has entered his region, which is about 225 miles south of Moscow.
Authorities “are taking all necessary measures to ensure the safety of the population. The situation is under control”, governor Igor Artamonov said on Telegram.
As the fast-moving events unfolded in Russia, Ukrainian President Volodymyr Zelensky said Moscow is suffering “full-scale weakness”, and that Kyiv is protecting Europe from “the spread of Russian evil and chaos”.
In an address to the Russian nation, Mr Putin called the actions by Mr Prigozhin, whom he did not mention by name, a “betrayal” and “treason”.
The Russian President said: “All those who prepared the rebellion will suffer inevitable punishment.
“The armed forces and other government agencies have received the necessary orders.”
Mr Prigozhin said his fighters would not surrender, as “we do not want the country to live on in corruption, deceit and bureaucracy”.
Everyone who chooses the path of evil destroys himself. Who sends columns of troops to destroy the lives of another country and cannot stop them from fleeing and betraying when life resists. Who terrorizes with missiles, and when they are shot down, humiliates himself to receive…

“Regarding the betrayal of the motherland, the president was deeply mistaken. We are patriots of our homeland,” the Wagner Group said in an audio message on his Telegram channel.
Mr Prigozhin’s private military contractor has been fighting alongside Russian troops in Ukraine.
His goals were not immediately clear, but the rebellion marks an escalation in his struggle with Russian military leaders, whom he has accused of botching the war in Ukraine and hobbling his forces in the field.
“This is not a military coup, but a march of justice,” Mr Prigozhin said.
💬 #Putin: Today, Russia is waging a tough struggle for its future, repelling the aggression of neo-Nazis & their patrons.
❗️ Any internal revolt is a deadly threat to our statehood. Our actions to defend the Fatherland from this threat will be harsh.

He confirmed on Saturday that he and his troops had reached Rostov-on-Don after crossing the border from Ukraine.
Mr Prigozhin posted a video of himself at the military headquarters in Rostov and claimed that his forces had taken control of the airfield and other military facilities in the city. Other videos on social media showed military vehicles, including tanks, on the streets.
The Wagner Group chief said his forces faced no resistance from young conscripts as they crossed into Russia, saying his troops “aren’t fighting against children”.
“But we will destroy anyone who stands in our way,” he said in one of a series of video and audio recordings posted on social media beginning late on Friday.
“We are moving forward and will go until the end,” he added.
The rebellion comes at a time when Russia is “fighting the toughest battle for its future”, Mr Putin said, as Western governments heap sanctions on Moscow and arm Ukraine.
“The entire military, economic and information machine of the West is waged against us,” the Russian leader said.
Russia’s security services, including the Federal Security Service (FSB), called for Mr Prigozhin’s arrest after he declared an armed rebellion late on Friday.
In a sign of how seriously the Kremlin takes the threat, authorities declared a “counter-terrorist regime” in Moscow and its surroundings, allowing restricted freedoms and enhancing security in the capital.
It is not immediately clear how Mr Prigozhin was able to enter the southern Russian city or how many troops he had with him.
Mr Prigozhin said he wanted to punish defence minister Sergei Shoigu after he accused Russian government forces of attacking Wagner field camps in Ukraine with rockets, helicopter gunships and artillery. He claimed that “a huge number of our comrades got killed”.
He added that Wagner’s forces had shot down a Russian military helicopter that fired on a civilian convoy, but there was no independent confirmation of that.
Mr Prigozhin alleged that Gen Valery Gerasimov, chief of the general staff, ordered the attacks following a meeting with Mr Shoigu, where they decided to destroy Wagner.
The defence ministry has denied attacking the Wagner camps.
Mr Prigozhin said he had 25,000 troops under his command and urged the army not to offer resistance.
After Mr Putin’s address, in which he did not mention concrete steps to suppress the rebellion but rather called for unity, officials and state media personalities sought to reiterate their allegiance to the Kremlin and urged Mr Prigozhin to back down.
Vyacheslav Volodin, speaker of the lower house of parliament, said legislators “stand for the consolidation of forces” and support Mr Putin, adding that “Wagner fighters must make the only right choice: to be with their people, on the side of the law, to protect the security and future of the Motherland, to follow the orders of the commander-in-chief”.
Foreign ministry spokeswoman Maria Zakharova echoed Mr Volodin’s sentiment, saying in a Telegram post: “We have one commander in chief. Not two, not three. One.”
Ramzan Kadyrov, the strongman leader of the Chechnya region who used to side with Mr Prigozhin in his criticism of the military, also expressed his full support of Mr Putin’s “every word”.
While the outcome of the confrontation is still unclear, it appears likely to hinder Moscow’s war effort as Kyiv’s forces probed Russian defences in the initial stages of a counter-offensive.
The dispute, especially if Mr Prigozhin were to prevail, also could have repercussions for Mr Putin and his ability to maintain unity.
The Wagner forces have played a crucial role in Ukraine, capturing the eastern city of Bakhmut, an area where the bloodiest and longest battles have taken place.
However, Mr Prigozhin has increasingly criticised the Russian military’s top brass, accusing it of incompetence and of starving his troops of munitions.
Mr Zelensky noted the rebellion in his Telegram channel and said “anyone who chooses the path of evil destroys himself”.

He added: “For a long time, Russia used propaganda to mask its weakness and the stupidity of its government. And now there is so much chaos that no lie can hide it.
“Russia’s weakness is obvious. Full-scale weakness. And the longer Russia keeps its troops and mercenaries on our land, the more chaos, pain and problems it will have for itself later.”
Mr Prigozhin’s actions could have significant implications for the war. Orysia Lutsevych, the head of the Ukraine Forum at the Chatham House think tank in London, said infighting between the defence ministry and Wagner will create confusion and potential division among Russian forces.
The Wagner chief, whose feud with the defence ministry dates back years, had refused to comply with a requirement that his forces sign contracts with the ministry before July 1.
He said on Friday he was ready for a compromise, but “they have treacherously cheated us”.
Col Gen Sergei Surovikin, the deputy commander of the Russian forces in Ukraine, urged Wagner troops to stop any move against the army, saying it would play into the hands of Russia’s enemies who are “waiting to see the exacerbation of our domestic political situation”.
The US and the leaders of European countries including Italy and Poland have said they are monitoring developments closely, while Estonia, which borders Russia, stepped up border security.
