The head of the Wagner force said Saturday he has ordered his mercenaries to halt their march on Moscow and retreat to their field camps in Ukraine to avoid shedding Russian blood.
The announcement from Yevgeny Prigozhin appeared to defuse a growing crisis. Moscow had braced for the arrival of the private army led by the rebellious commander. And President Vladimir Putin had vowed he would face harsh consequences.
Prigozhin said that while his men are just 200 kilometers (120 miles) from Moscow, he decided to turn them back to avoid "shedding Russian blood."
According to the Economic Times, he didn't say whether the Kremlin has responded to his demand to oust Defense Minister Sergei Shoigu. There was no immediate comment from the Kremlin.
The announcement follows a statement from the office of Belarusian President Alexander Lukashenko saying that he had negotiated a deal with Prigozhin after previously discussing the issue with Putin.
Prigozhin has accepted Lukashenko's offer to halt the Wagner group's advance and further steps to de-escalate the tensions, Lukashenko's office said, adding that the proposed settlement contains security guarantees for Wagner troops. It didn't elaborate.
Moscow on Saturday erected checkpoints with armored vehicles and troops on its southern edge, Red Square was shut down and the mayor urged motorists to stay off some roads as the Russian capital braced for the arrival of a private army led by a rebellious mercenary commander.
President Vladimir Putin vowed harsh consequences for organizers of the armed uprising led by his onetime protege, Yevgeny Prigozhin, who brought his forces out of Ukraine, seized a key military facility in southern Russia and advanced toward Moscow.
Prigozhin's actions represented the most significant challenge to Putin's leadership in his more than two decades in power.
In a televised speech to the nation, Putin called the rebellion a "betrayal" and "treason."
"All those who prepared the rebellion will suffer inevitable punishment," Putin said. "The armed forces and other government agencies have received the necessary orders."
Authorities declared a "counterterrorist regime" in the capital and its surrounding region, enhancing security and restricting some movement.
On the southern outskirts, troops erected checkpoints, arranged sandbags and set up machine guns.
Moscow Mayor Sergei Sobyanin warned that traffic could be restricted in parts of the capital. He declared Monday a non-working day for most residents.
Crews dug up sections of highways to slow the march of the Wagner mercenary army. Access to Red Square was closed, two major museums were evacuated and a park was shut.
Prigozhin's private army appeared to control the military headquarters in Rostov-on-Don, a city 660 miles (over 1,000 kilometers) south of Moscow that runs Russian operations in Ukraine, Britain's Ministry of Defense said.
Wagner troops and equipment also were in Lipetsk province, about 360 kilometers (225 miles) south of Moscow, where authorities "are taking all necessary measures to ensure the safety of the population," said regional Gov. Igor Artamonov, via Telegram. He did not elaborate.
The dramatic developments came exactly 16 months after Russia launched its full-scale invasion of Ukraine, Europe's largest conflict since World War II, that has killed tens of thousands, displaced millions and reduced cities to rubble.
Ukrainians hoped the Russian infighting would create opportunities for its army to take back territory seized by Russian forces.
Ukrainian President Volodymyr Zelenskyy said Moscow was suffering "full-scale weakness" and that Kyiv was protecting Europe from "the spread of Russian evil and chaos."
The Federal Security Service, or FSB, called for Prigozhin's arrest Friday night after he declared the armed rebellion.
Prigozhin said his fighters would not surrender, as "we do not want the country to live on in corruption, deceit and bureaucracy."
"Regarding the betrayal of the motherland, the president was deeply mistaken. We are patriots of our homeland," he said in an audio message on his Telegram channel.
Prigozhin's private army has been fighting alongside regular Russian troops in Ukraine. His goals weren't immediately clear, but the rebellion marks an escalation in his struggle with Russian military leaders, whom he 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," Prigozhin said.
Prigozhin said he had 25,000 troops under his command and urged the army not to offer resistance.
He posted video of himself at the military headquarters in Rostov-on-Don and claimed 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.
"We didn't kill a single person on our way," Prigozhin said in one of his several messages posted as the day went on, adding that his forces seized the military headquarters "without a single gunshot." His claims could not be independently verified. The Russian authorities haven't reported any casualties so far, either.
The rebellion comes as Russia is "fighting the toughest battle for its future," Putin said, with the West piling sanctions on Moscow and arming Ukraine.
"The entire military, economic and information machine of the West is waged against us," Putin said.
