At least 5,045 people were detained, with more than 1,600 in Moscow alone. That marks a record-high in detentions since 2011, when OVD-Info, an independent site that monitors arrests, started recording such figures.
Among those detained on Sunday was Navalny’s wife, Yulia Navalnaya, who was later released.
Navalny’s team has said that the “next stop” for demonstrations will be on Tuesday, when a Moscow court considers Navalny’s case on fraud charges and establishes whether his suspended sentence should be replaced with a real jail term.
“Today’s protest is over, but we continue to fight for Alexey Navalny’s freedom,” the team posted on their Telegram channel at 6:20 p.m. local time.
Navalny was detained on January 17, moments after arriving in Moscow, following months of treatment in Germany after being poisoned in August 2020 with nerve agent Novichok. He blamed the poisoning on the Russian government, an allegation the Kremlin has repeatedly denied.
Protests across country
Earlier on Sunday, supporters of Navalny said they were planning protests in at least 120 cities across the vast country, starting at noon local time in each location.
Protesters in Moscow planned to march down to the Matrosskaya Tishina detention center where Navalny is being held in custody, according to a CNN team on the ground. Local authorities were closing metro stops one after another leading up to the detention center in the city’s northeastern Sokolniki neighborhood.
Navalnaya was detained “during a peaceful walk” by police officers who did not identify themselves or provide any reason for the detention, according to Vyacheslav Gimadi, head of the legal department of Navalny’s Anti-Corruption Foundation (FBK).
She has since been released, Grimadi told CNN.
Live video feeds and social media videos Sunday showed crowds of people gathering in a number of cities, chanting “Putin is a thief,” in reference to Russian President Vladimir Putin.
In the Russian city of Novosibirsk, in Siberia, live video showed police detaining drivers who were honking their car horns in support of the protesters. In response, demonstrators were heard chanting: “Let them go!”
People could be seen with their elbows linked, forming chains, chanting “Freedom!” and “Give back our money!” as they stood in front of the city hall in the center of Novosibirsk. Rows of riot police were standing in front of them.
Protesters marching along the snowy streets could be heard chanting: “Russia without Putin!” and “one for all, and all for one.”
Russia’s Ministry of Internal Affairs earlier warned Russian citizens not to take part in the “unauthorized” protests. “The Ministry of Internal Affairs of Russia calls on citizens to refrain from participating in unauthorized protests,” the ministry said in an Instagram post.
Russian federal law requires organizers to file an appeal with local authorities at least 10 days in advance to obtain permission to hold a protest.
Police detentions in Moscow
Navalny’s team announced via its social media accounts new gathering points for protesters in the cities of Moscow and St. Petersburg after Russian authorities blocked off certain streets and metro stations ahead of the rallies.
Earlier in the week Navalny’s team said demonstrators in Moscow would gather in Lubyanka Square, home to the headquarters of the Russian Federal Security Service (FSB).
Russia has denied involvement in the case.
Security forces could be seen out in force in the city’s streets, including Lubyanka Square, on Sunday.
CNN’s team in Moscow saw police detaining protesters in an apparent attempt to stop the protest in the capital getting under way.
Rebecca Ross, spokewoman for the US Embassy in Moscow, urged Russia to respect international human rights as protests take place across the country.
“We renew our call for Russia to release those detained for exercising their human rights,” he continued, referring to Navalny.
The Russian Foreign Ministry in turn accused the US of “gross interference” in the internal matters of Russia, saying Blinken was supporting the “violation of law” in a statement posted on its official Facebook page.
“There is no doubt that actions aimed at encouraging protests are part of a strategy to hold Russia back,” the ministry said. “We demand an end to interference in the internal affairs of sovereign states.”
Authorities announced ahead of Sunday’s protests that certain streets in the center of Moscow would be closed off, seven metro stations would be shut and that no alcohol could be sold in glass containers all day.
Additionally, the Moscow mayor’s office said that cafes, restaurants and other catering facilities would be closed in the city center on Sunday, according to Russian state media agency TASS.
“If we are silent, then tomorrow they will come after any of us,” she wrote in a post accompanying the photo, referring to Russian authorities.
“In a 16-storey bunker with an aqua disco, a random frightened person is the one who decides our fate — he might decide to jail one and to poison another one,” she wrote.
FBK executive director Vladimir Ashurkov, who signed the letter, told CNN on Saturday that the foundation was calling on the United States to put pressure on Putin to release Navalny.
Journalist and campaigner Zhanna Nemtsova, the daughter of murdered Russian opposition politician Boris Nemtsov, said Sunday she believed Kremlin critic Alexey Navalny “will be locked away in prison for many years.”
“The only way to support Alexey Navalny is to take to the streets,” Nemtsova, who has joined the protests in Moscow, told BBC radio. “We have no choice, and it is what can partially guarantee Navalny’s security while he’s in prison,” she said.
“Lots of people have nothing to lose, especially young people,” Nemtsov told the program, when asked about the hopes of the thousands of people who have been protesting across Russia since Navalny’s arrest.
“We are experiencing another economic downturn. In many cases, if you want to pursue a decent career, you have to be loyal to the government. Of course, it is very depressing for many people,” she added.
Nemtsova’s father, former deputy prime minister Boris Nemtsov, was assassinated on a Moscow bridge within sight of the Kremlin in 2015. Nemtsov was then considered the most visible leader of the Russian opposition. Five Chechen men were handed prison sentences for his killing in 2017.
