Police in Russian Federation detained more than 4,800 people in several cities and blocked off the center of Moscow on Sunday in a massive clampdown on protests. Hundreds were detained by police. "I'm so exhausted of the complete chaos of those in power", said Evan, one of the protesters.
Police have warned that Sunday's protests have not been authorised and will be considered illegal and broken up as they were last weekend.
Lawyer Dmitry Djulai said on Facebook that investigators later detained Vasilyeva for 48 hours in connection with alleged and unspecified violations of COVID-19 rules.
"Trying to lock up every critic in the country is a losing game - the Russian authorities should instead recognize how much the rights to freedom of peaceful assembly and expression mean to a growing number of Russians, and allow people to express their opinions without fear of retaliation", she said.
Blue underwear and toilet brushes, snowball barrages and snow graffiti - Russia's protest movement in support of jailed Kremlin critic Alexei Navalny has seen demonstrators get creative.
Numerous demonstrators expected they would face consequences for attending the rallies, which saw more than 4,000 people detained nationwide.
His dramatic return to Moscow despite the obvious threat of arrest and the second straight weekend of protests at his jailing pose a challenge for Putin who has dominated the Russian political landscape for over two decades.
Some of the biggest rallies were held in Novosibirsk and Krasnoyarsk in eastern Siberia and Yekaterinburg in the Urals.
Mr Navalny's wife Yulia posted a picture of her family on Instagram on Sunday, urging supporters to make their voices heard.
The protests followed a week of crackdown by authorities targeting supporters of Navalny.
Mr Navalny was detained earlier this month when he returned from Germany - where he'd been recovering from nerve agent poisoning.
AFP journalists saw dozens of protesters detained and taken into police vans.
At one point, a column of protesters marched towards the prison in northern Moscow where Navalny is being held, chanting "Let him go!"
Demonstrators in Moscow chanted "Aqua discotheque!" - a reference to one of the fancy amenities at the residence that also features a casino and a hookah lounge equipped for watching pole dances. The Kremlin likes to say that these protests are small and that the majority is for Putin. Navalny was jailed two weeks ago after returning from Germany, where he had been receiving treatment after being poisoned with a chemical weapon. The president denies the claim and Arkady Rotenberg, his former judo opponent, now says he owns it.
When he returned to Russian Federation in January, Navalny was jailed for 30 days after Russia's prison service alleged he had violated the probation terms of his suspended sentence from a 2014 money-laundering conviction that he has rejected as political revenge. Can you give us an update on the nature of their call?
Authorities have requested that suspended sentence now be converted to real prison time, raising the possibility that Navalny could be behind bars for up to three and a half years.
At the White House briefing on Tuesday, press secretary Jen Psaki told reporters that President Biden planned to speak with Russian President Vladimir Putn about issues that included the SolarWinds hack, reports of Russian bounties on American soldiers and interference in the 2016 election.
