Police in St. Petersburg arrested at least 350 anti-war protesters on Wednesday, taking the total number of protesters detained or arrested to 7,624 since the invasion began, according to an independent organization that tracks human rights violations in Russia.

Opposition to Russian President Vladimir Putin’s military operation in Ukraine, although still limited, is coming from some unexpected places.

“If I make any political statement that is unacceptable in Russia it will have very clear implications for the company, for our customers, for our creditors, for our stakeholders,” Fridman said.

Meanwhile, members of Russia’s “intelligentsia” — academics, writers, journalists and others — have issued public appeals decrying the war, including a rare “open letter” to Putin signed by 1,200 students, faculty and staff of MGIMO University, the prestigious Moscow State Institute of International Relations, affiliated with the Ministry of Foreign Affairs, which produces most of Russia’s government and foreign service elite.

The signers proclaim they are “categorically against the Russian Federation’s military actions in Ukraine.”

“We consider it morally unacceptable to stay on the sidelines and keep silent when people are dying in a neighboring state. They are dying through the fault of those who preferred weapons instead of peaceful diplomacy,” the letter says.

The letter is strikingly personal, with signers explaining that: “Many of us have friends and relatives living in the territories where military action is being carried out. But war has come not only to them, war has come home to each of us, and our children and our grandchildren will feel the repercussions. Many generations of future diplomats will have to rebuild the trust in Russia and the good relations with our neighbors that have been lost.”

A representative of MGIMO did not respond to CNN’s request for comment.

But many Russians, in fact, do not fully know what is happening in Ukraine. State-controlled television shows almost no reports of Russian bombing and shelling in Kyiv and other Ukrainian cities, instead it focuses on so-called Ukrainian “nationalists” and “neo-fascists.”

But Russian young people like 25-year-old Arina, who lives in Moscow, is not watching TV — she says she hasn’t watched it in seven years. She’s on the internet, reading blogs and listening to vloggers. She hasn’t taken part in protests yet, but she has seen young people on the street taking part in “silent protests,” sticking “No to War” signs on their backpacks or bags.

She, too, is having difficulty comprehending why this war in Ukraine is happening and what it will mean for her own life as a young Russian.

“It is very difficult to predict anything, of course, the situation is horrible,” Arina, who asked CNN to only use her first name for her safety said. “Among some of my friends, there is a lot of anxiety about the future, a lot of fear, because we don’t know how it will affect us.”

But Arina’s mother sees it completely differently: “My mom believes everything she sees on TV,” Arina says.

“She believes that it was a necessary measure by Putin because there are weapons surrounding the country…there’s a threat from the West, which is why Putin is doing this.”

Arina says she even checked out a guide on a Russian online magazine for students, Doxa, suggesting how young Russians can talk with their parents and others about the war in Ukraine. “We understand how painful it can be when your parents, friends, colleagues, grandfathers and grandmothers turn into supporters of the war,” it reads.

“So we decided to prepare a guide for how to talk about the war with those who justify it. In our guide you’ll find answers to 17 of the most widespread arguments spread by propaganda and most often heard in fights,” it said.

Arina read it just in time. On February 28, the magazine reported that the Russian government agency supervising communications, IT and mass media demanded Doxa remove the guide from its website.

Arina says she and her mother “had a very fierce argument.”

“She just doesn’t accept my position and thinks I’m a pro-Westerner, that I don’t understand anything. She doesn’t believe what I say, I don’t believe what she says…We have very different sources of information: I learn everything from the independent media, which have mostly long been blocked in Russia, and she watches TV.”

As Arina and her friends follow news about Ukraine on social media, they see the revulsion among many in the West toward Putin’s decision to attack Ukraine. Russians, she says, have contradictory, polar-opposite reactions.

“The first one is, everyone says, ‘Yes, we should be ashamed.’ The second one is, ‘No, let’s not be ashamed of ourselves and let’s not pin decisions on ourselves that were not made by us.'”

But both sides agree on one thing, Arina says: They want the international community to know “that the people are not their President, and we didn’t choose this.”
