A Ukrainian mathematician committed suicide in Moscow. The Russian Federal Security Service prevented him from leaving Russia for Ukraine.

This was reported by Konstantin's acquaintances lawyer Dmitry Zakhvatov and journalist Alexander Chernykh.

He left a suicide note-post in which he wrote that he was leaving his life because he could not bear the horror of what was happening.

After Russia's full-scale invasion of Ukraine, the mathematician tried to leave Russia, but he was detained at a bus station and arrested for 15 days in 2 days on a trumped-up case under the administrative article "minor hooliganism" for violating public order at the station.

"I was on my way to defend my country, to defend it from someone who wanted to take it away from me," Olmezov wrote. And he added that unfreedom was worse for him than death.

In his personal Telegram channel, Konstantin also described in great detail what was happening to him in the last days of his life and how he felt after Russia's invasion of Ukraine.

He had been living in Russia since 2018 and was doing additive combinatorics, a branch of mathematics not represented in Ukraine. He also wrote poetry. In a suicide message, Konstantin wrote:

"On February 26, I tried to leave the territory of Russia. It was partly a stupid act, but only to the extent that it was ill-conceived. I do not regret it, but I only regret that I did not do it on February 23rd, when I had every reason to.

...I was arrested on boarding the bus. I think this was due to my bad tongue and to a man with whom I had shared my plans in a fit of temper. Being arrested, I felt that my freedom had been taken away forever, and I told the FSB straight to my face what I thought about what was going on. It was stupid, but it had to be. It was the last thing I could hit them with, and I punched as hard as I could. I was even amused by how helplessly they tried to respond to me, how uninspired they were in repeating the crudest stamps of propaganda with a face that was completely innocent.

...I hurt for each side in this war, but I see with my own eyes who is defending their land and who is invading another's. I see with my own eyes who is defending the right to responsibility for his own life and who is justifying his own degradation.

...When, in the twenty-first century, an army attacks a completely alien, completely non-threatening country in the middle of the night. And every soldier understands what he is doing, and pretends not to. When that country's minister says "we didn't attack," and the journalists broadcast it. And every journalist understands that this is a lie, and pretends not to understand. When millions of people are watching this and realize that what is happening will be on their conscience and history and pretend they had nothing to do with it. When black is called white and soft is called bitter, and not in a conspiratorial whisper, and without a wink, but as if from themselves. ...When force once again claims to be the main source of truth, and treachery and hypocrisy the main source of calm. When all this is going on around me, I lose all hope for a different way of humanity.

...I'm kind of ashamed of my Ukrainian friends. Believe me, I have never wished or done harm to Ukraine and have always kept in mind the willingness to leave if things start to go the way they are now. Unfortunately, it just didn't work out for me, I just didn't approach the matter skillfully enough...I had a naïve belief that legal sensitivity in dealing with Ukrainians implies the ability to pull out at some critical moment. I stuck my head too far down the tiger's throat. This is my second big mistake; I have a lot to pay for. Every shell that falls on the streets of Kiev hurts me. Reading the bulletins, I imagine the views of these streets, neighborhoods. From the first day until this day I was with you with all my heart, though it is clear that this did not save anyone...

...And finally, of course, a poem:

Do Russians want "no war" posters?

Ask a riot policeman in armor,

Ask the subway diver,

Ask that to the man who clings to his throne.

Do Russians want broken cities?

Ask it to the trains that are jammed.

Do Russians want ruined hospitals?

Ask that of dried-up baby eye sockets.

Do Russians want to make a difference?

Ask the rest of the media.

Do Russians want to end Nazism?

Ask that of students with a "chick".

Your business card will be this creepy year,

A truly unshakable people,

Ready to bathe in blood or shit,

But only if there are no "no war" posters.

Хотят ли русские плакатов "нет войне"?

Спроси об этом у омоновца в броне,

Спроси об этом у ныряющих в метро,

Спроси об этом у вцепившегося в трон.

Хотят ли русские разбитых городов?

Спроси об этом у забитых поездов.

Хотят ли русские разрушенных больниц?

Спроси у высохших младенческих глазниц.

Хотят ли русские хоть что-то изменить?

Спроси об этом у оставшегося СМИ.

Хотят ли русские искоренить нацизм?

Спроси об этом у студентов с буквой "цыц".

Твоей визиткой станет этот жуткий год,

Воистину непоколебленный народ,

Готовый хоть в крови купаться, хоть в говне,

Но лишь бы не было плакатов "нет войне".
