Russian opposition politician Ilya Yashin, who is serving an 8 1/2-year prison term for his criticism of Moscow's invasion of Ukraine, has been sent to solitary confinement for five days, his Telegram channel said on December 4. Officially, Yashin was "punished" for refusing to work on the construction of a new prison barrack. But Yashin said the issue of his work on the construction site was raised after he challenged the Kremlin in video testimony in a hearing last week. After the hearing a Moscow court fined him for failing to follow "foreign agent" requirements.
