Very good article on the history of the war.

Like Mr. Putin, whose spies have been accused of poisoning and assassinating perceived traitors all over the world, Mr. Prigozhin has said that treachery is the worst sin any Russian can commit. He has proposed setting up his own Gestapo-like police force to hunt down the disloyal, including, he has said, Russian businessmen “who leave our country in their business jets.”
The fate of Mr. Nuzhin serves as a grisly warning.
Mindful of the pressures on prisoners of war and the risks they face, The Times has chosen to withhold their names. And, as with the other people we interviewed, we use documents and other evidence to vet their claims.
In Mr. Nuzhin’s case, we did not publish our interview with him, but he also spoke to Ukrainian media, which broadcast portions of his account. Soon after, he was released in a prisoner swap — and ended up back in the hands of Wagner.
He then appeared in a video on a pro-Russian Telegram account. In it, Mr. Nuzhin’s head was taped to a block. Looming over him was a man in camouflage, holding a sledgehammer.
“I woke up in this basement, where I was told that I will be judged,” Mr. Nuzhin says in the video, his voice dry and gravelly. The sledgehammer then swings down and crushes his skull.
Shortly after, Mr. Prigozhin released a statement endorsing Mr. Nuzhin’s murder.
“Nuzhin betrayed his people, betrayed his comrades, betrayed them consciously,” the statement said. “He planned his escape. Nuzhin is a traitor.”
A day later, asked about the video on a conference call with journalists, Mr. Peskov said, “It’s not our business.”
