I'm skeptical. I keep reading this exact headline about Putin, Kadyrov and Lukashenko. I'm not saying it's not true this time, but there have been a lot of false reports in regards to this.
I think the Luka news about hospitalization were true, though. I might be wrong, but IIRC, it was verified by several sources. Presumably he was in the hospital for "normal" reasons, and got better.
