Alexey Navalny lost consciousness after taking a walk and died, per Russia's Federal Prison Service.
They have a track record of killing and ordering the killing of political opponents, they said.
At least, that is what prison officials said on Friday, announcing the death of Russia's main opposition politician.
Maxim Alyukov, a political sociologist at King's College London with a focus on Russia, said the death was consistent with a "political killing."
