Russia's Investigative Committee says it has confirmed Yevgeny Prigozhin, the founder and head of the mercenary force Wagner who led a short-lived armed rebellion against Russia's military, was killed in a plane crash.
Committee spokeswoman Svetlana Petrenko said in a statement released on Sunday that after forensic testing, all 10 bodies recovered at the site of Wednesday's crash were identified, and their identities "conform to the manifest".
Russia's civil aviation authority earlier this week said Prigozhin, 62, and some of his top lieutenants, were on the list of the passengers and crew members on board the plane.
All seven passengers and three crew died when the plane plummeted from the sky halfway between Moscow and St Petersburg, Prigozhin's hometown.
Two months ago, Prigozhin mounted a daylong mutiny against Russia's military, leading his mercenaries from Ukraine toward Moscow. President Vladimir Putin decried the act as "treason" and vowed punishment for those involved.
Instead, the Kremlin quickly cut a deal with Prigozhin to end the armed revolt, saying he would be allowed to walk free without facing any charges and to resettle in Belarus.
Questions have remained, however, about whether Prigozhin eventually would face a comeuppance for the brief uprising that posed the biggest challenge to Putin's authority of his 23-year rule.
A preliminary US intelligence assessment concluded that an intentional explosion caused the plane to go down.
As suspicions grew that the Russian president was the architect of an assassination, the Kremlin rejected them as a "complete lie".
These people dared to challenge Putin. All of them are dead
One of the Western officials who described the initial assessment said it determined that Prigozhin was "very likely" targeted and that an explosion would be in line with Putin's "long history of trying to silence his critics".
Prigozhin's second-in-command, Dmitry Utkin, as well as Wagner logistics mastermind Valery Chekalov, also were killed in the crash. Utkin was long believed to have founded Wagner and baptised the group with his nom de guerre.
The fate of Wagner, which until recently played a prominent role in Russia's military campaign in Ukraine and was involved in a number of African and Middle Eastern countries, has remained uncertain.
After the mutiny, the Kremlin said Prigozhin would be exiled in Belarus, and his fighters were offered three options: to follow him there, retire or enlist in Russia's regular army and return to Ukraine, where Wagner mercenaries had fought alongside Russian troops.
Several thousand Wagner mercenaries opted to move to Belarus, where a camp was erected for them south-east of the capital, Minsk.
