Yevgeny Prigozhin, the leader of a Russian mercenary group, was presumed deceased following a fatal crash of a private jet, in which he was registered as a passenger. The crash occurred north of Moscow, resulting in no survivors. He had recently made a brief and unsuccessful attempt to rebel against President Vladimir Putin, and was one of Vladimir Putin’s enemies.

Yevgeny Prigozhin, aged 62, led a mutiny against Russia’s military leadership on June 23-24, an action President Vladimir Putin believed could have pushed Russia into civil war.

There are others who opposed Putin or his interests and faced uncertain fates:
