TALLINN, Estonia (AP) — Russia’s civil aviation agency says mercenary leader Yevgeny Prigozhin was on a plane that crashed north of Moscow, killing all 10 people aboard. Prigozhin led a brief armed rebellion against the Russian military earlier this year. Wednesday’s crash immediately raised suspicions since the fate of the founder of the Wagner private military company has been the subject of intense speculation ever since he mounted the mutiny. At the time, President Vladimir Putin denounced the rebellion as “treason” and a “stab in the back” and vowed to avenge it. But the charges against Prigozhin were soon dropped, and the Wagner chief was allowed to retreat to Belarus, while reportedly popping up in Russia from time to time.
