A private jet crashed in Russia on Wednesday, killing all 10 people on board, emergency officials said.

Mercenary chief Yevgeny Prigozhin was on the passenger list, but it was not immediately clear if he was on board.

Prigozhin’s fate has been the subject of intense speculation ever since he mounted a short-lived mutiny against Russia’s military leadership in late June.

The Kremlin said the founder of the Wagner private military company, which fought alongside Russia’s regular army in Ukraine, would be exiled to Belarus.

But the mercenary chief has since reportedly popped up in Russia, leading to further questions about his future.

A plane carrying three pilots and seven passengers that was en route from Moscow to St Petersburg went down more than 60 miles north of the capital, according to officials cited by Russia’s state news agency Tass.

It was not clear if Prigozhin was among those on board, though Russia’s civilian aviation regulator, Rosaviatsia, said he was on the manifest.

Russia’s state news agency RIA Novosti reported, citing emergency officials, that eight bodies were found at the site of the crash.

Flight tracking data reviewed by The Associated Press showed a private jet registered to Wagner that Prigozhin had used previously took off from Moscow on Wednesday evening and its transponder signal disappeared minutes later.
