Overbearing in life but discreet in death, Russian mercenary chief Yevgeny Prigozhin was buried quietly in a leafy cemetery on the outskirts of St. Petersburg on Tuesday, six days after he was killed in an unexplained plane crash.

The funeral took place away from the glare of the media and in stark contrast to the brazen, self-publicizing style with which Prigozhin had fanned his reputation, in Russia and far beyond, for ruthlessness and ambition.

"The farewell to Yevgeny Viktorovich took place in a closed format. Those who wish to say goodbye may visit Porokhovskoye cemetery," his press service said in a short post on Telegram.
