ANOTHER mysterious death has rocked Russia as a tank boss suddenly died just one day after Vladimir Putin cancelled a meeting with him.

General Alexei Maslov, 69, suddenly fell ill and died on Christmas Day just after Putin axed a visit to the tank firm where he worked in Uralvagonzavod.

Maslov was the former head of the Russian ground forces and an ex-ambassador to Nato - and was reportedly not known to have any health problems before his sudden death.

Putin then suddenly cancelled his visit even as his convoy was in place and the roads had been cleared of snow.

It fuelled speculation amid rumours Vlad is attempting to dodge questions on his failing war in Ukraine or is sick.

No reason was given for the cancellation - and the mystery deepens further after the death of General Maslov.

Maslov’s death also follows the “sudden death” of Alexander Buzakov, 65, general director of Admiralty Shipyards in St Petersburg, in charge of building new submarines.

The FSB security service had formed an “investigative group” into the two deaths, reported Russian Telegram channel Redacted number 6.

Buzakov had been healthy the day before he died, and “nothing had been heard about Maslov's health problems” before he died, said the channel.

And it follows the mysterious deaths of at least 10 oligarchs and Putin critics....
