The Chairman of Russia’s Lukoil giant, Ravil Maganov, has died. He died after falling from a hospital window in Moscow.
The company confirmed his death but said only that Maganov passed on following a severe illness.
Maganov is now the latest of several high-profile business executives to die in mysterious circumstances.
Investigations have begun as authorities say they are working at the scene to establish what led to his death.
Shortly after Russia invaded Ukraine, the Lukoil board called for the conflict to end as soon as possible, expressing its sympathy for the victims of the tragedy.
