The chairman of Russia's oil giant Lukoil Ravil Maganov has died after falling from a window in a Moscow hospital. Maganov, 67, committed suicide, state-run agency TASS reported. This is the sixth incident involving high-profile Russian energy executives dying under murky circumstances this year. Maganov began working for a company that would later become Lukoil in the 1980s and is credited with giving the corporation its modern name. In 1993, he joined the board of directors and was appointed its chairman in 2020. He was also the company's first executive vice president. Maganov's brother Nail is the CEO of another large oil producer, Tatneft, in the Tatarstan region. Maganov was a close associate of one of Lukoil's founders, billionaire Vagit Alekperov, who stepped down from his position as CEO in April 2022 days after the U.K. and the EU sanctioned him.
