The chairman of Russian oil and gas giant Lukoil has died after falling out of the window of a hospital in Moscow, according to Russian state media.

“The man fell out of the sixth-floor window and died as a result of his injuries,” a source told TASS.

Lukoil confirmed the death of its chairman on Thursday in a statement published on its website.

Ravil Maganov “passed away following a severe illness,” Lukoil said, making no mention of a fall.

“For many years, Ravil Maganov led LUKOIL’s upstream block as a First Executive Vice President. In 2020, he was named Chairman of PJSC LUKOIL Board of Directors.

“Thanks to Ravil Maganov’s managerial talent, LUKOIL evolved from a small oil production group to one of the world’s leading energy companies in next to no time, increased its oil and gas production manifold, developed from scratch new oil and gas provinces in the Caspian and Baltic seas, successfully launched superviscous oil projects in the Republic of Komi, introduced advanced technological solutions to support production at mature fields in West Siberia, joined consortiums in the most promising oil regions of the world,’’ the statement by Lukoil said.

Lukoil, Russia’s second biggest oil and gas company, made headlines in March when it called “for the soonest termination of the armed conflict” in Ukraine.

“We express our sincere empathy for all victims, who are affected by this tragedy,” the company’s board of directors said in a statement to shareholders, staff and customers at the time. “We strongly support a lasting ceasefire and a settlement of problems through serious negotiations and diplomacy.”

The firm produces more than 2% of the world’s crude oil and employs over 100,000 people.

RIA Novosti quoted a law enforcement source Thursday as saying Maganov “most likely committed suicide.”

“Investigating authorities are working on the spot to establish the causes of the incident,” the source told RIA.
