A son of Sergei Ivanov, the Kremlin chief of staff and a longtime ally of Russian President Vladimir Putin, has died at age 37.
Aleksandr Ivanov died "tragically" on November 3, state-controlled Vneshekonombank, where he was deputy chairman, said in a statement.
It did not say how or where he died.
The bank posted the statement on its website after Russian channel Dozhd TV and "Forbes" magazine quoted sources as saying Ivanov died in the United Arab Emirates.
Some reports said he drowned.
Ivanov was at the center of a scandal after a car he was driving hit and killed an elderly woman in Moscow in 2005.
Initial charges of reckless endangerment leading to a fatality were later dropped, and he was never held responsible.
Sergei Ivanov, a former KGB officer, is one of Putin's closest associates and has been Kremlin chief of staff since December 2011.
