A Russian plane with eight people on board crashed overnight and all passengers and crew were feared dead, Russian media reported on Sunday.
The Cessna light aircraft came down just outside Moscow and burst into flames when it hit the ground, news agencies reported.
RIA Novosti news agency reported that among the passengers was Igor Olshansky, an assistant to a deputy in the State Duma lower house of parliament.
The identity of the other passengers was not known.
Aircraft crashes are fairly common in Russia. On Friday, four people died when a Mi-2 helicopter crashed in the Vologda region north of Moscow.
