The wreckage was discovered near the village of Burdanovka, about 20 miles from Irkutsk, which is 2,600 miles east of Moscow.
The aviation authority said there were no survivors, but gave no figure for the number of victims. Earlier, the Interfax news agency had reported 133 passengers and 10 crew were on board.
