Also on Thursday, the tickets sales for the Olympics events were opened. The prices of 42 percent of all the tickets, according to the steering committee head Dmitry Chernyshenko, are under $100.

"The cheapest ticket for any sport competition will be sold for 1,500 rubles (about 50 dollars)," Chernyshenko told reporters in Sochi, adding the prices have been calculated on the basis of average prices for the similar sporting events and were confirmed by the IOC.

The cheapest price for the opening ceremony is an equivalent of $200 and of $150 for the closing ceremony, according to the official ticketing website.
