A poll conducted by Interfax shows that all leading Russian tour operators have suspended the sale of tours to Turkey at the recommendations of the Foreign Ministry and the Federal Agency for Tourism (Rosturizm).

"The sale of tour products on the Turkey track has been suspended due to the report issued by Rosturizm on November 24, 2015," Marina Makarkova, head of the public relations department at Coral Travel, said.

"Yes, we have suspended sales," Anna Podgornaya, general director of the company Pegas Touristik, said.

The press service for the company TUI Russia told Interfax that sales of Turkey as a seasonal destination were completed in October and early booking has not opened yet.

The tour companies Biblio Globus and TEZ Tour have reported the suspension of the sale of tours to Turkey on their websites, saying this decision was made due to the statement by Russian Foreign Minister Sergei Lavrov and the recommendation issued by Rosturizm.

Irina Tyurina, press officer for the Russian Union of Travel Industry, earlier told Interfax there may be up to 10,000 Russian tourists in Turkey now and tour operators had sold 4,000-5,000 tour packages for the period until the New Year holidays.

Russian Foreign Minister Sergei Lavrov said on Tuesday the Foreign Ministry recommends that Russian citizens refrain from visiting Turkey for tourism purposes because the level of the terrorist threat in Turkey is not lower than in Egypt. Afterwards, Rosturizm recommended that tour operators suspend the sale of tours to Turkey, including through third countries.

The news of the crash of a Russian Sukhoi Su-24 plane in the territory of Syria as a result of an attack by the Turkish Air Force came on Tuesday morning.
