Earlier, the head of the secretariat of the country's defense industry, Ismail Demir, said that the Turkish side was considering Russia's proposal for the supply of fighters, but a decision has not yet been made.

Also, Russian Deputy Prime Minister Yuri Borisov said that Turkey showed a "genuine interest" in the purchase of Russian Su-35 and Su-57 fighters.

He noted that there is a high probability of concluding a new contract with Turkey for the supply of Russian anti-aircraft missile systems (SAM) following the S-400 systems already acquired by Ankara.

In an interview with Nation News, military expert Boris Rozhin praised the statement by Assistant Chief of Staff of the British Air Force Julian Ball that the S-400 air defense system is the most dangerous type of Russian weapon.
