Turkey considers other countries’ calls against using S-400 surface-to-air missile systems purchased from Russia as unacceptable, Turkish Foreign Minister Mevlut Cavusoglu said during his visit to Athens on Monday.
"The S-400 will be 100% under our control. We sent our technical specialists [to Russia] and there will be no Russian military experts in Turkey. In this regard, we view the demands by other countries ‘for not using’ [S-400s] as inadmissible," the TV Channel TRT quoted the Turkish foreign minister as saying.
Meanwhile, U.S. Undersecretary of State Wendy Sherman said in an interview with CNN Turk that the United States had offered Turkey an alternative to the purchase of Russian-made S-400 air defense systems. However, the US diplomat did not elaborate on it.
