Turkish President Recep Tayyip Erdogan confirmed on Friday that Turkey had been testing the S-400 air defense system it bought from Russia, adding that the objection from NATO ally United States on the issue did not matter.
Washington says Ankara's purchase of Russian S-400 systems compromise NATO defenses, and has threatened sanctions. An apparent firing test of S-400s test last week prompted a furious response from the State Department and Pentagon. (Reuters)
