May 5 (UPI) -- Turkey will follow through on its agreement to purchase the S-400 missile defense system from Russia despite U.S. opposition, Turkish Vice President Fuat Oktay said Sunday.
Oktay said that Turkey would not allow the threat of sanctions from the United States to prevent it from purchasing the surface-to-air missile defense system, which U.S. officials have warned aren't compatible with NATO equipment and may compromise U.S.-made Lockheed Martin F-35 fighter jets.
