Erdogan says Turkey continues S-400 payments, criticizes U.S. stance

President Tayyip Erdogan said on Friday that Turkey was continuing to make payments under its deal with Russia to buy S-400 missile defense systems and the United States had not presented the same terms when it offered to sell the rival Patriot missile system.The United States' arguments are very wrong.Turkey's planned purchase of the Russian system has put it at odds with NATO ally the United States.
