Turkeys planned deployment of Russian S-400 missile defenses has been delayed by the coronavirus outbreak but will ultimately go ahead, President Recep Tayyip Erdogans spokesman said on Thursday. "There has been a delay because of the coronavirus but it will move forward as it was planned," Ibrahim Kalin told an online meeting hosted by the Atlantic Council. He said Erdogan had told US President Donald Trump several times that he was also interested in purchasing Patriot missiles. The United States has said that Turkey risks US sanctions if it deploys the Russian-made S-400s. Washington has offered to sell Turkey its Patriot missile defense system if Ankara promises not to operate the rival Russian system, Erdogan said last month.
