Viewers Corner News correspondent in Ankara reported that Turkish military will start testing Russian-made S-400 air defense systems despite the United States threats of sanctions. Russia delivered two S-400 defense systems this year and they were deployed at an airbase in the outskirts of Ankara. The United States said that Russian-made S-400 air defense systems delivered to Turkey pose a threat to NATO security and as a result, Turkey was suspended from participating in the multinational F-35 fighter jet program.
