Russia has sent new components of its S-400 air-defense system to a military air base near the Turkish capital, Ankara.
Turkey’s Defense Ministry tweeted on July 14 about the landing of a fifth and sixth Russian cargo planes at Murted air base, saying two more planes were expected within hours.
Turkey received the first three shipments of S-400 components on July 12 and a fourth shipment on July 13, defying threats of sanctions from the United States.
Washington and its allies consider the missile system to be incompatible with NATO systems and a threat to the F-35 fighter jets.
