The first shipment of Russian-made S-400 air defence system components continued to arrive by plane at an airfield near Ankara on Friday. The equipment deliveries are part of an agreement between Russia and Turkey to modify the Turkish air defence system, the Russian Defence Ministry has said.
According to the ministry, the delivery of other parts of the system will take place in accordance with the contract and within the timeframe agreed by both sides.
The US has strongly urged NATO member Turkey to pull out of the deal, threatening to impose sanctions if it fails to comply.
