Turkey's opposition Nationalist Movement Party (MHP) leader Devlet Bahçeli on Saturday said Ankara's purchase of Russian S-400 missile defense system was a "done deal".
"Turkey will buy S-400 and deploy them. It is a done deal and the discussion is over. The U.S. should think about the rest," Bahçeli said during an event in Istanbul.
Bahçeli added the U.S.' efforts to take Turkey under blockade over S-400 is not a "friendly attitude".
Tensions between the U.S. and Turkey have simmered over Ankara's purchase of the S-400s.
Washington claims the purchase will jeopardize Turkey's role in the F-35 fighter jet program and has threatened sanctions.
Turkey has said there is no conflict between the S-400 and the F-35 and has called for a working group to clarify the issue.
