Turkey expresses "unease" to US over its removal from F-35 programme - CNN Turk

President Tayyip Erdogan's spokesman expressed "unease" on Thursday in a telephone call with U.S. National Security Advisor John Bolton over Washington's decision to remove Turkey from its F-35 program, broadcaster CNN Turk said.

Following the delivery of parts of the Russian S-400 air defense system to Turkey, the United States said on Wednesday it was removing Turkey from the F-35 fighter jet program.

Erdogan's spokesman Ibrahim Kalin said relations between the two NATO allies could not remain healthy with such unilateral impositions, CNN Turk reported.
