Turkey: We'll use S-400 despite US threats

Turkey will use the S-400 missile defense system it has bought from Russia despite the US threat of sanctions, a senior defense official said Saturday, according to AFP.

Ankara and Washington have been at loggerheads over Turkey’s purchase of the S-400 system, which the United States says is not compatible with NATO defenses and poses a threat to Lockheed Martin’s F-35 “stealth” fighter jet.
