Vice President Oktay slams U.S. for sanctions

"Those who threaten us with sanctions should know that the threats would motivate us about domestic design and production. In the near future, Turkey will be one of the leading countries, producing its own air defense systems, F-35-like fighter aircraft, unmanned ground defense vehicles," Oktay said.

U.S. President Donald Trump on Friday signed the National Defense Authorization Act (NDAA), which includes sanctions on Turkey for purchase of the Russian weapon system. (ILKHA)
