Turkey has said it will retaliate in the "harshest ways" to the Dutch government after the Netherlands barred Turkey's foreign minister from entering the country.
Prime Minister Binali Yildirim threatened on Sunday: "This situation has been protested in the strongest manner by our side, and it has been conveyed to Dutch authorities that there will be retaliation in the harshest ways... We will respond in kind to this unacceptable behaviour."
