Turkey's President has warned the Netherlands will "pay the price" after two of his ministers were barred from addressing Turkish expats in the country.
In response Turkish President Recep Tayyip Erdogan decried the Dutch as "Nazi remnants", while Prime Minister Binali Yildirim has threatened "harsh" retaliation.
Protests against the cancellation of the rally in the Netherlands have been taken place in Rotterdam and Istanbul.
Turkey should apologise for comparing the Dutch to Nazis, the Netherlands' Prime Minister has said.
Mark Rutte added that the latest comments by Turkish President Recep Tayyip Erdogan, in which he accused the Netherlands of acting like a "banana republic" and said it will pay the price for its "shameless" treatment of Turksih ministers, are "unacceptable" and are not helping to de-escalate tensions between the two countries.
Mr Rutte added that if Turkey continues on its current path then the Netherlands would be forced to consider it's response.
The row began on Saturday when a Turkish rally in Rotterdam was cancelled and the country's foreign minister's plane was not allowed to land in the Netherlands.
German Chancellor Angela Merkel has backed the Netherlands in its diplomatic fight with Ankara while the EU has urged Turkey to calm down.
A diplomatic row between Turkey and the Netherlands has broken out but what is it all about?
Turkey's president described the Dutch as "Nazi remnants" and "fascists" after his Foreign Minister's plane was denied landing permission.
