Turkish President Recep Tayyip Erdogan on Sunday accused the Netherlands of "sacrificing Turkish-Dutch relations" and warned, "you will pay the price."
It was the latest in the ongoing escalation of tension between the two countries leading up to Dutch elections Wednesday. Erdogan was also critical of Germany last week, making accusations about Nazism in Germany as well as in the Netherlands.
Dutch elections: What you need to know
"I thought Nazism was over but I was wrong," Erdogan said at the International Goodness Awards ceremony in Istanbul.
"What we saw in the last couple of days in Germany and Netherlands are the reflections of Islamophobia."
On Saturday, protests broke out in Rotterdam and in the major Turkish cities of Ankara and Istanbul. Earlier, the Netherlands had blocked Turkey's foreign minister from landing in the country to speak at a political rally.
Erdogan reacted angrily to the news, comparing the Dutch government to Nazis.
Speaking at the ceremony in Istanbul, Erdogan said: "They are timid and cowards. They are Nazi remnants and fascists."
'We will respond in the heaviest way'
Earlier, Erdogan had angered German Chancellor Angela Merkel by making similar remarks about Nazism in her country.
The Dutch government said the minister's flight permit was revoked amid concerns over public order at an expected large gathering of Turkish expatriates.
"We protested that situation heavily and we told our Dutch counterparts that we will respond in the heaviest way," Turkish Prime Minister Binali Yildirim said in a statement.
Turkish politicians want to speak in European cities with large numbers of expatriates in advance of an April 16 referendum vote on the Turkish constitution.
The referendum would turn Turkey's parliamentary system into a presidential one, effectively consolidating the power of three legislative bodies into one executive branch under Erdogan.
Some 1.5 million Turkish nationals living in Germany are eligible to vote in the referendum, according to Turkish news agency Anadolu.
But the authorities in several countries have blocked their plans.
The Dutch will vote Wednesday in national elections that have focused heavily on the issue of immigration from Muslim countries.
Far-right politician Geert Wilders praised the decision to bar the Turkish minister from speaking in Rotterdam, crediting the influence of his party, the Party For Freedom, or PVV, for the move
