The Turkish president says he will teach the Dutch about diplomacy after his ministers are barred.
Turkish President Recep Tayyip Erdogan has warned the Netherlands it will “pay the price” for harming ties after two of his ministers were barred.
Mr Erdogan said: “We will teach them international diplomacy. ”
The two ministers were blocked from addressing Turkish expatriates in Rotterdam on Saturday, with one of them escorted to the German border.
The Dutch government said such rallies would stoke tensions days before the Netherlands’ general election.
The ministers were seeking support among expatriate voters for a referendum on expanding Turkish presidential powers.
Fatma Betul Sayan Kaya, Turkey’s family minister, had arrived by road on Saturday but was denied entry to the consulate in Rotterdam and was taken to the German border by Dutch police.
Foreign Minister Mevlut Cavusoglu tried to fly in but was refused entry.
Water cannon and riot police on horseback were deployed to disperse about 1,000 people protesting outside the Turkish consulate in Rotterdam overnight.
Turkey’s relations with several EU countries are in the spotlight ahead of the referendum:
Mr Erdogan focused his rhetoric on the Netherlands on Sunday, accusing the Dutch of “sacrificing Turkish-Dutch relations for the sake of the elections on Wednesday”.
Threatening to travel to rallies abroad himself, he added: “The West has clearly shown its true face in the last couple of days. What we have seen… is a clear manifestations of Islamophobia.
“I have said that I had thought that Nazism was over, but that I was wrong. Nazism is alive in the West,” he said.
But he thanked France for allowing Mr Cavusoglu to travel to the northern city of Metz to address the rally there on Sunday, saying: “France was not deceived by such games. ”
At a protest outside the Dutch consulate in Istanbul, the Dutch flag was briefly replaced with a Turkish one, which was later removed.
The Netherlands’ foreign ministry responded by saying that the Turkish authorities were responsible for the safety of Dutch diplomats in Turkey.
Dutch PM Mark Rutte said Mr Erdogan’s comment on Saturday that the Dutch were “Nazi remnants and fascists” was “unacceptable”.
The Dutch government is facing a severe electoral challenge from the anti-Islam party of Geert Wilders in its election on Wednesday.
Reports say the owner of a venue in the Swedish capital, Stockholm, has also cancelled a pro-Erdogan rally on Sunday that was to have been attended by Turkey’s agriculture minister.
Sweden’s foreign ministry said it was not involved in the decision and that the event could take place elsewhere.
Turkey is holding a referendum on 16 April on whether to turn from a parliamentary to a presidential republic, more akin to the United States.
If successful, it would give sweeping new powers to the president, allowing him or her to appoint ministers, prepare the budget, choose the majority of senior judges and enact certain laws by decree.
What’s more, the president alone would be able to announce a state of emergency and dismiss parliament.
In order to get it passed, Mr Erdogan needs the votes of citizens living within Turkey and abroad.
There are 5.5 million Turks living outside the country, with 1.4 million eligible voters in Germany alone – and the Yes campaign is keen to get them on side.
So a number of rallies have been planned for countries with large numbers of expat voters, including Germany, Austria and the Netherlands.
However, Mr Erdogan’s supporters have found themselves blocked from holding these rallies.
Many of the countries, including Germany, have cited security concerns as the official reason.
Austrian Foreign Minister Sebastian Kurz said Mr Erdogan was not welcome to hold rallies as this could increase friction and hinder integration.
Many European nations have also expressed deep disquiet about Turkey’s response to the July coup attempt and the country’s perceived slide towards authoritarianism under President Erdogan.
Germany in particular has been critical of the mass arrests and purges that followed – with nearly 100,000 civil servants removed from their posts.
