Turkey’s war of words with the Netherlands has worsened after the Turkish president accused the Dutch of contributing to a massacre of Muslim men at Srebrenica, Bosnia, in 1995.
Dutch UN peacekeepers failed to protect the men from Bosnian Serb forces, who were prosecuted over the massacre.
Recep Tayyip Erdogan said the failure, still a raw nerve in the Netherlands, revealed Dutch “morality” was “broken”.
The Dutch prime minister called the remarks a “vile falsification”.
Mark Rutte told the BBC Mr Erdogan was becoming “increasingly more hysterical hour by hour and I want him to… calm down”.
Turkey is furious that the Netherlands barred Turkish ministers from campaigning among expatriates for its referendum.
It has accused the Dutch of “Nazi” tactics, barred the Dutch ambassador from returning to Ankara, and suspended high-level relations with the Hague in a raft of diplomatic sanctions.
EU foreign policy chief Federica Mogherini has called on Turkey to “refrain from excessive statements and actions that risk further exacerbating the situation”, but her message appears to have little affect.
Turkey called the appeal “worthless”.
Why did the Dutch ban the Turkish rallies?
The spat began when two Turkish ministers were barred from entering the country to attend rallies that were to be attended by ethnic Turks in the Netherlands.
The rallies were called to encourage Turkey’s large expatriate communities in the EU to vote Yes in a referendum on 16 April on expanding the Turkish president’s powers.
The Dutch government decided to block the rallies, citing “risks to public order and security”. Some 5.5 million Turks live outside the country, including an estimated 400,000 in the Netherlands.
While the Dutch position was that the rallies posed a threat to public order, the EU has made very clear its unease over the Turkish referendum itself.
In their statement on Monday, Ms Mogherini and Mr Hahn voiced concern that it could lead to an “excessive concentration of powers in one office”.
Mr Erdogan’s invocation of the Srebrenica massacre showed he has no intention of calming the rhetoric being directed at the Dutch,
“The Netherlands and the Dutch, we know them from the Srebrenica massacre. We know how much their morality, their character is broken from the 8,000 Bosnians that were massacred,” Mr Erdogan said.
His remarks touch a raw nerve in the Netherlands, despite a UN tribunal prosecuting Bosnian Serbs for the actual killings.
Mr Erdogan also caused shock and outrage after likening the Dutch to Nazis. The Netherlands was invaded by Nazi Germany in 1940 and occupied right up until the final days of World War Two in Europe, in May 1945. Rotterdam was devastated by German bombing during the invasion.
He has called the Netherlands to a “banana republic”. The country, which has the sixth largest economy in the EU, is the biggest source of foreign investment in Turkey.
How is this affecting the Dutch election?
The latest development comes just a day before voters in the Netherlands go to the polls for a general election dominated by concerns about immigration and Islamic radicalism.
The anti-Islam Freedom Party of Geert Wilders has long been seen as benefiting from the anti-establishment sentiment which fuelled the victories of Brexit campaigners in the UK and Donald Trump in the US last year.
However, Mr Rutte’s handling of the Turkish rallies may benefit his centre-right People’s Party for Freedom and Democracy (VVD), which governs in coalition with the Labour Party.
The Peilingwijzer poll of opinion polls suggests the VVD will win 17% of the vote to 14% for the Freedom Party.
Party leaders are due to hold a final debate on Tuesday evening.
Could there be wider repercussions?
Mr Erdogan has warned of other, unspecified measures Turkey might take against the Netherlands.
Relations between the EU and Turkey, a predominantly Muslim country regarded as crucial to tackling Europe’s migrant crisis, have long been strained.
Turkish officials have suggested reconsidering part of the deal with the EU to stem the flow of undocumented migrants.
The number of migrants reaching Greece by sea dropped sharply after the deal was reached in March of last year.
