The Turkish government demanded an apology and threatened to retaliate against the Dutch government on Sunday after its expulsion of Family Minister Fatma Betul Sayan Kaya prompted a violent protest and several arrests in Rotterdam.

Speaking at Istanbul's Ataturk airport upon her return, Sayan Kaya described her expulsion across the border to Germany as "anti-democratic" and accused the Dutch authorities of suspending "freedom of movement, freedom of speech, every kind of freedom."

Sayan Kaya crossed the border into the Netherlands from Germany to hold a campaign rally in support of constitutional reform in her country that would further expand the powers of President Recep Tayyip Erdogan.

She intended to hold the campaign speech at the Turkish consulate in Rotterdam in the place of Foreign Minister Mevlut Cavusoglu, who was unable to enter the country on Saturday after Dutch authorities revoked his plane's landing rights.

The family minister was escorted back over the German border by Dutch police, prompting a violent protest in Rotterdam overnight to Sunday.

Dutch authorities used water cannon and batons to subdue the subsequent protest, while demonstrators threw rocks and plant pots at officers, Dutch news agency ANP reported, adding that several people had been arrested.

The diplomatic row between Turkey and the Netherlands escalated on Saturday when officials in Ankara threatened to impose sanctions on the country should they be denied the right to shore up support for their reform effort.

At an event in Istanbul on Sunday, Erdogan said that the Netherlands would "pay a price" for its behaviour. Later in the day at a campaign event in eastern Turkey, he called on the international community to impose sanctions on the Netherlands, state-run news agency Anadolu reported.

Also on Sunday, Prime Minister Binali Yildirim said that Turkey's response to the expulsion would be "most severe."

Turkish Finance Minister Naci Agbal told Anadolu that the Netherlands' "anti-democratic" and "fascistic" behaviour showed that Europe was in the process of re-establishing National Socialism.

Speaking in France on Sunday ahead of a planned rally, Cavusoglu threatened to take "wide-ranging steps" against the Netherlands unless the country apologized for its behaviour, Anadolu reported.

His French counterpart, Jean Marc Ayrault, called for a "cooling down" in the row between Turkey and European countries, adding that Turkish authorities should "avoid excesses and provocations."

Thorbjorn Jagland, head of the Council of Europe, called for "constructive dialogue" between Turkey and European nations, saying that "the situation is now damaging to diplomacy and democracy - we cannot allow it to escalate any further."

Denmark also entered the fray on Sunday, with Prime Minister Lars Lokke saying that after "Turkey's latest attack against Holland" he had asked Yildirim to postpone a meeting scheduled for next week.

Also on Sunday, a protester entered the Dutch consulate premises in Istanbul and replaced the country's flag with the Turkish flag, the DHA news agency reported.

The agency showed a video of the man shouting "Allahu akbar" [God is greatest] before he left the scene. The Dutch flag has since been returned to its original place, the report said.
