Turkey summoned the Danish ambassador on Friday over reports that an anti-Islam activist would be allowed to burn the Quran during a series of protests in Copenhagen.

Rasmus Paludan, a far-right activist who holds both Danish and Swedish citizenship, infuriated Turkey by staging a Quran-burning protest in Sweden on Jan. 21. He told Swedish newspaper Aftonbladet that he would replicate the protest in front of the Turkish Embassy in Copenhagen every Friday until Sweden is admitted into NATO. Reports said he would first burn the Quran outside a mosque in Copenhagen, then stage the same demonstration in front of the Turkish and Russian embassies.

Denmark’s attitude is unacceptable

Turkey’s state-run Anadolu Agency said the Danish ambassador was summoned to the Turkish Foreign Ministry where Turkish officials “strongly condemned the permission given to this provocative act which clearly constitutes a hate crime.”

The ambassador was told that “Denmark’s attitude is unacceptable” and that Turkey expected that the permission be revoked, according to Anadolu.

Paludan’s action last week caused a fury in Turkey, which criticized Swedish authorities for allowing the demonstration to take place outside the Turkish Embassy. Turkey’s president cast serious doubt on NATO’s expansion, warning Sweden not to expect support for its membership bid in the military alliance.

Turkey also indefinitely postponed a key meeting in Brussels that would have discussed Sweden and Finland’s NATO membership, saying such a meeting would have been “meaningless.”

His party received just 156 votes nationwide

Sweden and Finland abandoned their long-standing policies of military nonalignment and applied for NATO membership after Russian forces launched a full-scale invasion of Ukraine on Feb. 24. NATO-member Turkey, which is pressing the two countries to crack down on Kurdish militants and other groups it considers terrorists, hasn’t yet endorsed their accession, which requires unanimous approval from all existing alliance members.

A lawyer, Paludan established far-right parties in both Sweden and Denmark that have failed to win any seats in national, regional or municipal elections. In last year’s parliamentary election in Sweden, his party received just 156 votes nationwide.

“This is Erdogan’s fault. Now that he doesn’t want to let Sweden into NATO, I have to teach him about freedom of speech until he does,” Paludan told Aftonbladet.
