In a speech given to supporters in the western Turkish city of Sakarya, President Recep Tayyip Erdogan invoked the medieval religious wars between Christian Europe and the Islamic Middle East in the context of present-day escalating tensions between the European Union and Turkey.

"My dear brothers, a battle has started between the cross and the half moon. There can be no other explanation," Erdogan said on Thursday.

The Turkish president also stated the European Court of Justice's (ECJ) Tuesday ruling, which permits companies to ban the Islamic headscarf as part of policies barring religious symbols in the workplace, was the start of a "crusade" by Europe.

EU-Turkish spat simmers on A battle between the cross and the half moon? President Recep Tayyip Erdogan has repeatedly accused Dutch and German politicians of acting like "Nazis" and claiming the "spirit of fascism" is rampant in Europe. He later invoked medieval religious wars in the context of escalating tensions between the EU and Turkey. "My dear brothers, a battle has started between the cross and the half moon. There can be no other explanation," Erdogan said.

EU-Turkish spat simmers on Never let a crisis got to waste Turkish Foreign Minister Mevlut Cavusoglu, meanwhile, was not to be outdown by his boss. Speaking on Thursday, Cavusoglu said Europe was losing its unity. "Religious wars will soon begin in Europe... If things continue as they are, then it will be so." "You will learn how to behave towards us. If you do not learn, we will teach you."

EU-Turkish spat simmers on Indefatigable, as ever German Chancellor Angela Merkel welcomed the election victory for the center-right prime minister Mark Rutte in divisive Dutch elections. "I was very happy that a high turnout led to a very pro-European result, a clear signal," she said. "I don't intend to participate in this race to trade provocations." Referring to Erdogan's attacks, she added: "The insults need to stop."

EU-Turkish spat simmers on Ratchet down, not up Meanwhile, Germany's Interior Minister Thomas de Maiziere said Ankara was playing the victim with its attacks on its NATO allies to galvanize support ahead of its referendum in April. Turkish politicians had "no business" campaigning in Germany, he said. France and Germany plan to establish a European center to counter extremist propaganda and deradicalize young people, he also revealed this week.

EU-Turkish spat simmers on Rutte stems the populist tide After a week of heightened tensions between Turkey and the Netherlands, Dutch Prime Minister Mark Rutte emerged victorious in a bruising battle with Geert Wilders. The populist's invective against all things Muslim and anything from the EU failed to earn him the breakthrough that many had come to count on as a given.

EU-Turkish spat simmers on Hollande happy over Holland French President Francois Hollande congratulated Rutte for his election success and his "victory against extremism." He said that "the values of openness, respect for others, and a faith in Europe's future are the only true response to the nationalist impulses and isolationism that are shaking the world." In a joint statement with Angela Merkel, he denounced Erdogan's remarks as "unacceptable."

EU-Turkish spat simmers on Paris: next stop on the populist express After boosts in Britain and the United States over the past year and Wednesday's setback in the Netherlands, populism now heads to France for its next test of political viability. Now it is for Marine Le Pen of the National Front to carry the torch in presidential elections starting next month.

EU-Turkish spat simmers on Right message, wrong ring tone? Meanwhile, Germany's far-right kept on message. "I can not hide the fact that we wanted Wilders to have had a better result," the leader of the populist Alternative for Germany (AfD) Frauke Petry said. "Wilders addressed the right issues in the election campaign, but he might not always have had the right tone. Citizens want a clear message, but they are afraid of a hard tone," Petry said.

EU-Turkish spat simmers on Moscow fans the flames Konstantin Kosachev, chair of the Foreign Affairs Committee in the Russian parliament, wrote that Europe had been "weakened" by the elections in the Netherlands. "French Presidential candidate Emmanuel Macron and Merkel may breathe for the time being after the victory of Rutte, but the fear among the established European elites facing the challenges of the 21st century remains palpable," he wrote.



Erdogan has recently upped his antagonistic rhetoric towards Europe after Germany and the Netherlands both canceled campaign appearances by Turkish politicians. The events were intended to drum up support for an April 16 referendum that, if approved, would vastly expand Erdogan's presidential powers.

Erdogan has repeatedly compared the behavior of German and Dutch politicians to that of "Nazis" and accused Europe of hosting the "spirit of fascism."

"Europe is swiftly rolling back to the days before World War II," he said in his speech in Sakarya.

Post-election attacks on the Netherlands

Erdogan and Turkish Foreign Minister Mevlut Cavusoglu also took aim at the Netherlands on Thursday despite the previous day's election result, in which Dutch voters rejected right-wing populist Geert Wilders and his Islamophobic and anti-immigration platform.

"Hey Rutte! You may have emerged as the number one party in the election but you must know that you have lost Turkey as your friend," Erdogan said in his televised speech.

Many analysts believe Rutte's hardline approach to prohibiting Turkish politicians from campaigning in the Netherlands helped him gain the support of undecided voters who buoyed him to victory over Wilders.

Despite Turkey's previous criticism of the virulently anti-Islam Wilders, Cavusoglu told a Turkish broadcaster on Thursday that there was "no difference" between the liberal Rutte and "fascist" Wilders.

The antagonistic rhetoric and authoritarian power expansions, as well as Ankara's threats to suspend the 2016 migration agreement with the EU, has thrown the EU neighbor's long-standing bid for entry into the bloc into question.

However, Cavusoglu later said in a different interview that "no reason" existed for Turkey to "move away from Europe."

Erdogan and Merkel have butted heads over Turkish campaign appearances in Germany

Merkel: 'The insults need to stop'

For her part, German Chancellor Angela Merkel denounced Erdogan's latest round of accusations. The Turkish president accused Merkel this week of supporting terrorists in the anti-Erdogan Kurdistan Workers' Party (PKK).

"I don't intend to participate in this race to trade provocations," she told the German regional newspaper "Saarbrücker Zeitung."

"The insults need to stop," she added in comments printed in the paper's Friday edition, referencing Turkey's Nazi comparisons aimed at the Netherlands.

Merkel stated that Turkish political leaders are permitted to appear in the country under certain conditions: they must disclose who will appear and for what goal, and the foreign politicians must abide by Germany's laws and constitutional principles.

"We do not give anyone a carte blanche for the future," she added.

The chancellor's comments came the same day the city of Hannover scrapped a Friday rally organized by the Union of European Turkish Democrats (UETD) at which a senior Erdogan government official was set to appear.

The last-minute cancellation indicates tempers could get hotter and the Turkish-German relationship perhaps even cooler.
