The Turkish Foreign Minister Mevlut Cavusoglu declared on Tuesday that “effective cooperation” against terrorism with Sweden she is necessary” for the country’s accession to NATO.

Mevlut Cavusoglu’s statements were made after his meeting with his Swedish counterpart Tobias Billström on the sidelines of the two-day meeting of NATO foreign ministers in Brussels.

“We reiterated our expectations for Sweden’s NATO membership to Foreign Minister Tobias Billström,” Cavusoglu said in a tweet. “Effective cooperation against terrorism is essential.”

The president of the USA Joe Biden and NATO are calling on Ankara to agree to Sweden’s accession to the North Atlantic Alliance.

Meanwhile, an order to annul a police decision banning the burning of the Koran during a demonstration court gave in Sweden. The burning of the Koran had sparked strong protests in the Muslim world and jeopardized Sweden’s accession to NATO.

The police “did not have sufficient evidence to support their decision”, the administrative appeals court ruled in a statement, finding that the threats invoked by the police to prohibit the burning of copies of the Koran in front of the Turkish and Iraqi embassies in Sweden did not were “sufficiently specific or connected to the demonstrations in question”.
