Its intelligence services Sweden they announced the arrest today 5 suspects for planning”terrorist attack” in Sweden to retaliation for combustion copy of Koran by an extremist, something that has already had serious international repercussions.

The arrests coincide with a decision by the Swedish judiciary to overturn bans on demonstrations involving the burning of Islam’s holy book, which has sparked strong protests in the Muslim world and put Sweden’s NATO membership in jeopardy.

The anti-terrorist operation took place this morning in three different towns in central Sweden, Eskilstuna, Linsopin and Strenes, the Swedish internal intelligence service announced.

The suspects “are believed to have had international connections to violent Islamist extremism,” Säpo said, noting that it “does not believe an attack was imminent.”

Swedish anti-Islamic extremist Rasmus Paludan’s burning of a copy of the Koran in front of the Turkish embassy in Stockholm in early January embarrassed the Swedish government.

Stockholm found itself caught between the right of citizens to demonstrate in Sweden and the feelings of the Muslim world and especially Turkey.

After the permission granted in early January to Rasmus Paludan, the police chose to ban further demonstrations involving the burning of copies of the Koran, mainly citing security threats.

These bans were challenged before the kingdom’s justice system, arguing that they violated citizens’ constitutional freedom to demonstrate.

Police “did not have sufficient evidence to support their decision” to ban two demonstrations in which copies of the Koran were to be burned in front of the Turkish and Iraqi embassies, an administrative appeals court ruled today.

The judge tasked with examining the issue found that the threats invoked by the police to ban the burning of copies of the Koran were “not sufficiently specific nor linked to the protests in question,” the court said in a statement.

Burning copies of the Koran is one of the reasons why Turkey decided to approve Finland’s accession to NATO, but not Sweden.

Finland will officially join the alliance today with a ceremony in Brussels.

Sweden’s accession, however, still needs to be ratified by Turkey and Hungary. Despite these obstacles, the Nordic country still hopes to join NATO before the organization’s upcoming summit in Vilnius in July.
