Sweden’s national security service raised its terrorist alert to the second-highest level on August 17 and warned that the threat of attack could persist for a long time after burnings and other acts against the Koran outraged Muslims, Ednews informs referring to Reuters.
Denmark and Sweden have tightened border controls as authorities in both countries fear revenge attacks after anti-Islam activists burned and damaged several copies of the Muslim holy book in recent months.
Sweden's SAPO security service raised the warning level to 4 from 3 on a scale that runs from 1 to 5, reflecting a "high threat".
"Sweden has gone from being considered a legitimate target for terrorist attacks to being considered a prioritized target," head of SAPO Charlotte von Essen told a news conference.
She also said the attack threat posed by "violent Islamist actors" has increased in the past year.
