The Director General of the Swedish Security Service raised the nation’s terrorist threat level to its second-highest, according to a Thursday press release from the Security Service.

The Security Service said the decision to raise the terrorist threat level was “not linked to any specific event, but is to be considered in a strategic, long-term perspective.”

Despite the Security Service’s remark, Sweden’s National Security Advisor Henrik Landerholm made a statement that in the wake of Quran burnings “a number of things have happened that, together, indicate a heightened threat to Swedish interests abroad.” Landerholm noted the storming of Sweden’s Embassy in Baghdad, Iraq and an attempted attack on Sweden’s Embassy in Beirut, Lebanon contributed to the view of a worsened security situation.

Britain’s foreign ministry updated their travel advice for Sweden on Sunday, stating “terrorists are very likely to try and carry out attacks in Sweden” and “authorities in Sweden have successfully disrupted a number of planned attacks and made a number of arrests.” The US Embassy in Sweden released a security alert in February of possible terrorist attacks as retaliation for Quran burning in Europe.

The Swedish Security Service uses a five-level terrorist threat level scale. Sweden has been at a 3/5 (elevated threat) since fall 2010. The last time Sweden was at the current level was in November 2015, three days after terrorist attacks in Paris.
