The threat to Sweden of a terrorist attack has recently changed, the security service Säpo said in a statement Friday. Responding to the situation, the security service has raised the terror alert from "low" to "elevated".

Sweden has never before had a terror threat on this level.

The security service said that "the assessment is based on intelligence indicating a shift in activities among certain groups in Sweden, judged to be targeted at Sweden."

The Director General of Säpo explained that the threat to Sweden "is not currently assessed to be imminent". But he refused to comment on who might be behind the threat – or if any specific part of Sweden is being threatened.

The decision to raise the threat level by one step is based on an assessment produced by the National Centre for Terrorist Threat Assessment, NCT.

“According to their analysis, there is currently an elevated threat of a terrorist attack against Sweden. The NCT have previously assessed the terrorist threat to Sweden as low, but now make an adjustment”, the security service said.

The agency also pointed out that "compared to the situation in several other European countries, the threat level to Sweden is still low."

The decision was made in the middle of September, but announced today Friday.

The threat level scale:
1. No threat
2. Low threat
3. Elevated threat
4. High threat
5. Very high threat
