Norway on Sunday revised downwards the risk of a terrorist attack by militants coming from Syria, three days after stepping up security to face a threat it deemed "credible" and imminent. "Based upon the work carried out these last days, we can say that the threat of a terrorist attack against Norway has somewhat decreased," Norway's intelligence service (PST) chief Benedicte Bjoernland said at a press conference.
"But the situation is still serious and hasn't been clarified yet." The PST declined to reveal the reasons behind its new assessment, explaining only that it was supported by information obtained in Norway and abroad.
On Thursday, PST said it had "recently received information that a group of extremists from Syria may be planning a terrorist attack" in the country.
The threat was deemed "credible" but "non-specific". The eventual target, the timing of the attack, the identity of the militants and their location were not known, PST said.
Norway will keep tightened security measures "until further notice", police head Odd Reidar Humlegaard said on Sunday. Norway has increased border controls and armed police presence in stations and airport, recalled officers from leave and closed several public buildings to the public. The country's Jewish museums are also closed.
