Authorities refused to comment on a Norwegian media report that the July 24 terror alert was triggered by warnings that four Islamic State operatives were on their way to Norway via Greece to commit a major attack. Authorities reportedly said that two Norwegians answer directly to IS leader Abu Bakr al Baghdadi; one is Bastian Vasquez, of Skien, and the other is of African origin and lived in Boerum. A Norwegian man confirmed that Greek authorities stopped a Syrian man with a Norwegian passport from flying to Oslo from Parga, Greece on Aug. 10 because he could not explain why he was flying to Norway from the resort town. Security officials said that as many as 300 Norwegian oil and energy companies were hacked, in the biggest such incident yet in Norway.
