Why has ISIS not yet claimed the New Orleans vehicle attack?

CNN — It is the deadliest attack by an ISIS supporter on the West in several years. But still, almost a week later, the group also known as Islamic State has yet to issue its trademark claim of responsibility for the horrific New Year’s violence in New Orleans. It seems an unmissable opportunity to claim a direct hit on the ‘biggest Satan.’” Peter Neumann, professor of security studies at King’s College London, said: “It would be very unusual for ISIS not to claim this attack, given that the attacker openly declared his allegiance to the group and even put an ISIS flag on his truck.” The group’s hierarchy, traditionally based in Syria and Iraq, is perhaps reeling from persistent US airstrikes, recently bolstered by the French, both Neumann and Fitton-Brown said. However, Neumann added this possible disruption had not stopped ISIS from publishing its so-called weekly “newspaper” al-Naba, so it was curious the group could not simply publish a claim on social media about the New Orleans atrocity. He said he expected to see at least a reference to the attack in al-Naba, published Thursdays.. Another possibility is that ISIS could be waiting longer to issue the claim, at a time when it might highlight the attack in the news cycle again and gain greater attention from the incoming Trump administration, which takes office on January 20.
