In a propaganda video released by the SITE Intelligence Group Wednesday, an ISIS member describes the Barcelona perpetrators as “our brothers,” while another threatens “Spanish Christians” and promises to return the country to the “land of the Caliphate.”
Soon after the Barcelona attack, ISIS’ media wing, Amaq, issued a statement calling the attackers “soldiers of the Islamic State,” although ISIS did not explicitly claim responsibility.
Four men have been arrested since the attack — one in Alcanar and three in Ripoll. Three were Moroccan citizens and another was Spanish; the men ranged in age from 21 to 34. None were on authorities’ radar for potential terrorism links.
