French Prime Minister Manuel Valls proclaimed that Lahouaiej-Bouhlel was "probably linked to radical Islam in one way or another", and put the attack in the context of a "war" against terrorism and "extremist" Islam both outside and within France. This allegation was initially cautioned by the French Interior Minister Bernard Cazeneuve, who said "We have an individual who was not known to intelligence services for activities linked to radical Islam" and who could not confirm Lahouaiej-Bouhlel's motives were linked to radical jihadism. The next day, Cazeneuve said "It seems that he [Lahouaiej-Bouhlel] radicalized himself very quickly," early investigations had found.
