A relative of the 31-year-old Tunisian man who committed last week's deadly attack in Nice, France, believes he may have been radicalized just weeks before the Bastille Day tragedy.

FOX's Jessica Golloher has more from the region:

The 31-year-old Tunisian man who drove his truck through a crowd of Bastille Day revelers here in Nice had planned his attack prior to the celebrations.

The Paris prosecutor saying the attacker had recently developed an interest in radical Islam, but there are no elements in the investigation so far suggesting an allegiance to ISIS. The attacker's uncle claims he had been radicalized two weeks ago by an Algerian here in Nice with ties to Islamic Insurgence. 

84 people were killed, 56 people remain hospitalized 25 are in critical condition.
