The vicious Bastille Day attack in the French city of Nice that killed at least 84 people , including 10 children, was an act of terrorism, Frances President Francois Hollande said early Friday.

Mohamed Lahouaiej Bouhlel , a 31-year-old French Tunisian, plowed a vehicle-turned-weapon into a crowd of people who were watching fireworks. He drove for more than a mile before police shot him dead, Agence-France Press reported. The truck was loaded with arms and grenades, Region President Christian Estrosi said, but some of them were fake.

Counterterrorism officials have taken over the investigation into the attack, HuffPost France reported. Interpol announced on Twitter that its sending a team to Nice to help with the identification of victims. No group has claimed responsibility.

Police sources told The Associated Press and French media they identified Bouhlel from documents they found in the vehicle. He was known for local crimes but had no known ties to terrorism, they added.

Paris Prosecutor Franois Molins said at least 202 people were injured in the attack. Fifty-two individuals were still in critical condition Friday, he said, with 25 of those on life support. At least 50 children were among those hospitalized, French officials said. An American father and his young son were among the first victims to be identified.

France will observe three national days of mourning, beginning Saturday.
