There have been eight new arrests connected to the Bastille Day attack in Nice, France, according to a prosecutors’ office. The suspects are said to be French and Tunisian, and were linked by investigators to attacker Mohamed Lahouiej Bouhlel, who killed 86 people who were watching a holiday fireworks display. The attack—on July 14—also injured more than 400 people. The Islamic State terror group eventually claimed responsibility. The new arrests reportedly came Monday in the Nice area.
