MSAKEN, Tunisia—The uncle of the truck driver who killed 84 people on the French Riviera says his nephew was indoctrinated about two weeks ago by an Algerian member of the Islamic State in Iraq and Syria in Nice, as anti-terrorism authorities question potential accomplices in the devastating attack.
France held a countrywide moment of silence Monday to remember the victims, but the national mourning was punctured by anger and political division. Crowds massed on the Riviera seafront booed the visiting prime minister, whose Socialist government is coming under increasing criticism from the public and the conservative opposition for failing to prevent the Bastille Day carnage.
ISIS claimed responsibility for last week’s attack, though Interior Minister Bernard Cazeneuve said Monday that investigators have found no sign yet that attacker Mohamed Lahouaiyej Bouhlel had links to a particular network.
