The Bastille Day truck attack in Nice has claimed another life bringing the death toll to 85.
Christian Estrosi, president of the region where the French Riviera city is located, says on Twitter that Pierre Hattermann, 56, has died.
The local Nice Matin daily said Hattermann's wife and a 13-year-old son were killed when a truck driven by a Tunisian man barreled down the famed Promenade des Anglais as tens of thousands gathered for the July 14 French national day celebration. The attack was claimed by the Islamic State group.
Hattermann, 56, a psychologist, died Thursday at Pasteur Hospital, the paper said. He lived in the Savoie region of eastern France and had been vacationing with his family in Nice.
