JOHANNESBURG - Islamic State has claimed responsibility for the Thursday night attack in the Riviera city of Nice that left at least 84 dead.

A truck driven by a 31-year old Tunisian driver zigzagged along the city's seafront Promenade des Anglais as a fireworks display marking the French national day ended. It careered into families and friends listening to an orchestra or strolling above the Mediterranean beach towards the century-old grand Hotel Negresco.

At least 10 children were among the dead. Of the scores of injured, 25 were on life support, authorities said on Friday.

The driver, Mohamed Lahouaiej Bouhlel, was shot dead by officers at the scene. He was known to police for petty crimes but was not on a watch list of suspected militants.

Meanwhile, French police arrested three people in Nice early on Saturday in connection with the probe into the Bastille Day attack, police sources said.

The arrests concerned the attacker's "close entourage", the sources said, and were made in two different areas of Nice. A Reuters reporter saw about 40 elite police raid a small apartment at Rue Miollis, north of the central station, where one individual was arrested.
