Islamic State Group Claims Nice Attacker as a 'Soldier,' Five Suspects in Custody

NICE, France (AP) — The Islamic State group on Saturday claimed the Tunisian man who barreled his truck into a crowd in the French resort city of Nice was a "soldier" of the group, the first claim of responsibility for an attack that has claimed 84 lives at a July 14 fireworks display.

The claim — circulated on social media by a news outlet affiliated with the group — didn't name Mohamed Lahouaiej Bouhlel, the 31-year-old Tunisian who authorities say was behind the wheel as a truck crashed into a crowd of revelers at a fireworks display on Thursday. But the statement quoting a security member of the group said the man was following calls from IS to target nationals of countries fighting it.

It's unclear whether or not Bouhlel was acting alone. The Paris prosecutor's office said Saturday that five people are in custody following the attack.

The identities of most of those brought into custody were not clear. But neighbors in the Nice neighborhood where the Bouhlel used to live told The Associated his estranged wife had been taken away by police on Friday.

The claim of responsibility came as French security chiefs met in Paris and as Nice's seaside boulevard, the famous Promenade des Anglais, is slowly coming back to life. A makeshift memorial of bouquets, candles and messages had been set up near one end of the expansive avenue.

France is observing three days of national mourning in homage to the victims — although that hasn't stopped politicians from sniping at each other over who bore responsibility for the failing to stop the attack.

In an open letter published on the Nice Matin newspaper's website, regional council President Christian Estrosi — a member of France's opposition Republicans — described the country's current leadership as "incapable." He said he had requested that the police presence be reinforced in Nice ahead of the display but was told there was no need.

France is heading into elections next year, and the deeply unpopular French President Francois Hollande is facing a tough challenge both from within his party and from the Republicans as well as the far-right National Front.
