Lorry Killer 'Visited Scene Twice Before Attack'

The man who drove a lorry into a crowd in Nice is believed to have gone to the scene twice in his rented truck before the attack.

The news came from a judicial source as two more people were arrested over the Bastille Day atrocity which claimed at least 84 lives and left more than 200 injured.

Mohamed Bouhlel, a 31-year-old French Tunisian who had lived in the French city for a number of years, mowed down revellers who gathered on the promenade for a fireworks display on Thursday night.

Bouhlel, who was shot dead by police after the attack, is thought to have made trips to the seafront on the two days leading up to the massacre.

Around 85 victims remain in hospital and 18 of them - including one child - are in a life-threatening condition.

Of the 84 people who died, 16 remain unidentified along with one of the injured.

Meanwhile, a man and a woman were held in Nice on Sunday morning.

Their arrests follow the detention of five other people since the tragedy, including Bouhlel's estranged wife. She has now been released from custody.

Authorities are trying to determine if he acted alone but the country's prime minister has said he had been radicalised quickly.

Several people, among hundreds who have been questioned, said Bouhlel showed signs of being religious, according to the judicial source.

But some of his friends and relatives have claimed he smoked, drank and never visited mosques.

Jihadist group Islamic State has said the lorry driver was one of their "soldiers".

Officials have yet to produce evidence that Bouhlel had any links to IS.

However, PM Manuel Valls said there was no doubt about the Tunisian's motives.

Speaking in an interview with Sunday newspaper Le Journal du Dimanche, Mr Valls said: "The investigation will establish the facts, but we know now that the killer was radicalised very quickly.

The claim on Saturday morning by Islamic State and the fast radicalisation of the killer confirms the Islamist nature of this attack."

He added: "Daesh (IS) gives unstable individuals an ideological kit that allows them to make sense of their acts... this is probably what happened in Nice's case."
