Nice terror attack: Truck driver who killed 84 named as 'loner' French-Tunisian criminal who 'became depressed' when wife left him as police question estranged spouse
At least 84 people have been killed, including more than 10 children, after a lorry slammed through a crowd celebrating Bastille Day in the southern French city of Nice.
The driver ploughed on for 2km (1.2 miles) on the Promenade des Anglais at about 23:00 local time on Thursday, before being shot dead by police.
Witnesses say the lorry swerved in an apparent attempt to hit more people.
Guns and a grenade found inside the lorry were reported to be fakes.
President Francois Hollande, who is in Nice, said the attack was of "an undeniable terrorist nature".
He said the battle against terrorism would be long as France faced "an enemy who will continue to hit countries who see liberty as their essential value".
A state of emergency, in place since November's Paris attacks carried out by militants from the so-called Islamic State group, in which 130 people died, has been extended by three months.
