Earlier, France called up 12,000 police reservists to boost security in the wake of the killings, BBC reports on Sunday (July 17).
It brings to six the number of people still being held over the attack.
The driver was shot dead by police when his vehicle's path along the seafront Promenade des Anglais was eventually halted.
A source close to the investigation told French news agency AFP that the killer had visited the area on the previous two days to prepare for the attack.
