Joggers, cyclists and sun-seekers are back on Nice's famed Riviera coast, a further sign of normal life returning on the Promenade des Anglais where dozens were killed in last week's Bastille Day truck attack.

Under a blazing sun, there were few visible reminders of the carnage on Tuesday, save for a handful of flags flying at half-staff and a number of armed soldiers patrolling the promenade.

Some of Nice's beachside restaurants were reopening for business, and the final section of the Promenade des Anglais was set to reopen to traffic following three days of official mourning.
