French Prime Minister Manuel Valls was booed by crowds gathered in Nice on Monday (July 18) for a memorial service to honour the victims of the truck attack in the Riviera city which left 84 dead.
Valls joined thousands packing the seafront promenade, scene of the Bastille day carnage, for a minute of silence in tribute to the victims.
There were jeers as he and local politicians departed, with several in the crowd shouting: "Resign!"
French President Francois Hollande and Interior Minister Bernard Cazeneuve also held a minute of silence at a ceremony in Paris.
Confidence in the capacity of Hollande's government to combat terrorism has plummeted in the wake of the attack an opinion poll published on Monday suggested.
The poll published in Le Figaro newspaper showed 33 percent of respondents were confident in the current leadership's ability to meet the challenge, down sharply from ratings of 50 percent upwards in the wake of two major attacks last year.
