Today, several cultural events across France were cancelled or postponed as a mark of respect for the 84 people killed when a gunman drove a 19-tonne truck into a crowd of revellers following Bastille Day fireworks the previous evening.
President Francois Hollande declared the incident a "terrorist" attack.
The place of the attack was a top tourist destination: the palm-lined Promenade des Anglais along the Mediterranean coast in the city which is the number two destination in France behind Paris.
Georges Panayotis, head of the MKG hotel and tourism consultancy, expressed concern about the effect the repeated attacks were having on the industry.
"This is no longer a classic terrorism situation where a couple of months is enough following an attack for economic activity to recover," said Panayotis.
The French government had just held this week its first meeting of a special government-industry committee headed by Foreign Minister Jean-Marc Ayrault to try to find ways to help the sector recover.
The number of tourists arriving on regular flights has fallen by 5.8 per cent since January, including by 11 per cent in Paris.
The number of hotel nights foreigners spend in Paris is expected to be down around 20 per cent for the prime summer season, tourism minister Matthias Fekl said in a recent interview with TourMag.
Travel sector shares took a beating today, including shares in hotel group AccorHotels and Europcar rental agency, which both fell around 4 percent in a Paris market down around 0.8 percent overall.
