A man just drove a huge truck through a crowd of people celebrating Bastille Day in the French city of Nice, killing at least 77 in what President Obama and French officials have characterized as a devastating terrorist attack. Rihanna was in Nice at the time of the attack preparing for a concert scheduled for Friday, but ABC News reports that her show has been cancelled in the wake of this tragedy. Christian Estrosi, the president of the region that includes Nice, has announced that the city’s jazz festival, which was supposed to open on Saturday, has also been cancelled.

Dès demain les drapeaux de la ville seront en berne. Après l'annulation du concert de Rihanna, le festival du jazz est annulé.
