More than 80 people died, including at least 10 children, when a man purposely drove a truck through a crowd that was celebrating Bastille Day in Nice, France on Thursday night. The driver, identified as a 31-year-old Tunisian man living in France named Mohamed Lahouaiej Bouhlel, reportedly drew a gun on police and was shot and killed by them.

French President Francois Hollande called the incident a terrorist attack though Bouhlel has not been linked to any terrorist group. BFM TV reported that the father-of-three became depressed after the breakdown of his marriage and that he had a criminal history that included domestic violence, robbery, and assault with a weapon.

Tributes from around the world poured in for the victims of the attack, the second major incident to hit France in less than a year. Last November, a series of organized terror attacks in Paris killed 130 people.

Many members of the Hip Hop community responded to the incident on social media, including Rihanna, who was in Nice when the attack happened. Her concert in the city, planned for Friday night, has been canceled.
