Bono was dining with Nice's former mayor, Christian Estrosi, at La Petite Maison next to Promenade des Anglais when the terror attack occurred, according to The Mirror.
"It took around half an hour for the police to get us out," a diner told the paper. “Like everybody else, Bono had to put his hands on his head, and was told to remain calm.”
The diners were instructed to wait in the restaurant with the shutters drawn until they got the all-clear, and then police escorted them to nearby Massena square.
Bono was also in Paris during last year's Bataclan attacks, which left 130 people dead and 368 injured. The next month, he detailed lyrics for a song called "S.O.S.," which would be dedicated to the Paris tragedy: "I came down these streets of love and pride to surrender / The streets of surrender." He has previously said that we need to battle terrorism with comedy, by deploying Amy Schumer and Chris Rock.
