The incident occurred shortly after 8:00 p.m. (1900 GMT) at the bar in the Olympic Village neighborhood, built when the city hosted the 1968 Winter Olympics.
“I condemn in the strongest possible terms the criminal act of unprecedented violence that took place in a shop in the Olympic Village district, which caused more than 10 injuries, several of them serious,” Grenoble Mayor Eric Piolle said late on Wednesday. “I thank the rescue and security forces for their rapid intervention.”Isere Prefect Catherine Seguin said some of those wounded in the city in southeastern France were in serious condition, newspaper Le Dauphine Libere reported.
“Someone came in and threw a grenade, apparently without saying a word, and ran away,” Deputy Prosecutor François Touret-de-Courcy told journalists at the scene, where emergency workers had cordoned off the area.
