Twelve people were wounded when a grenade was thrown into a bar in the city of Grenoble in south-eastern France, officials said on Wednesday.

The attacker entered the bar, which was packed with customers, and threw a grenade before fleeing without saying a word, said prosecutor Francois Touret-de-Courcy. Investigators had not yet identified a motive but did not believe it was a terrorist attack

Magistrate Christophe Barret said the attacker appeared to be carrying a Kalashnikov-type assault rifle but did not use it.

The incident took place in the Olympic Village neighbourhood, built when the city hosted the 1968 Winter Olympics, said Touret-de-Courcy.

The wounded included two people in critical condition, said Touret-de-Courcy, but that figure was later raised to six by local Isère official Catherine Séguin.

“I condemn in the strongest possible terms this criminal act of extraordinary violence,” the local mayor, Eric Piolle, wrote on X, thanking the emergency services for their work.

Police confirmed the explosion had been caused by a thrown grenade.
