At least 15 injured as gunman armed with Kalashnikov rifle throws grenade into packed bar in Grenoble before fleeing

A GRENADE was thrown into a packed bar by a man with an assault rifle in France leaving 15 injured before the gunman fled.

Six people are fighting for their lives after being wounded in the chilling attack on Wednesday night in Grenoble's Olympic Village.

Prosecutor François Touret de Coucy said: "A person came in, threw a grenade, didn't say a word, it seems, and then fled."

The assailant did not use the Kalashnikov-type assault rifle that he reportedly had when he struck shortly after 8pm local time.

Mayor of Grenoble, Eric Piolle, said he condemned the "criminal act of unprecedented violence that occurred in a business in the Olympic Village district".

The grenade's explosion shattered the windows at the front of the bar and sent glass flying across the establishment as people were drinking.

Those injured were left covered in blood in the parking lot underneath survival blankets in the cold winter night as emergency services treated them.

Prosecutor Touret de Coucy said: "There's nothing to make us think it's linked to terrorism".

He labelled the attack an "act of extreme violence" that "may be linked to a settling of scores."

The bar – Aksehir - is named after a town in the Konya Province of Turkey

All the injured were taken to the Grenoble Alpes University Hospital, BFMTV reported.

Grenoble was the host for the 1968 Winter Olympic Games.
