French police were on Thursday searching for an unidentified man who hurled a grenade into a bar in the southeastern city of Grenoble, wounding 12 people, reports Barron's.
The attacker, whose motive was still unclear, entered the Aksehir bar, situated in a rough neighbourhood of the city, shortly after 8:00 pm (1900 GMT) on Wednesday, prosecutors said.
"Someone came in and threw a grenade, apparently without saying a word, and ran away," prosecutor Francois Touret-de-Courcy told reporters.
Two of the wounded were still in critical condition Thursday.
"I heard a loud bang," said Agnes Lefebvre-Paquet, a witness in her 70s.
"And I said to myself that it wasn't a firecracker. I assumed it was a neighbourhood problem."
Another neighbour, dressed in a nightgown and who declined to give her name, said: "We're all shocked."
She said she had lived in the area for 30 years and it was "getting worse and worse".
Touret-de-Courcy said the man may have also carried a Kalashnikov assault rifle but if he did, he did not appear to have fired it.
