A hooded man fired from a vehicle before fleeing, said Guillaume Petitclair, first deputy mayor of the commune of Villerupt. Three injured were classified as an absolute emergency, one of them with a life-threatening prognosis, he said.
"It's three young men and a young woman, who are probably between 15 and 20 years old," he added. According to a close source, this shooting could be linked to drug trafficking, which the investigation will have to determine.
