Two days after the death of the 10-year-old identified only as Fayed, an 18-year-old was killed during a drug deal.

The teen is believed to be the initial target on the evening that Fayed died, said Marseille prosecutor Nicolas Bessone.

Eight men aged between 18 and 30 have been remanded in custody while a 17-year-old has been placed under judicial supervision, he said.

“The young Fayed and his family had nothing to do with drug trafficking and are obviously collateral victims, perhaps a mistake in targeting due to the make of the car they were in,” Bessone said.

The boy was killed late in the evening of Aug 21 in a gritty Nimes neighbourhood when his uncle’s car came under fire in a turf war between drug gangs.

The investigation is also turning to the nearby Mediterranean city of Marseille, with evidence suggesting the drug dealing hotspot in Nimes is backed by the “DZ Mafia”, the main gang operating in Marseille, the prosecutor said.
