Interior Minister Laurent Nuñez said he had ordered a temporary halt to the use of grenades in the context of the secondary-school student movement, pending clarification of what happened, according to the Guardian.
The measure applies to student demonstrations, but the available information does not specify either the duration of the suspension or its exact operational scope beyond this area.
The case that preceded the announcement concerns a 15-year-old protester who lost a hand during a demonstration in Lens, in northern France, last Monday.
The connection between the injury and a police grenade has been reported by the sources, but the precise mechanism has not been established: the available reports differ on whether the hand was struck by the explosion or whether the injury occurred while the boy was handling the device.
The suspension follows complaints and allegations of disproportionate use of force and police brutality during student protests, according to accounts by BBC News, the Guardian, France 24 and Deutsche Welle.
Prime Minister Sebastien Lecornu was expected later on October 7 to address the nation, Al Jazeera, Deutsche Welle and France 24 reported.
Euronews also reported that more than 6,500 people had been arrested since the movement began, most of them minors. The figure comes from a single source among those available.
