Premises housing a telephone dispatcher of the Orange group were set on fire during the night of Monday to Tuesday in the Drôme, AFP learned from the operator, confirming information from Dauphiné Libéré.
According to the regional daily, the installation of the town of Gigors-et-Lozeron is located on a steep site, at an altitude of over 1,000 m.
The burned-down room is attached to a TDF relay antenna.
"The Orange teams are mobilized to restore the fixed and mobile networks in the Gigors-et-Lozeron area, following damage caused by an act of vandalism," the group wrote in a press release.
Return to normal not yet announced
The company specifies that the fire caused "great damage" to the building and the equipment of the dispatcher, also called the subscriber connection node.
