Moroccan security forces seized 38.720 kilograms of cocaine at the El Guerguerat border crossing, near Dakhla, on Tuesday.
A 30-year-old Moroccan driver was arrested and is being investigated to uncover local and international connections.
Authorities received information about a potential smuggling attempt and intercepted the shipment at the southern border.
The cocaine was concealed in 37 plates, hidden inside a Morocco-registered international freight truck coming from sub-Saharan Africa.
This operation is part of Morocco’s ongoing efforts to combat international drug trafficking.
