Drug-smuggling "drone submarines" seized for the first time in Spain

Spanish police said Monday they had seized three underwater drones capable of transporting large quantities of drugs from Morocco to Spain and broken up a gang suspected of manufacturing them.

Officers seized three so-called "drone submarines" which were under construction and arrested eight people in Spain, a police statement said.

"The three -- two of which were being built and one which was practically completed -- were to be delivered to French drug traffickers for transporting large quantities of cocaine," it said.
