RIYADH — Saudi customs officers have thwarted two separate attempts to smuggle 8,763 kilograms of methamphetamine in the Kingdom, the Zakat, Tax and Customs Authority (ZATCA) said on Monday. In the first incident, 6,497kg of methamphetamine was seized from a car crossing into the Kingdom through the Al-Bathaa bordering crossing on the UAE border. The contraband was found hidden inside a roof cavity of the car. Meanwhile, 2,266kg of methamphetamine was found hidden in the luggage of a passenger arriving at King Khalid International Airport in Riyadh.
