The Saudi Arabian authorities arrested 22 people and seized more than 400 kilogrammes of drugs in the past week, a spokesman said on Monday.
“The guards in the southern border (Jizan, Najran and Asir) foiled an attempt to smuggle hashish and heroin into the country,” the Saudi Press Agency quoted the spokesman as saying.
“The drugs were coming from Yemeni territory. Twenty-two people were arrested.”
Of the 22 suspects, 11 were Ethiopians, 10 were Yemenis and one was a Saudi citizen.
The report said that they were caught with 356 kilogrammes of hashish and 42 kilogrammes of heroin.
