Saudi authorities in Jeddah and Asir region have foiled separate attempts to smuggle narcotics into the kingdom, the Saudi Press Agency (SPA) said on Sunday.
In Asir, Border Guards seized 300 kilograms of hashish from a boat as it entered Saudi territorial waters. 
Commodore Saher bin Mohammed Al-Harbi, spokesman of the Border Guards, was quoted as saying two Yemeni nationals on board the boat were arrested.
In Jeddah, Customs officers seized 1,751,000 Captagon pills at the Jeddah Islamic Port.
Saad Buqami, speaking in behalf of the general manager of Customs Jeddah Islamic Port, said the pills were concealed in a shipment of "electric cable interconnection.” 
Gangs have been relentless in their attempts to smuggle banned drugs into the kingdom despite the harsh penalty and intensified campaign against the menace.
On Friday, two women were caught trying to smuggle a total of 1,446 grams of cocaine into the kingdom through the King Abdulaziz International Airport in Jeddah.
Hamoud Al-Filai, customs director general at KAIA, said the banned drugs were found hidden in the bowels of the suspects, who were in separate flights. The drug couriers were made to swallow the finely wrapped cocaine capsules.
