Border Guard patrols along Saudi Arabia's rugged mountain frontier with Yemen report mounting interceptions of hashish, weapons and other contraband. Over the past nine months, interceptions at the Najran border post alone netted four tons of hashish, as well as explosives, hand grenades, firearms and ammunition. Some 250 smugglers and 25,000 "infiltrators" were also detained at the post, and several vehicles impounded. But Border Guard officials admit that on several occassions the smugglers got away into the wilderness, with agents firing after them. At the Wadi post, to the east of Najran, border guards last month confronted six "infiltrators," killing five and capturing the survivor. Four tons of hashish were confiscated along the border just during the holy month of Ramadan, which ended with the Eid al-Fitr festival July 28—possibly because smugglers thought patrols would be slacking off. On the contrary, Saudi forces beefed up patrols.
