As night falls on remote villages in eastern Lebanon that border Syria, streets and alleyways bustle into life as a small army of pick-up trucks, mules and cars are readied for action. Loaded up with whisky, bread, metal and other goods, drivers head for the dirt roads that zig-zag through nearby hillsides and valleys to deliver loads to fellow smugglers across the border before returning with staples such as heating oil, laundry detergent and vegetables. "We work from around 9:00pm until dawn," said one 46-year-old smuggler who asked to be identified only by his initials of M.Z. "We leave home in our pick-ups, cars and even mules loaded with alcohol and other products." M.Z., who has plied the trade for decades, said smugglers from both sides have specific meeting points along the mountainous border. "Once we get to a meeting place we wait for Syrian vehicles loaded with products and we make the exchange very quickly," he added. Smuggling between Lebanon and Syria goes back to when both countries became independent in the 1940s, sharing a 170-kilometre (105-mile) long border that has never been officially delineated. "The Lebanese economy has depended on a parallel economy for ages," said Fares Ishtay, political science professor at Lebanese University. "Salaries in both countries are very low and people depend on undeclared goods to survive." He said that although hashish used to be the main contraband, other products, not considered illegal as such, have now become hot items. Weapons smuggling is a major problem but is concentrated farther north along frontier areas where the militant Shiite group Hezbollah has a presence.
