MASNAA BORDER POST, Lebanon – Sheltering from the searing heat in the shade of his truck, a red-faced and sweating Ali Bakri glared angrily at the endless line of cargo trucks stranded on the Lebanese-Syrian border. “We are being treated like animals. We have no food, no water to wash. How long can this go on?” the 35-year-old Jordanian trucker said Monday.Fresh fruits are turning to mush as customs officials carry out excruciatingly thorough searches, spending up to an hour with each vehicle. Previously, Syrian officials gave only cursory searches and often simply waved drivers through. Truckers now wait in line a week or more.The drivers and their cargo are a casualty of the souring relations between Lebanon and Syria since Damascus was forced to relinquish its three-decade-long military grip on Lebanon three months ago.Many Lebanese say Syria has clamped what amounts to a land and sea siege on its tiny neighbor to exact revenge following the withdrawal of thousands of troops. But the Syrians say the strict measures are aimed at catching saboteurs and militants.France, a close Lebanese ally, has criticized the Syrian border actions. U.N. envoy Terje Roed-Larsen briefed European Union foreign ministers on the dispute Monday and urged Lebanon and Syria to end the impasse.Lebanon’s only land outlet is via its shared border with Syria, through which 60 percent of Lebanese exports pass on their way to other Arab and Gulf markets, officials say. The dispute is estimated to be costing Lebanon over $300,000 a day.
