BEIRUT (Reuters) – About 2,000 Syrian troops have pulled out of eastern Lebanon over the past week, a senior Lebanese security source said Monday, bringing Syria a step closer to ending its 29-year military domination of Lebanon. The source said small units in the eastern Bekaa Valley were going home, leaving behind a division of the Syrian army as well as scores of intelligence agents. A Syrian-Lebanese military committee is due to meet next week to set a timeline for withdrawing the 8,000 remaining forces. U.N. Secretary-General Kofi Annan has said he expects Syria to complete the pull out before general elections due in May.
