By Cynthia Johnston BEIRUT (Reuters) – Syria completed the first phase of its troop pullout from Lebanon on Thursday, bringing Damascus closer to meeting U.S. and Lebanese opposition demands that it quit the neighbor it has dominated for three decades. A Lebanese security source said 4,000 to 6,000 Syrian troops had returned home since the pullout plan was announced on March 5, leaving 8,000 to 10,000 in eastern Lebanon. He said all Syrian forces had pulled back to the Bekaa Valley or crossed into Syria. “There are just some logistics left. But the people went, all of them,” he added United Nations Secretary-General Kofi Annan expects Syria to fully withdraw its forces before Lebanon’s May elections, U.N. envoy Terje Roed-Larsen said after briefing Annan on his recent talks with Syrian President Bashar al-Assad.
