ARSAL: This Lebanese border town has become a safe haven for war-weary Syrian rebels, a way station for wounded fighters and home to hundreds of frightened Syrian refugee families. Residents of Arsal, a Sunni Muslim town of 40,000, say they have strong motives to help those trying to topple Syria's regime: they themselves were harassed and abused by it during three decades of de facto Syrian control of Lebanon. But in siding with the rebels, many of them fellow Sunnis, Arsal is also deepening rifts with its Shiite Muslim neighbors in the Bekaa Valley that runs along Lebanon's eastern border with Syria. Large areas of the scenic valley are controlled by Hezbollah, the powerful Shiite militia that is supporting and - according to the U.S. and the Syrian opposition - also fighting alongside Syrian President Bashar Assad's forces.
