In this Tuesday, Oct. 2, 2012 photo, a general view of Arsal, a Sunni Muslim town eastern Lebanon near the Syrian border, has become a safe haven for war-weary Syrian rebels and hundreds of refugee families. Many in Arsal support the rebels, but the town's stand is risking heightened tensions with its Shiite Muslim neighbors in an area controlled by Hezbollah, a militia that backs the Syrian regime. Deepening sectarian rifts are one of the ways in which Syria's 18-month-old conflict is destabilizing an already volatile region. (AP Photo/Bilal Hussein)
