AP Sources: US Close to OK on Arming Syrian Rebels U.S. officials say the Obama administration could decide this week to approve lethal aid for Syria's rebels. The administration will also weigh the merits of a less likely move to send in U.S. airpower to enforce a no-fly zone in Syria. Officials say White House meetings are planned over the coming days as Syrian President Bashar Assad's government forces are apparently poised for an attack on the city of Homs. Opposition leaders are warning Washington their rebellion could face devastating losses without greater support. The warnings are prompting the United States to consider drastic action. Officials say President Barack Obama is leaning closer toward signing off on sending weapons to rebel units. The officials spoke on condition of anonymity because they weren't authorized to speak publicly on the matter.
