Kabul, Afghanistan (CNN) As Afghanistan mourned another deadly attack Sunday -- one that raises questions about the potential for stability in the region -- a top American general says US victory in Afghanistan is still a possibility. The blast Saturday occurred after the ambulance passed through a security checkpoint, Interior Ministry spokesman Nasrat Rahimi said. A year ago, medical facilities were off-limits; now, an ambulance can be used as a bomb. The head of the UN mission in Afghanistan said the attack was "nothing short of an atrocity" that targeted a civilian area. Hundreds more US troops are en route to Afghanistan to begin a much riskier mission: training Afghan troops outside the wire.
