Panetta says toughest fighting in Afghanistan yet to come
In his exclusive sit-down with Foreign Policy on Friday, Defense Secretary Leon Panetta said that some of the ``toughest'' fighting in Afghanistan is yet to come.
US Defense Secretary Leon Panetta arrived in Afghanistan on Thursday for talks with military leaders amid rising violence in the war against the Taliban and a spate of deadly incidents, including a NATO air strike said to have killed 18 villagers.
