Soldiers of Pakistan army take positions in troubled area of Shangla in northwest Pakistan on Monday, Feb. 25, 2008. The militants that grabbed control of Pakistan's Swat Valley last fall have fled or melted away into the villages they came from. Now, as spring thaws the snow where troops have dug in through winter, the army says it has retaken a region that had slipped alarmingly from state control. (AP Photo/Matthew Pennington)
