A US soldier enters biometric data obtained from an Afghan man during a night raid Feb. 21 in Yahya Khel, Paktika Province. General David Petraeus has increased the use of such raids since he took over running the Afghan war last year, despite strong opposition from by President Hamid Karzai. Petraeus says the pressure on suspected insurgents and their networks has brought a new dynamic to a near-decade-old war. Critics argue it is fueling violence because poor intelligence means dozens of innocent people are killed or detained. Although more than 80 percent of recent raids ended without a shot being fired, violence escalates fast when it does break out, with 600 people killed on operations in the three-month period.
