Hundreds of soldiers have been detained or removed from the Afghan National Army in 2012 after a surge in insider attacks against foreign forces who are their supposed partners in the fight against Taliban insurgents and other militants. The Afghan officials say they are re-vetting soldiers to stem the attacks that threaten to unravel the international community's alliance with the fragile government trying to stand on its own as foreign troops withdraw.(AP Photo/Maya Alleruzzo, File)
