NATO, meanwhile, has announced it killed sixteen people this week in a rare drone attack inside Afghanistan. NATO says the victims were all militants based in southern Afghanistan. In an interview with the Wall Street Journal, a “senior US military official” said he expects an escalation of drone attacks inside Afghanistan in the coming months. The top US oversight investigator in Afghanistan has revealed only one-fourth of current corruption probes involve strictly Afghan suspects. The investigator, Raymond DiNunzio, says the remaining three-quarters involve at least one Western suspect.
