Yesterday morning three Americans were killed by a member of the Afghan National Police who opened fire at a private hospital in Kabul. This is the second such attack on western non-combatants in Afghanistan this month. On April 4th two Associated Press journalists were also shot by an Afghan Police Soldier. Although both attacks do not meet the necessary criteria to be defined as a ‘green-on-blue’ attack (whereby a member of the Afghan National Security Forces, ANSF, kills or injury members of the coalition forces serving alongside them), their similarity is not going unnoticed. In light of the recent spike in violence against journalists and western personnel in Afghanistan it is important to consider if these attacks are an adaptation of green-on-blue attacks committed by similarly motivated offenders or if they represent a different phenomena entirely.
