All American and international advisers today deserted Afghan government buildings after two senior US officers were murdered in their office at the interior ministry in Kabul.
The unnamed colonel and major were shot in the head at the high security compound at the heart of the Afghan government,
Reports suggest they were shot in the ministry's command and control centre. The compound would have been crawling with Afghan police.
The killing of the two high ranking US military advisers- is thought to be retaliation for American troops burning copies of the Koran - as bitter protests over the controversial actions enter their fifth day.
NATO earlier issued a statement confirming the two deaths.
It said.'Initial reports indicate an individual turned his weapon against International Security Assistance Force (ISAF) service members in Kabul City today [Saturday], killing two servicemembers.'
NATO spokesman Lt. Col Jimmie Cummings said 'initial reports say it was not a Western shooter.' He declined to provide further information.
NATO forces have advisers embedded in many Afghan ministries, both as trainers and to help manage the transition to Afghan control and foreign forces prepare to withdraw by the end of 2014.
The Afghan Interior Ministry oversees all of the country's police, so has numerous NATO advisers.
