Hundreds of Afghan soldiers have been discharged or arrested as part of an investigation into their backgrounds after a surge in insider attacks against foreign troops.
The Defence Ministry did not provide any other details or specific numbers. A spokesman said many of the troops had been discharged from the military because they had suspect documents, either incomplete or forged.
Many Afghans seek to join the army or police to secure stable employment.
The spokesman added that the investigation began about six months ago and promised more details next week.
On Sunday the deputy commander of the Nato coalition also confirmed that some soldiers were suspended but did not give numbers.
