We can confirm that a small number of UK personnel were involved in an incident at the Afghan National Defense University site today in Kabul. The incident is currently under investigation and it would be inappropriate to comment on the details at this time or on issues relating to personnel from other ISAF nations.
Even in the final stages of the mission UK and ISAF personnel will never be without risk. These sorts of incidents, whilst infrequent, are tragic events and we and our ISAF and Afghan partners take them extremely seriously.
