AFGHANISTANICA has a great compilation post looking at Afghanistan’s Security Deterioration in Visual and Quantitative Form.
The post makes clear that the UNDSS report is very focused on the security of humanitarian aid worker:
'The report makes it obvious that the “Anti-Government Elements” aren’t giving aid workers any special treatment. Incidents in 2007 up to early August:
Aid convoys attacked/ambushed/looted: 41.
Aid facilities attacked looted: 29.
Aid workers abducted: 69 (44 Afghans, 25 international).
Later killed by captors: 7 (5 Afghans, 2 foreigners).
Total aid workers killed: 41 (34 Afghans, 7 international).
These numbers are of course much less than deaths suffered by Afghan civilians, police and military and less than the losses by foreign troops. But these NGO workers are desperately needed in Afghanistan, and many of them need to be out in the field to be effective.'
