I think with the rise in K&R in the region we need to start developing a consultation briefing to counter this dramatic rise of incidents across Pakistan. The UN have already moved to level 3 "Relocation" on their security management system for Pakistan in Oct 08 and then to level 4 in Balochistan only recently.
So our government need to drive home the importance of the work the UN is doing in the under developed areas of Pakistan, and why we should all as people ensure we treat visitors with hospitality and care.
At a security level, perhaps a K&RE plan needs to be devised for UN and other foreign staff, this should then be provided to compliment the incountry briefing/induction when they start their work in Pakistan.
