Indeed, it is a massive challenge for delivering humanitarian assistance. Last year alone there were 1,400 incidents of interference by the Taliban in humanitarian deliveries. That includes efforts around diverting assistance or identifying beneficiaries who weren't part of the beneficiary role and so on.
I think what that demonstrates is that the system we had in place and that we support—the international humanitarian system—is effective in monitoring and putting in place accountability mechanisms. The monitoring and reporting they do can assure us that the assistance is getting to the individuals who need it, and indeed that this can be replicated in other contexts.
