Brigadier General Mohammed Asid Jabarkhel tells Der Spiegel "Of course I know what's going on here." He is referring to the huge amounts of money regularly being secreted out of Afghanistan by plane in boxes and suitcases. According to some estimates, since 2007, at least $3 billion (€2.4 billion) in cash has left the country in this way.
The preferred destination for these funds is Dubai, the tax haven in the Persian Gulf. And, given the fact that Afghanistan's total GDP amounts to the equivalent of $13.5 billion, there is no way that the funds involved in this exodus are merely the proceeds of legal business transactions.
