Guardian Films investigation into what happened to $23 Billion in Iraqi AID

'Iraq was awash in cash. We played football with bricks of $100 bills'

At the beginning of the Iraq war, the UN entrusted $23bn of Iraqi money to the US-led coalition to redevelop the country. With the infrastructure of the country still in ruins, where has all that money gone? Callum Macrae and Ali Fadhil on one of the greatest financial scandals of all time

In a dilapidated maternity and paediatric hospital in Diwaniyah, 100 miles south of Baghdad, Zahara and Abbas, premature twins just two days old, lie desperately ill. The hospital has neither the equipment nor the drugs that could save their lives. On the other side of the world, in a federal courthouse in Virginia, US, two men - one a former CIA agent and Republican candidate for Congress, the other a former army ranger - are found guilty of fraudulently obtaining $3m (£1.7m) intended for the reconstruction of Iraq. These two events have no direct link, but they are none the less products of the same thing: a financial scandal that in terms of sheer scale must rank as one of the greatest in history.

At the start of the Iraq war, around $23bn-worth of Iraqi money was placed in the trusteeship of the US-led coalition by the UN. The money, known as the Development Fund for Iraq and consisting of the proceeds of oil sales, frozen Iraqi bank accounts and seized Iraqi assets, was to be used in a "transparent manner", specified the UN, for "purposes benefiting the people of Iraq".

For the past few months we have been working on a Guardian Films investigation into what happened to that money. What we discovered was that a great deal of it has been wasted, stolen or frittered away. For the coalition, it has been a catastrophe of its own making. For the Iraqi people, it has been a tragedy. But it is also a financial and political scandal that runs right to the heart of the nightmare that is engulfing Iraq today.
