Cutting off the cash.
In the wake of the 11 September attacks on New York and Washington bombs may have fallen on Afghanistan, but the world is also focused on the finances of terror.
The UK government has announced the creation of a special unit to be run by the National Criminal Intelligence Service that will include, at its heart, forensic accountants. Clearly authorities want to block the funds of terrorists, but as important, they want to be able to follow the money trail that could lead to the arrest of terrorists.
Internationally the Paris-based Financial Action Task Force has also taken up the fight against terrorism money. Next week it will stage an emergency meeting in Washington in a bid to forge a strategy.
