Since the devastating attacks of 11 September 2001 on the World Trade Center, international cooperation to combat terrorism has developed significantly both at the global and regional levels within bodies such as the United Nations (UN) and the European Union (EU) respectively (Cortright and Lopez, 2007; Spence, 2007; Weiss and Boulden, 2004). One of the most important dimensions of counter-terrorism is combating terrorist financing (CTF) (Acharya, 2009; Biersteker, Eckert and Romaniuk, 2008). While it has often been observed that the conduct of terrorist attacks does not necessarily require large amounts of money, it is generally acknowledged that the preparation of attacks and the other activities of terrorist groups-such as recruitment, training, propaganda, and the promotion of terrorist causesnecessitate higher levels of funding (Acharya, 2009; Clunan, 2007; Richard, 2005, 5-6). Preventing would-be terrorists from accessing funds is therefore a way to disrupt their activities and prevent future attacks (Gardner, 2007, 157). Focusing on the money trail left by terrorists also allows investigators to gather evidence against terrorists and to generate intelligence concerning terrorist groups (Bures, 2010, 419). Terrorism can be funded legally or illegally (Acharya, 2009). Lawful or legitimate funds include money raised by charities, donations and the proceeds of other forms of fund-raising, whereas illegal funds refer to proceeds of criminal activities such as money-laundering, drug trafficking, and illegal arms trade. Such proceedings would be frozen or seized even if they were not destined to finance terrorism, in contrast to legal funds that can only be frozen or seized if it is intended that they should finance terrorism (Bantekas, 2003, 316). 1 In addition, terrorism can be funded by states or private actors. As there has been a significant decrease in the number of states financing terrorism over the last few years, the role of private actors in the financing of
