In recent decades, combating money laundering and terrorist financing have attracted a growing interest. In fact, they constitute one of the most serious international crimes because of their negative effects on the economic, social and political levels and their strong correlation with other horrible crimes, such as drug trafficking, corruption, human trafficking, migrant smuggling and other crimes, which are considered predicate crimes of money laundering. In addition, such crimes are usually committed for providing the financing necessary for performing terrorist acts. International conventions affirmed the necessity of combating money laundering, including the United Nations Convention against Illicit Traffic in Narcotic Drugs and Psychotropic Substances, the United Nations Convention against Transnational Organized Crime and the United Nations Convention against Corruption.
