United States has imposed sanctions on a network individuals and companies accused of forging money to help Iran's Revolutionary Guards. <br/><br/>Officials announced, the sanctions targeted four companies and two individuals involved in printing counterfeit Yemeni currency to benefit Iran, including Iranian national Reza Heidari and Mahmoud Seif, whose nationality was not given. <br/><br/>According to a statement yesterday, the US Treasury said both allegedly used the companies to evade European export restrictions while procuring equipment used to print fake Yemeni currency potentially worth hundreds of millions of US dollars. <br/><br/>This benefited the Revolutionary Guards' external operations arm, which has been subject to US sanctions since 2007.
