In a January 2002 letter to Swiss authorities, a senior Treasury Department official will claim that the Al Taqwa Bank in Switzerland had set up a highly secretive line of credit for al-Qaeda, and that it is still in use in October 2000. (Apparently its status is unknown after this time.) It states that Al Taqwa “appeared to be providing a clandestine line of credit for a close associate of bin Laden.… This bin Laden lieutenant had a line of credit with a Middle East financial institution that drew on an identical account number at Bank Al Taqwa. Unlike other accounts—even accounts of private banking customers—this account was blocked by the computer system and special privileges were required to access it.” The letter calls the circumstances surrounding the account “highly unusual” and suggests that they were created “to conceal the association of the bin Laden organization with Bank Al Taqwa.” Another document reveals that the account was originally set up for Mamdouh Mahmoud Salim, an al-Qaeda leader who was arrested in Germany in late 1998 (see September 16, 1998). It is believed that other al-Qaeda figures continued to access the account after Salim’s arrest. [US Department of the Treasury, 8/29/2002; Newsweek, 4/12/2004] The US will declare Al Taqwa Bank a terrorist financier in November 2001 (see November 7, 2001).
