The FBI misses a chance to learn about Zacarias Moussaoui after a raid in Dublin, Ireland. On December 14, 1999, Ahmed Ressam was arrested trying to smuggle explosives into the US (see December 14, 1999). On December 21, Irish police arrest Hamid Aich and several other North African immigrants living in Dublin. [New York Times, 1/22/2000] During the arrests, police seize a large amount of documents relating to citizenship applications, identities, credit cards, and airplane tickets. A diagram of an electrical switch that could be used for a bomb is found that is identical to a diagram found in Ressam’s apartment in Vancouver, Canada. [Irish Times, 7/31/2002] The suspects are released about a day later, but, “Within days, authorities in Ireland and the United States began to realize that they might have missed a chance to learn more about a terrorist network.” [New York Times, 1/22/2000] It is discovered that Aich lived with Ressam in Montreal, and then later lived with him in Vancouver. Investigators conclude there has been an al-Qaeda cell in Dublin since the early 1990s, when the charity Mercy International opened an office there (this charity has several known al-Qaeda connections by this time (see 1988-Spring 1995 and Late 1996-August 20, 1998) and also an alleged CIA connection (see 1989 and After)). The cell is mainly involved in providing travel and identity documents for other cells committing violent acts. Investigators also connect Aich to the Islamic Jihad. But the US and Canada do not seek Aich’s extradition, and instead have the Irish police keep him under surveillance. He will escape from Ireland shortly before 9/11 (see June 3, 2001-July 24, 2001). [New York Times, 1/22/2000; Irish Times, 7/31/2002] Apparently, many of the documents seized in the raid will only be closely examined after 9/11. Documents will show that in 1999 and 2000, Mustafa Ahmed al-Hawsawi, a top al-Qaeda financier, worked with the Dublin cell to finance Moussaoui’s international travel. Aich made travel arrangements and possibly provided fake identification for Moussaoui. [Fox News, 7/30/2002; Irish Times, 7/31/2002] Presumably, had these links been discovered after the 1999 raid instead of after 9/11, events could have gone very differently when Moussaoui was arrested in the US in August 2001 (see August 16, 2001).
