Mustafa Ait Idir and five other men, all originally from Algeria, were arrested in October 2001 by the federal police in Bosnia and Herzegovina on suspicion of involvement in an alleged plot to bomb the US embassy in Sarajevo. Upon their release in January 2002 they were immediately rearrested and handed over to US forces. They were subsequently transferred to Guantánamo Bay. It is alleged that Mustafa Ait Idir had "associated with a known al-Qa'ida operative" while living in Bosnia. The name of this operative is not known to the tribunal's President and therefore nor to Mustafa Ait Idir.
