Under interrogation following his capture, al-Qaeda leader Khallad bin Attash will say that after the bombing of the USS Cole (see October 12, 2000), Iran makes a concerted effort to strengthen relations with al-Qaeda. However, Iran is rebuffed because Osama bin Laden does not want to alienate his supporters in Saudi Arabia, which has poor relations with Iran. Nevertheless, Iranian officials are apparently willing to assist travel by al-Qaeda members through Iran, on their way to and from Afghanistan, by not placing telltale immigration stamps in their passports. Such arrangements are particularly beneficial to Saudi members of al-Qaeda. However, information such as this obtained from detainees under interrogation is thought to be unreliable due to the questionable methods used to extract it (see June 16, 2004).
