Mustafa Ahmad al-Hawsawi was one of two key financial facilitators entrusted by 11 September mastermind Khalid Shaykh Muhammad (KSM) to manage the funding for the hijackings. As a trusted, respected financial facilitator known to the leadership, al-Hawsawi separately met with Usama Bin Ladin, his deputy Ayman al-Zawahiri. and al-Qa'ida spokesman Sulayman Bu Ghayth soon after the attacks on 11 September and had contact with many of al Qa'ida's most senior managers.
Various reports suggest that al-Hawsawi had direct ties to several of the hijackers and to other operatives, including Ramzi Bin al-Shibh -- who delivered some money from al-Hawsawi to the hijackers. In addition, al-Hawsawi and Bin al-Shibh served as a communications link between KSM and the hijackers. He shared a United Arab Emirates (UAE)-based financial account with one hijacker -- an account that funded the hijackers' activities in the month before the attacks on 11 September. Four hijackers returned money directly to al-Hawsawi in the week before the attacks, which al-Hawsawi then redeemed in the UAE. Al-Hawsawi also wired thousands of dollars to Bin al-Shibh in the summer of 2001, per KSM's instructions. KSM also maintained his own financial links to al-Hawsawi. In 2001, KSM held a supplemental credit card linked to an al-Hawsawi account based in the UAE.
Al-Hawsawi worked in the al Qa'ida media center in Afghanistan from 2000 -- while it was under the direction of KSM -- until he departed for the UAE in early 2001.
After the attacks on 11 September, al-Hawsawi fled the UAE and traveled to Afghanistan and to Pakistan, where he hid until his capture in 2003. KSM reportedly had been providing a safehouse and other logistic support to guarantee al-Hawsawi's security after he arrived in Pakistan.
Hawsawi facilitated other operatives' travel, including Muhammad al-Qahtani, who was denied entry into the United Slates in the summer of 2001.
Hawsawi's close relationship with KSM and the latter's active participation in providing for his security following 11 September suggests Hawsawi was key to KSM's operational team. (Source)
