Ray Wallace, forced to transport a technical component for Ahmed Amar, came to this address and handed it to Fayed. As Hasan Numair then worked to arm the first of five suitcase nukes, Fayed then left the place in charge of his lieutenant, Sabir Hussain, and moved to another safe-house. Ray remained with the others as a prisoner. When the CTUTAC team began their raid on the warehouse, they garrotted and knocked out some perimeter guards, but one sentry observed the intruders and alerted the main group. A shootout ensued, and the surviving terrorists knew they were cornered. To prevent its capture, the device was detonated prematurely by Numair, destroying the warehouse as well as every other building within a half mile radius and killing at least 12,000 people.
