Fathur Rohman Al-Ghozi, an Indonesian and key al-Qaeda member
operating from the Philippines. He is one of two foreign handlers
of the Singapore JI cells.
A bombmaker, he had in his possession more than a ton of TNT,
hundreds of detonators and more than a mile of detonating cord. The
other foreign handler, a Canadian national of Kuwaiti descent, is
still at large.
Yazid Sufaat, a Malaysian and another important al-Qaeda-linked
operative, had already obtained and stored 4 tons of ammonium
nitrate in a Malaysian town 100 miles north of Singapore.
Sufaat had housed two of the Sept. 11 bombers in Kuala Lumpur when
they were en route to America for the attacks. The two handlers
asked the Singaporeans to purchase another 17 tons of nitrate,
bringing the total to 21 tons, for seven bombs -- each the size of
the Oklahoma City bomb.
When all was ready, the two handlers were to assemble seven truck
bombs and direct where they were to be placed and detonated
simultaneously. (They knew that after one explosion, security would
be tightened.)
The arrests of the Singapore cells thwarted the handlers' plans,
which, had they succeeded, would have caused many American and
Singaporean casualties and horrendous damage.
