Another example is that of Ali A. Mohamed, an Egyptian psychologist and army officer awaiting sentencing in New York after pleading guilty for his role in the American embassy bombings in Kenya and Tanzania on August 7, 1998, that killed 224 people and injured thousands more.
A top al-Qaeda motivational leader and trainer, Mohamed instructed recruits in how to build bombs, blow up buildings, communicate in code, masquerade as normal Americans, and (in his words) create cell structures that could be used for operations.
Those he indoctrinated were responsible for some of al-Qaedas most notorious operations, including the 1990 assassination of Rabbi Meir Kahane and the 1993 World Trade Center bombing.
In between an estimated 58 trips from America to overseas destinations on various missions, he found time in the early 1990s and in 1995 to set up and to host fund-raising jaunts to the U.S. for Ayman al-Zawahiri, even though, then as now, the latter was one of the worlds most wanted terrorists.
During the 1995 tour, al-Zawahiri and Mohamed inspected possible U.S. targets. Money received from supporters during that trip funded the suicide bombing of the Egyptian embassy in Islamabad, Pakistan, in November 1995,11 in which 17 died.
Ayman Al-Zawahiri: attention turns to the other prime suspect
Al- Jihad members testified during the 1999 trial in Egypt that he had entered the USA in 1995 using the alias Dr Abdel Moez and while there raised funds used to finance the attack on the Egyptian embassy in Islamabad. According to Londons Guardian newspaper, the US House of Representatives judiciary subcommittee on immigration was told by a counterterrorism expert in January 2000 that al-Zawahiri was one of several Islamic militants who had been granted green card status by the US Immigration Service. Al-Zawahiri seems to have had vastly more experience in clandestine operations than Bin Laden.
