In the mid-1980’s, Khaled Abu el-Dahab, an Egyptian medical student, joins the militant group Islamic Jihad, and also meets Ali Mohamed. Mohamed convinces el-Dahab to move to the US and become a sleeper cell agent. El-Dahab does so in 1987, moving to Santa Clara, California, where Mohamed has a residence. El-Dahab marries an American woman, becomes a US citizen, and gets a job at a computer company. In 1987, a female acquaintance of el-Dahab enters his apartment unannounced and finds several men there cleaning rifles. She decides it is something she does not want to know about, and breaks off contact with him. In 1990, Mohamed and el-Dahab travel together to Afghanistan. They are financially supported by a network of US sympathizers, including two Egyptian-American doctors. Beginning in 1990, El-Dahab’s apartment becomes an important communications hub for al-Qaeda and Islamic Jihad cells all over the world. For much of the 1990’s, the Egyptian government cut direct phone links to countries like Sudan, Yemen, Afghanistan or Pakistan in an effort to disrupt communications between radical militants. So Dahab acts as a telephone operator for the Islamic Jihad network, using a three-way calling feature to connect operatives in far-flung countries. He communicates with bin Laden’s base in Sudan (where bin Laden lives until 1996). He receives phone calls from the likes of Islamic Jihad leader Ayman al-Zawahiri, who also visits California twice (see Spring 1993; Late 1994 or 1995). He distributes forged documents and makes money transfers. He is trained to make booby-trapped letters, enrolls in a US flight school to learn how to fly gliders and helicopters, and recruits additional US sleeper agents (see Mid-1990s). He helps translate US army manuals and topographical maps into Arabic for al-Qaeda and Islamic Jihad training. El-Dahab will move to Egypt in 1998 and get arrested in October of that year. He will confess his role in all of this in an Egyptian trial in 1999. The Egyptian government will sentence him to 15 years in prison (see 1999).
