A former U.S. Army sergeant accused of conspiring with terrorists to murder Americans helped move Osama bin Laden from Pakistan to Sudan and trained members of his terrorist organization, according to newly unsealed court documents.

The FBI complaint filed in U.S. District Court in Manhattan suggested there was a close relationship between Ali Mohamed, 46, a native of Egypt, and bin Laden, the suspected mastermind of the Aug. 7 bombings of U.S. embassies in Kenya and Tanzania.

But it also showed frequent contact between the FBI and Mohamed over the last six years and indicated that Mohamed had even sought unsuccessfully at one point to work as a translator for the FBI.

The complaint alleged that Mohamed was telling the FBI as early as 1993 about bin Laden, who also is charged in the broad conspiracy case stemming from the bombings, which killed 213 people.

The document was one of many unsealed after the New York Times filed legal papers challenging whether the bulk of the documents in the case against Mohamed could remain sealed.

Mohamed trained members of bin Laden's al Qaeda terrorist organization and helped move bin Laden from Pakistan to Sudan in 1991, according to the FBI complaint signed by Special Agent Daniel Coleman.

"Mohamed stated that he did this because he loved bin Laden and believed in him," the complaint alleged. It also said Mohamed admitted he had trained people in war zones and added that war zones can be anywhere.

A message left Friday with Mohamed's lawyer, James Roth, was not immediately returned.

Mohamed left the U.S. Army in 1989 after three years of service. In the military, he taught soldiers in the special forces about Muslim culture.
