HAMBURG — U.S. authorities will allow an Algerian convicted in a millennium bomb plot to testify in the German trial of a man charged in the Sept. 11 attacks, but the officials denied a request for two other terror suspects to testify, a judge said Tuesday.

Presiding Judge Albrecht Mentz said court officials would travel to the United States as early as the first week of December to question Ahmed Ressam, convicted in a plot to bomb the Los Angeles International Airport at the peak of travel around Jan. 1, 2000. His sentencing was delayed to allow him to testify against others accused of terrorism.

Ressam, a former Montreal resident, was arrested in Washington state on Dec. 14, 1999, while entering the United States from British Columbia in a car with a trunk full of explosives.

Ressam's connection to defendant Mounir el Motassadeq was not immediately clear, said the defendant's lawyer and a lawyer for an American widowed in the Sept. 11 attack, who has joined the trial as a co-plaintiff.

Germany's chief federal prosecutor, Kay Nehm, has cited information from Ressam as key to the indictment against el Motassadeq, but the court did not elaborate.

El Motassadeq, 28, faces life in prison if convicted of belonging to a terror organization and more than 3,000 counts of murder. Prosecutors accuse the Moroccan of helping arrange financial transactions and housing for members of the Hamburg terror cell that participated in the Sept. 11 attacks.

The court also requested testimony from al-Qaida suspects Ramzi Binalshibh and Zacarias Moussaoui, both in U.S. custody. The U.S. Justice Department refused without giving a reason, said lawyers who saw the letter sent to the court.

German federal prosecutors believe that Binalshibh, who fled Germany but was captured in Pakistan and turned over to the U.S. two months ago, was al-Qaida's key contact person in Hamburg.

Moussaoui, the so-called 20th hijacker, was arrested in August 2001 in Minnesota and faces a death-penalty trial as an alleged conspirator in the attacks.

The court still has pending requests for testimony from American investigators and others in U.S. custody.

In the 10th day of testimony, Angela Duile, a librarian at the Hamburg Technical University who was cited in el Motassadeq's indictment, said suicide pilots Mohamed Atta and Marwan al-Shehhi often sent e-mail from the library's computers and browsed what appeared to be religious Web pages in Arabic.

One day around closing time, Duile testified al-Shehhi appeared agitated then suddenly had an "outburst," ranting that he hated the United States.

"He said something will happen and there will be thousands dead, and mentioned the World Trade Center," Duile testified. "He was really upset."

Nehm had previously announced that the outburst was in April or May 2000, but Duile testified she only worked at the library until August 1999. She was to bring her journal Wednesday to clarify the date.

In other testimony, the girlfriend of suicide pilot Ziad Jarrah said he became increasingly devout after moving to Hamburg at the end of 1997, insisting she wear a veil, which she refused to do.

Jarrah - who took over the cockpit of United Airlines Flight 93, which crashed at Shanksville, Penn. on Sept. 11- left Germany from November 1999 to February 2000. He said he was visiting his parents in Lebanon, but Aysel Senguen testified she doubted that.

"At that time there were problems in Chechnya, and Ziad had talked about what he had seen on TV, so I thought he might have gone there to fight," said Senguen, a Stuttgart native of Turkish origin.

The time she described corresponds with when federal prosecutors say Jarrah was in Afghanistan with other Hamburg cell members, planning the attack and securing financial and logistical help.

Senguen said a man named Mounir called her while Jarrah was away offering help if she needed anything. She never knew his last name.

When Jarrah returned, he brought her dresses from Pakistan and jewelry from the United Arab Emirates but would not elaborate on his travels.

"He said, 'It is better that you don't know,' " she testified.

Jarrah started flight school in Florida in June 2000. The following January, Senguen visited him for 10 days there and saw him again in July when he stopped in Germany on the way back from Lebanon.

She last heard from him just hours before the Sept. 11 attacks, when he called from the United States.

"He told me three times that he loved me, and then he hung up," she said.
