A federal judge in the United States has ordered that radical cleric Abu Hamza al-Masri be held in detention.
Hamza, 54, was extradited from Britain with four other men on Friday night and made a brief appearance in a New York court before Judge Frank Maas.
The ABC reports Hamza and Khaled Al-Fawwaz, Syed Tahla Ahsan, Adel Abdul Bary and Babar Ahmad arrived in the United States on Saturday. All face terrorism-related charges.
The Department of Justice said the court appearance was a prelude to a formal arraignment due Tuesday.
Hamza, 54, faces 11 charges. They include a kidnapping in 1998 in Yemen, the establishment of a terrorist training camp in the United States and "facilitating violent jihad in Afghanistan".
AFP reports he did not speak at the hearing.
Al-Fawwaz, 50, and Bary, 52, appeared in a separate hearing in Connecticut on Saturday.
They pleaded not guilty to charges with conspiring with members of Al Qaeda to kill US nationals and to attack US interests abroad.
They are also accused of being aides to the late Osama bin Laden.
The ABC reports Hamza rose to prominence after giving fiery sermons at the Finsbury Park mosque in north London, but has been in prison in Britain for eight years after being convicted of soliciting murder and inciting racial hatred.
