Radical cleric Abu Hamza will appear in court in New York on Tuesday for a plea hearing following extradition to the US to face terrorism charges.
He is due to be arraigned this morning before US District Judge Katherine B Forrest, who will also hold an initial pre-trial conference.
Hamza touched down in America on Saturday after he was kicked out of the UK following a failed appeal against extradition at the High Court on Friday.
Hamza will appear in court on Tuesday
Within hours of landing, the former imam at the Finsbury Park mosque in north London found himself in a Manhattan courtroom facing terror charges. But he did not enter a plea or make an application for bail during the brief hearing.
Hamza arrived in court without the hook he uses as a hand, and complained through his lawyer that he wanted it to be given back.
He was jailed in the UK for seven years for soliciting to murder and inciting racial hatred in 2006 and first faced an extradition request from the Americans in 2004.
He has been charged with 11 counts of criminal conduct related to the taking of 16 hostages in Yemen in 1998, advocating violent jihad in Afghanistan in 2001, and conspiring to establish a jihad training camp in Bly, Oregon, between June 2000 and December 2001.
Four other men - Khaled Al-Fawwaz, Adel Abdul Bary, Syed Ahsan and Babar Ahmad - who also had last-ditch extradition challenges thrown out in London, pleaded not guilty to other terror charges.
Ahmad, a computer expert from south London, and Ahsan are accused of offences including using a website to provide support to terrorists and conspiracy to kill, kidnap, maim or injure persons or damage property in a foreign country.
They were arraigned in New Haven in Connecticut.
Bary and Al-Fawwaz were allegedly involved in, or supported, the bombing of US embassies in Nairobi and Dar es Salaam in 1998.
They appeared alongside Hamza in New York.
The High Court ruled on Friday that the five men had lost their grounds for appeal and within hours they were placed on flights to the US.
They had been fighting extradition for between eight and 14 years.
Previously Home Secretary Theresa May rejected claims that the delays were in part down to the failure of Home Office officials to expedite proceedings.
She said: "We have acted as properly and as quickly as we can at every stage in this."
