Q&A: Abu Hamza extradition process
Abu Hamza has always denied involvement in terrorism
Radical Muslim cleric Abu Hamza has been arrested on an extradition warrant issued by the US government.
BBC Home Affairs Correspondent Danny Shaw takes a look at what will happen next.
Why has Abu Hamza been arrested?
Because the American authorities want to begin criminal proceedings against him on terrorism-related matters.
To do that, they have to request his extradition from the UK, and that involves arresting him.
What happens now?
The details of the extradition request - essentially the allegations against him - were put before him at an initial hearing.
That took place at Bow Street Magistrates Court sitting at Belmarsh in south-east London.
Abu Hamza was also expected be informed that he may consent to go to the United States.
What are the charges?
Mr Hamza faces 11 charges including conspiracy to take hostages and hostage-taking in connection with an attack in Yemen in 1998.
He is also charged with providing support and resources to terrorists, specifically al-Qaeda, attempting to set up a training camp for "violent Jihad" in Bly, Oregon, in 1999, attempting to set up a terror training camp in Afghanistan and supporting the Taleban.
US Attorney General John Ashcroft outlined the charges at a press conference in New York at the same time as Mr Hamza was appearing in court in London.
The Crown Prosecution Service is acting as an agent to the US authorities in this case, so it will disclose the allegations in court.
What will happen to Abu Hamza in the meantime?
The District Judge - who is a paid magistrate - decided to keep him in custody rather than release him on bail.
Normally if the matters are terrorism-related it is highly unusual for suspects to be allowed out on bail - certainly that's been the experience recently.
How long is this whole extradition process likely to take?
The full extradition hearing will probably take place in about two months.
If the judge decides that all of the conditions for extradition have been met then he will send the case to the home secretary who decides whether or not to order the extradition.
That decision has to be taken within another two months.
Abu Hamza has the right to appeal and that process could take another two to three months if not longer.
So, the process could be wrapped up by the summer, but more realistically it will probably last into the autumn or winter.
