Bin Laden supporters make they voices heard in Peshawar, Pakistan
Osama Bin Laden is under the control of the Taleban regime in Afghanistan and is being kept in hiding, according to the movement's ambassador in Pakistan.
"Osama is in Afghanistan, but he is at an unknown place for his safety and security," Mullah Abdul Salam Zaeef told reporters.
The Saudi-born militant is the United States' main suspect for the 11 September suicide hijacking attacks, and Washington has demanded that the Taleban hand him over or face punishment for sheltering him.
The Taleban ambassador said Washington could break the stalemate if it were willing to provide proof of Bin Laden's role.
"We say if they change and talk to us, and if they present evidence, we will respect their negotiations and that might change things."
There has been a lukewarm response to the announcement in Washington, with White House spokesman Ken Lisaius saying it "does not change anything".
"The president was extremely clear... that the demands that he outlined were not open to negotiation nor were they open to debate," he added.

A BBC Washington correspondent says White House officials are drawing a picture of a president spending another weekend in intense discussion with his closest security advisors.
Prince Sultan appears to have clarified Saudi policy
They say his message, repeated time and again, to those around him, is that nothing should deflect from the campaign to destroy terrorism.
However, Mr Bush has to deal with a weakening economy. He is understood to want to introduce a stimulus package next week that would increase unemployment benefits, tax cuts and the minimum wage.
Meanwhile, the FBI says it is following up over 100,000 leads.
More than a dozen British warships have arrived in the Gulf state of Oman, adding to speculation in the region that the US and Britain may launch military action soon.
'Nonsense'
Saudi Defence Minister Prince Sultan bin Abdul Aziz dismissed as "nonsense" reports that the Saudi authorities would allow Washington to use its bases to attack Afghanistan.
However, he did say Saudi airspace could still be used as his country's contribution.
"We do not accept the presence in our country of a single soldier at war with Muslims or Arabs," Prince Sultan said in comments published on Saudi Arabia's official Okaz newspaper on Sunday.
The US is gathering forces within striking distance of Afghanistan
The BBC Middle East correspondent says this is the clearest indication yet of where Saudi Arabia stands over the western military build up in the Gulf.
The comments imply that American planes could fly over Saudi Arabia but not launch an attack from its territory.
There has been much confusion over how far Saudi Arabia would work with the US since the 11 September attacks.
Saudi officials have hitherto been reluctant to comment publicly, apparently fearful of a backlash if Afghan civilians are killed in any military action.
Osama Bin Laden's main aims include the removal of US forces from Saudi Arabia, which he says defiles Islam, and overthrowing the Saudi monarchy.
