Mr al-Libi is being held by US forces in Kandahar where many other al-Qaeda and Taleban soldiers are.
Earlier one of the world's most wanted men, Taleban leader Mullah Mohammad Omar, escaped his hideout in the area of Baghran on a motorbike, according to reports.
But now Afghan authorities say they know where he is and he will not escape again.
No sign of Bin Laden
Meanwhile the leader of the US military operation in Afghanistan, General Tommy Franks, said they still don't know where Osama Bin Laden is.
Earlier it was also reported an American special forces soldier had been killed in a gunfire battle. He's the first US soldier to die from enemy fire since the war in Afghanistan started.
