A Briton being held by US forces in the southern Afghan city of Kandahar has been named.
He is Jamal Udeen, 35, from Manchester. The British foreign office gave no further details. It was unclear whether Mr Udeen would join three other Britons being held at a US facility in Cuba.
Another man currently being held in Kandahar was named last Monday as Ruhel Ahmed, but no details of where he was from in Britain were given.
The three Britons being held at Camp X-Ray prison camp in Cuba are Shafiq Rasul, 24, and Asif Iqbal, 20, from the central England town of Tipton, and Feroz Abbasi, 22, from south London.
The three are suspected of having links to al-Qaeda, the network headed by Saudi-born dissident Osama bin Laden, who is suspected of masterminding the September 11 attacks on the United States and is the target of a US-led war on terror.
