Torture is not only immoral and illegal, it is also counterproductive to effective intelligence gathering, an independent international security consultant has said.

Mark Fallon spent more than three decades with the US Government, mainly as a special agent with the Naval Criminal Investigative Service (NCIS).

Since the 1990s he has been working in counter-terrorism operations, particularly related to Al-Qaeda, and is the author of a forthcoming book on torture.

Mr Fallon participated in a panel discussion on torture organized by the UN human rights office, OHCHR, held on the margins of the UN General Assembly debate.

Dianne Penn caught up with him afterwards.
