London, January 25 (RHC)-- A former senior British intelligence officer has revealed that the UK was aware of the torture of inmates at the notorious US military prison in Guantanamo Bay.

The former spy is seeking permission to present evidence to a forthcoming parliamentary inquiry that British officials saw detainees being tortured in December 2002, the Sunday Times said quoting senior security sources.

Details of torture were disclosed during meetings held at the London headquarters of Britain's MI5 in 2002 and the evidence is believed to include claims that British officials witnessed inmates being chained, hooded, waterboarded and subjected to mental abuse by CIA officials, the report said.

No one was immediately available to comment at Britain's Interior Ministry which handles media queries relating to MI5.

A report by the U.S. Senate published in 2014 said the CIA used sexual threats, waterboarding and other harsh methods to interrogate terrorism suspects in the years after the September 11, 2001, attacks in the United States.

A former British inmate at Guantanamo said last month that British security officers witnessed him being tortured by American soldiers in Afghanistan. Another former British prisoner at the camp said in 2014 he underwent psychological torture included execution threats and light deprivation.
