REPEATED abuses allegedly suffered by three British prisoners at the hands of US interrogators and guards in the Guantanamo Bay detention camp in Cuba could amount to war crimes, the Red Cross said on Wednesday.

The organization, which maintains a rigidly neutral stance in public, took the unusual step of voicing its concerns in uncompromising language after the former detainees, known as the Tipton Three, revealed that they had been beaten, shackled, photographed naked and in one incident questioned at gunpoint while in US custody.

Their vivid account of the harrowing conditions at the camp, as told to their lawyers and published for the first time in Tuesday's London-based Guardian newspaper, has reignited the debate about the treatment of prisoners and the British government's role in their questioning and detention.

The other day the Red Cross was joined by the Medical Foundation for the Care of Victims of Torture, which argued that if the allegations were true they indicated systematic abuse, amounting to torture.

The Tipton Three were captured in Afghanistan and held at the US military base in Cuba for two years, before being released in March without charge. One man, Rhuhel Ahmed, alleged that a British soldier had interrogated him for three hours in Afghanistan while an American colleague held a gun to his head and threatened to shoot him.

The trio also said that they had repeatedly complained of abuse to British consular officials. "Some of the abuses alleged by the detainees would indeed constitute inhuman treatment," said Florian Westphal, spokesman for the International Committee of the Red Cross in Geneva.

"But we can't comment on this publicly since this type of allegation is raised directly in discussion with the detaining authority. "Inhuman treatment constitutes a grave breach of the third Geneva convention and these are often also described as war crimes."

The organization is allowed to visit the detainees to ensure they are treated in accordance with the Geneva conventions as long as it does not disclose information about conditions there. It can breach confidentiality in limited circumstances, most importantly, if going public would be in the best interests of the prisoners. -Dawn/The Guardian News Service.
