WASHINGTON, June 18: The United States is holding terrorism suspects in more than two dozen detention centres worldwide and about half of these operate in total secrecy, said a human rights report released on Thursday.

Human Rights First, formerly known as the Lawyers Committee for Human Rights, said in a report that secrecy surrounding these facilities made "inappropriate detention and abuse not only likely but inevitable."

"The abuses at Guantanamo Bay and Abu Ghraib cannot be addressed in isolation," said Deborah Pearlstein, director of the group's US Law and Security programme, referring to the US Naval base prison in Cuba and Abu Ghraib prison in Iraq where abuses are being investigated.

"This is all about secrecy, accountability and the law," Pearlstein told a news conference. The report coincided with news that Defence Secretary Donald Rumsfeld ordered military officials to hold a suspect in a prison near Baghdad without telling the Red Cross. Pearlstein said this would be a violation of the Geneva Conventions and Defence Department directives.

She said thousands of security detainees were being held by the United States in Iraq and Afghanistan as well as locations elsewhere which the military refused to disclose.

"The US government is holding prisoners in a secret system of off-shore prisons beyond the reach of adequate supervision, accountability of law," said the report.

LIST OF CENTRES: Ms Pearlstein said multiple sources reported US detention centres in, among other places, Kohat, Pakistan, on the Indian Ocean island of Diego Garcia and at Al Jafr prison in Jordan, where the group said the CIA had an interrogation facility.

Prisoners are also being held at the Naval Consolidated Brig in Charleston, South Carolina, and others were suspected of being held on US warships. A defence department spokesman said he would comment when he had more information about the report.

Ms Pearlstein called for the US authorities to end "secret detentions", provide a list of prisoners, investigate abuses and allow the International Committee of the Red Cross unfettered access to detainees.

US treatment of detainees came under the spotlight after disturbing photos were leaked to the media showing US soldiers abusing Iraqi prisoners. The United States is conducting several investigations into these abuses but Ms Pearlstein said these were not enough and a full court of inquiry should be ordered.

Families of suspects detained by US authorities have complained strongly about the lack of information about detainees held by US authorities since the Sept. 11, 2001 attacks against the United States.

Farhat Paracha, a Pakistani, said via a telephone link-up at the news conference that she tried for weeks to find her husband, Saifullah Paracha, who disappeared last June when he took a business trip from Pakistan to Thailand.

Farhat said she asked the US and Pakistani governments to track him down and only learned about his whereabouts when the Red Cross contacted her six weeks later to say her husband was being held at Afghanistan's Bagram Air Force Base. "I feel disgusted. It makes my heart sink. I feel so powerless and so helpless," said Farhat Paracha. -Reuters
