WASHINGTON (AFP) - Jordans King Abdullah II, a key US ally, said in an interview that there was enough evidence that the United States had engaged in torture using interrogation techniques shunned by the Obama Administration. What I see in the Press ... shows that there were illegal ways of dealing with detainees, King Abdullah told NBC in an interview to be broadcast Sunday on Meet the Press. Asked if the United States has engaged in torture, the King said there were enough accounts to show that that is the case. But there is still a major battle out there, he said, adding that he thought President Obama was making improvements to the American legal system. Abdullah spoke after holding talks with President Barack Obama on Tuesday, making him the first Arab head of state to meet with the new US President at the White House. The Obama Administration released four sensitive memos last week that blew the lid on harsh CIA terror interrogations approved under president George W. Bush, including the use of insects, simulated drowning and sleep deprivation. Obama has said that CIA officers involved in interrogations should not be prosecuted as they were acting on orders. But he has left the door open to possible prosecution of senior figures in the previous administration. Rights groups and some fellow Democrats have pressed Obama to go after top officials in the Bush administration for their role in the abuse and torture of detainees. The talks between Obama and King Abdullah focused on the stalled Middle East peace process. Meanwhile, a US military agency warned the administration of former US president George W Bush in July 2002 that torture of terrorism suspects usually yields unreliable information, The Washington Post reported late Friday. But the newspaper said that just a few weeks later, the Justice Department authorised use of harsh interrogation techniques on some captives in the war on terror. The unintended consequence of a US policy that provides for the torture of prisoners is that it could be used by our adversaries as justification for the torture of captured US personnel, the report quotes a document attached to a memorandum by the militarys Joint Personnel Recovery Agency as saying. Parts of the attachment, obtained in full by The Washington Post, were quoted in a Senate report on harsh interrogation released this week, the Paper said. According to The Post, it remains unclear whether the attachment reached high-ranking officials in the Bush administration. But the document offers the clearest evidence that has come to light so far that technical advisers on the harsh interrogation methods voiced early concerns about the effectiveness of applying severe physical or psychological pressure. The document was included among July 2002 memorandums that described severe techniques used against Americans in past conflicts and the psychological effects of such treatment, the paper said. The JPRA material was sent from the Pentagon to the CIAs acting general counsel, John Rizzo, and on to the Justice Department, according to testimony before the Senate Armed Services Committee. But in a memo dated August 1, 2002, the Justice Departments Office of Legal Counsel authorized the use of the 10 methods against Abu Zubaidah, an Al-Qaeda associate captured in Pakistan in March 2002, The Post pointed out.
