Cheney enters 'torture' memos row

Former US Vice-President Dick CheneyDick Cheney has urged the CIA to release memos which he says show harsh interrogation techniques such as water-boarding work.

His comments follow the publication of memos written by Bush administration lawyers which justified the techniques.

Mr Cheney said that the decision to publish the memos was a mistake.

And it was misleading, he said, because the documents did not include those demonstrating that harsh interrogation delivered intelligence "success".

"One of the things that I find a little bit disturbing about this recent disclosure is that they put out the legal memos... but they didn't put out the memos that show the success of the effort," Mr Cheney said.

"There are reports that show specifically what we gained as a result of this activity. They have not been declassified. I formally ask that they be declassified now."

The American people should have a chance to weigh the intelligence obtained alongside the legal debate, he said.

Mr Cheney made his comments as US President Barack ObamaBarack Obama visited the CIA headquarters just outside Washington.

In a move seen as an attempt to boost morale, Mr Obama told employees that the CIA remained key to protecting the country.
