WikiLeaks says it will release CIA paper

WikiLeaks is preparing to release a leaked CIA paper sometime on Wednesday, the whistleblower website said.

"WikiLeaks to release CIA paper tomorrow," it said in a Tweet late on Tuesday also posted on its website, which is already locked in a dispute with the Pentagon over the leaking secret military documents on the Afghan war.

It published nearly 77,000 classified US military documents on the war in Afghanistan on July 23 and has said it will publish another 15,000 within the next couple of weeks.

The site, which has also previously leaked information leading to shocking revelations in places ranging from Iraq to Iceland, did not provide any further details about the CIA paper it planned to release.

WikiLeaks has been heavily criticised by US authorities and others for endangering lives with the Afghan leaks, and the site's founder Julian Assange has claimed the Pentagon could be orchestrating a smear campaign against him.

The 39-year-old Australian was at the weekend caught up in a media storm after Swedish prosecutors issued a warrant for his arrest on suspicion of rape, only to retract the order hours later.

Authorities are still, however, investigating a separate claim of molestation against Assange, and the former hacker has reportedly hired one of Sweden's top defence attorneys ahead of a looming decision by prosecutors about whether he will be prosecuted.
