WikiLeaks Preparing to Release More Afghan Documents

LONDON -- WikiLeaks spokesman Julian Assange said Thursday his organization is preparing to release the rest of the secret Afghan war documents it has on file. The Pentagon warned that would be more damaging to security and risk more lives than the organization's initial release of some 76,000 war documents.

That extraordinary disclosure, which laid bare classified military documents covering the war in Afghanistan from 2004 to 2010, has angered U.S. officials, energized critics of the NATO-led campaign, and drawn the attention of the Taliban, which has promised to use the material to track down people it considers traitors.

The Pentagon says it believes it has identified the additional 15,000 classified documents, and said Thursday that their exposure would be even more damaging to the military than what has already been published.

Pentagon Press Secretary Geoff Morrell described the prospective publication as the "height of irresponsibility."

"It would compound a mistake that has already put far too many lives at risk," he said.

Speaking via videolink to London's Frontline Club, Assange brushed aside the Pentagon's demands that he stop publishing their intelligence. He gave no specific timeframe for the release of the 15,000 remaining files, but said his organization had gone through about half of them.

"We're about 7,000 reports in," he said, describing the process of combing through the files to ensure that no Afghans would be hurt by their disclosure as "very expensive and very painstaking."

Still, he told the audience that he would "absolutely" publish them. He gave no indication whether he would give the documents to media outlets The New York Times, The Guardian, and Der Spiegel -- as he has before -- or simply dump them on the WikiLeaks website.

The leaks exposed unreported incidents of Afghan civilian killings by NATO forces and covert operations against Taliban figures. Assange has said that hundreds of those reports should be investigated by the media for evidence of war crimes.

WikiLeaks' supporters say the blow-by-blow account of the conflict reveal the horror of the campaign's daily grind. Detractors say the site has recklessly endangered the war effort and Afghan informants working to stop the Taliban.

The Pentagon has a task force of about 100 people reading the leaked documents to assess the damage done and working, for instance, to alert Afghans who might be identified by name and now could be in danger.

Taliban spokesmen have said they would use the material to try to hunt down people who've been cooperating with what the Taliban considers a foreign invader. That has aroused the concern of several human rights group operating in Afghanistan -- as well as Paris-based media watchdog Reporters Without Borders, which on Thursday accused WikiLeaks of recklessness.

Jean-Francois Julliard, the group's secretary-general, said that WikiLeaks showed "incredible irresponsibility" when posting the documents online.

"WikiLeaks has in the past played a useful role by making information available ... that exposed serious violations of human rights and civil liberties which the Bush administration committed in the name of its war against terror," Julliard said in an open letter to Assange posted to his group's website.

"But revealing the identity of hundreds of people who collaborated with the coalition in Afghanistan is highly dangerous."

WikiLeaks, through its account on micro-blogging website Twitter, dismissed the letter as "some idiot statement, based on a bunch of quotes we never made."

While he acknowledged that some of the critiques leveled at his group were legitimate, he said the Pentagon -- as well as human rights groups -- had so far refused to help WikiLeaks purge the name of Afghan informants from the files.

At the State Department, spokesman Mark Toner said he was not aware of any effort by department officials to contact WikiLeaks.

Defense Department spokesman Col. David Lapan dismissed WikiLeaks' claims that they were reviewing the documents and removing information that could harm civilians.

"They don't have the expertise to determine what might be too sensitive to publish," he said. As for when the Pentagon expected WikiLeaks to release the documents, Lapan said: "WikiLeaks is about as predictable as North Korea."

A team of more than a hundred analysts from across the U.S. military, lead by the Defense Intelligence Agency, is poring over the WikiLeaks documents, according to defense officials who spoke on condition of anonymity to discuss matters of intelligence. Called the Information Review Task Force, the team is working out of the Crystal-City, Virginia-based Counterintelligence Collaboration Center.

The analysts are combing the documents, trying to determine the implications of the WikiLeaks release -- everything from whether military or intelligence-gathering tactics and procedures have been revealed and compromised, to whether specific intelligence sources have been endangered. They're also looking for incidents of civilian casualties that might not have previously been reported, anything concerning allies or coalition partners, and even "derogatory comments regarding Afghan culture or Islam."

The officials said the ultimate goal is to ensure the safety of U.S. and coalition members. The team is operating independently of an ongoing Army criminal investigation, and that of other law enforcement agencies, the officials said.

In the meanwhile, the U.S. has also reportedly urged its allies to look into Assange and his international network of activists, although it's not clear how aggressive Washington has been in prodding its foreign friends.

Earlier Thursday the Australian Foreign Minister Stephen Smith told The Associated Press that Washington had not approached the his government about pursuing possible criminal charges against Assange, an Australian citizen, or about putting restrictions on his travel.

"Quite clearly we're working closely with the United States on these matters," Smith said, citing Australia's Defense Department and the Pentagon as the agencies working together. "These are very serious matters for concern."

Australia, which has some 1,550 troops in Afghanistan, has already launched its own investigation into whether posting classified military documents had compromised the national interest or endangered soldiers.
