Russia's ambassador to NATO says the publication by whistleblowing website Wikileaks of U.S. secret documents on the war in Afghanistan will lead to investigations conducted by countries involved in the war.

On Sunday, Wikileaks released some 91,000 U.S. military secret documents on the war in Afghanistan dating from September 2004 to December 2009.

The documents reveal the killings of civilians, reports that Pakistan's ISI intelligence agency is helping the Taliban in Afghanistan, with military units involved and weapon systems used. These documents were also given to a number of world acknowledged publications, such as the New York Times, the Guardian and Der Spiegel.

White House and other world authorities involved in the war called this move irresponsible.

Russia's envoy to NATO, Dmitry Rogozin, said he thinks that Washington's policies will not change much.

"I anticipate investigations... especially in the parliaments of those countries, including European countries, which in one way or another have been looking for an excuse to justify the need to relocate their European contingents out of the Afghani NATO forces," Rogozin said.

Earlier this year, the Wikileaks website posted a video showing U.S. troops firing repeatedly on a group of men, some of whom were unarmed, walking down a Baghdad street.

The website does not have a central office or any paid staff and its operations are run only by a small dedicated team and some 800 volunteers.

Wikileaks' founder, Australian activist Julian Assange, has no home address but he often pops up in Sweden and Iceland, where Internet anonymity is protected by laws. He is being hunted by Pentagon investigators and as is suspected of releasing confidential U.S. State Department documents.
