Secret Afghanistan documents leaked

More than 91,000 secret documents relating to the US military in Afghanistan between 2004 and 2010 have been leaked by the WikiLeaks website.

According to the military reports, US officials in Afghanistan strongly suspected Pakistan was secretly supporting the Taliban while taking massive amounts of American aid.

The White House responded immediately with a strong condemnation of the disclosures, saying it could threaten national security and endanger the lives of Americans and those of its allies.

But Obama's national security adviser, Jim Jones, said the leak would not affect "our ongoing commitment to deepen our partnerships with Afghanistan and Pakistan."

The revelations contained in the classified documents could fuel growing doubts in Congress about Obama's war strategy when the US death toll is soaring and public support for the 9-year-old war is eroding.

Despite efforts by the White House to contain the political fallout, Senate Foreign Relations Committee Chairman John Kerry, one of Obama's closest Democratic allies, said the leaked documents raised "serious questions about the reality of America's policy toward Pakistan and Afghanistan."

The documents about Pakistan's alleged double-dealing could provide fodder for lawmakers who want to hold Obama to a timeline for withdrawing troops starting next July as well as increase pressure on the administration to outline a clear exit strategy.

One of them discusses a meeting of insurgents attended by a former senior Pakistani intelligence official who appears to be working against US forces in Afghanistan.
