The White House has attacked online whistleblowing site Wikileaks after it published some 200,000 pages of secret American military files about the war in Afghanistan.
The files, published online by The Guardian, the New York Times and Germany's Der Spiegel, include details of 144 incidents in which Coalition forces have killed civilians.
The Guardian says the leaks show that troops killed hundreds of civilians in previously unreported incidents.
In one example cited by the British paper, French troops fired at a bus full of children, injuring eight.
A US patrol was involved in a similar incident that wounded or killed 15 passengers, and in 2007 Polish troops fired mortars at a village, apparently in a revenge attack, killing guests at a wedding party which included a pregnant woman.
According to the New York Times they also "suggest that Pakistan, an ostensible ally of the United States, allows representatives of its spy service to meet directly with the Taliban."
Describing the talks as "secret strategy sessions," the newspaper said they "organise networks of militant groups that fight against American soldiers in Afghanistan, and even hatch plots to assassinate Afghan leaders."
The Guardian says the files revealed a secret black-ops unit which hunts down Taliban leaders for "kill or capture" without trial; how the US covered up evidence of surface-to-air missiles acquired by the Taliban; and how the Taliban have caused growing carnage with their roadside bombing campaign, killing more than 2,000 civilians to date.
