US says Wikileaks could 'threaten national security'
The United States has condemned as "irresponsible" the leak of 90,000 military records, saying publication could threaten national security.
The documents released by the Wikileaks website include details of killings of Afghan civilians unreported until now.
Three news organisations had advance access to the records, which also show Nato concerns that Pakistan and Iran are helping the Taliban in Afghanistan.
Pakistan has denied claims its intelligence agency backed the Taliban.
