Pentagon: Leak site may have blood on its hands

THE whistle-blowing website WikiLeaks may have blood on its hands, the Pentagon has said, warning its unprecedented leak of secret US military files could cost lives and damage trust of allies.

An army intelligence officer, already under arrest, is at the centre of an investigation into the leak of more than 90,000 secret records to WikiLeaks, one of the biggest security breaches in US military history, officials have said.

Defence Secretary Robert Gates declined to comment on the probe but said he could not rule out more leaks of classified information.
