The Pentagon has demanded that the whistleblowing website WIKILEAK immediately hand over about 15 thousand documents on war on Afghanistan that the site has not published so far. 75 thousand other files have already posted online giving details of the deaths of civilians and military operations.The public disclosure last week of classified military documents by Wikileak sparked anger and alarm at the Pentagon and the concern has been heightened by reports that the whistleblowing webite has further 15,000 documents. At a news conference, the Defence Department spokesman said, the actions of Wikileak have threatened security of coalition troops and Afghan civilians working with them.
