LONDON. Thousands of leaked U.S. military papers from Afghanistan contain evidence of possible war crimes that must be urgently investigated, the founder of the whistle-blowing website that published the papers said.

 

Julian Assange, who set up WikiLeaks to expose perceived unethical behavior by government and business, accused U.S. forces of covering up civilian deaths and said sections of the report supported such accusations.

 

His website has held back an additional 15,000 documents while it decides whether their publication had security implications. Assange did not reveal the source of the leak.
