October 22 - WikiLeaks releases some 400,000 classified U.S. military files chronicling the Iraq war from 2004 through 2009, the largest leak of its kind in U.S. military history.

-- They involve subjects including abuse of Iraqi prisoners in U.S. custody, Iraqi rights violations and civilian deaths.
