April 5, 2010 - Internet group WikiLeaks releases a video showing a 2007 US helicopter attack that killed a dozen people in the Iraqi capital, Baghdad, including two Reuters news staff.

Oct. 22 - WikiLeaks releases some 400,000 classified US military files chronicling the Iraq war from 2004 to 2009, the largest leak of its kind in US military history.
-- They involve subjects including abuse of Iraqi prisoners in US custody, Iraqi rights violations and civilian deaths.
Nov. 18 - A Swedish court orders Assange's detention as a result of an investigation begun in September by the prosecutor's office into allegations of rape, sexual molestation and unlawful coercion.

Dec. 7 - Assange is arrested by British police on a European warrant issued by Sweden and held in jail after a judge refuses to grant bail to the 39-year-old.
