From videos of US military blunders to Guantanamo detainee files, Bradley Manning is accused of slipping 250,000 diplomatic cables and 500,000 classified military documents to WikiLeaks.

Washington is still investigating whether Assange encouraged Manning to disclose more details, in which case the Australian may be prosecuted in the United States.

While WikiLeaks has always denied knowing the source of the leaks, the US government says the documents were sent to the site from November 2009 until Manning's arrest in March 2010:

-- The first document published by WikiLeaks, on February 18, 2010, that Manning admitted to having leaked was a diplomatic cable from the US Embassy in Iceland.

-- What followed, in stages between February 2010 and September 2011, were more than a quarter of a million State Department cables from US embassies and consulates dated 1966 to 2010.

Starting in November 2010, five major news organizations around the world -- The New York Times, The Guardian, Der Spiegel, Le Monde and El Pais -- collaborated with WikiLeaks to partially publish the material.

-- Manning admitted to the "willful transmission" of a video that showed a US combat helicopter shooting at Iraqi civilians in July 2007. Dubbed "collateral murder" by WikiLeaks, the video was made public by Assange during a news conference in Washington in April 2010.

-- The soldier also acknowledged he had transmitted a confidential video of a US air strike on the Afghan village of Granai, where more than a hundred civilians lost their lives in May 2009.

-- More than 90,000 documents linked to the war in Afghanistan were published in July 2010, followed in October 2010 by more than 400,000 others connected to the conflict in Iraq. These included confidential Pentagon reports revealing abuse, torture and killings of civilians.

-- Confidential files made public since April 2011 of 779 detainees who passed through the military prison at Guantanamo Bay revealed that a majority of those incarcerated there had not been charged.

The documents also showed their mental state or the content of their statements, including those made by Khalid Sheikh Mohammed, the self-confessed architect of the September 11 attacks.–afp
