Iraq's Secret War Files (WikiLeaks Special)In the biggest official files leak in history nearly 400,000 Iraq war logs reveal the massive scale of civilian deaths and new torture allegations following an investigation by Channel 4's Dispatches.

Channel 4 News has accessed the data in the classified documents via The Bureau of Investigative Journalism and WikiLeaks.

The only TV doc to have advance access to the biggest Wikileaks release ever. This is what really happened during the Iraq war, not what the US PR machine of the time wanted us to believe. The reality behind the civilian death count; al-Qaeda's fictitious presence; torture, torture and more torture. A wall of truth revealing unprecedented levels of unwarranted aggression.

Dispatches, Channel 4's flagship current affairs strand, exposes the full and unreported horror of the Iraqi conflict and its aftermath, revealing the true scale of civilian casualties and allegations that even after the scandal of Abu Ghraib, American soldiers continued to abuse prisoners.

And that US forces did not systematically intervene in the torture and murder of detainees by the Iraqi security services. The programme also features previously unreported material of insurgents being killed while trying to surrender.
