A huge cache of secret US military files released by Wikileaks paints a devastating portrait of the failing war in Afghanistan. It reveals how coalition forces have killed hundreds of civilians in unreported incidents, Taliban attacks have soared and Nato commanders fear neighbouring Pakistan and Iran are fuelling the insurgency. The whole thing is available online through The Guardian's purpose-built hub, which has video instructing you how to navigate the logs and live blogging as the news is trickled out. It's an astonishing piece of journalism. Click the picture below to go through to it.

The disclosures come from more than 90,000 records of incidents and intelligence reports about the conflict obtained by the whistleblowers' website Wikileaks in one of the biggest leaks in US military history. The files, which were made available to the Guardian, the New York Times and the German weekly Der Spiegel, give a blow-by-blow account of the fighting over the last six years, which has so far cost the lives of more than 320 British and more than 1,000 US troops.

No fee was involved and Wikileaks was not involved in the preparation of the Guardian's articles.
