More than 90,000 leaked US military records have been published on the website Wikileaks, reportedly revealing hidden details of the Afghanistan war.

Three major news publications which have been shown the documents say they include unreported killings of Afghan civilians.

The huge cache of classified papers is described as one of the biggest leaks in US military history.

The reports also suggest:

- The Taliban has had access to portable heat-seeking missiles to shoot at aircraft.
- A secret US unit of army and navy special forces has been engaged on missions to "capture or kill" top insurgents.
- Many civilian casualties have gone unreported, both as a result of Taliban roadside bombs and Nato missions that went wrong.
