WikiLeaks, a website that publishes anonymously sourced documents, has released video footage of what it says is a US military attack on Iraqi civilians in Baghdad.
Al Jazeera cannot independently verify the footage, but WikiLeaks says the images are from a military video from 2007, in which 12 civilians were killed.
As Al Jazeera's Patty Culhane reports, some viewers may find the footage in the report disturbing.
