3 years ago today, on April 5, 2010 Wikileaks released this leaked video footage from a U.S. Apache attack helicopter, which shows Reuters journalist Namir Noor-Eldeen, driver Saeed Chmagh, and about a dozen other people standing around together as the Apache blows them all to pieces with 30mm cannons, in a public square in Eastern Baghdad in 2007.
After the helicopter murders this group, a minivan arrives on the scene and some people attempt to transport some of the wounded to a hospital. These rescuers are fired upon as well, along with the children they had in the vehicle.
The official statement on this incident initially listed all adults as insurgents and claimed the US military did not know how the deaths occurred. They refused to release the video to Reuters, for an investigation of the murders. But fortunately for us, and unfortunately for them, Private Bradley Manning released the video to the folks at Wikileaks, who decrypted it and shared it under the name "Collateral Murder".
