In April 2010, WikiLeaks released the "Collateral Murder" video, which showed United States soldiers fatally shooting 18 civilians from a helicopter in Iraq, including Reuters journalists Namir Noor-Eldeen and his assistant Saeed Chmagh. Reuters had previously made a request to the US government for the "Collateral Murder" video under Freedom of Information but had been denied. Assange and others worked for a week to break the U.S. military's encryption of the video.
