On July 12, 2007, a series of air-to-ground attacks were conducted by a team of two U.S. AH-64 Apache helicopters in Al-Amin al-Thaniyah, New Baghdad, during the Iraqi insurgency which followed the invasion of Iraq. On April 5, 2010, the attacks received worldwide coverage and controversy following the release of 39 minutes of classified gunsight footage by WikiLeaks. The video, which WikiLeaks titled Collateral Murder, showed the crew firing on a group of people and killing several of them, including two Reuters journalists, and then laughing at some of the casualties, all of whom were civilians. An anonymous U.S. military official confirmed the authenticity of the footage, which provoked global discussion on the legality and morality of the attacks.
