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.

WikiLeaks is a media organisation and publisher of leaked documents. It is a non-profit and is funded by donations and media partnerships. It has published classified documents and other media provided by anonymous sources. It was founded in 2006 by Julian Assange, an Australian editor, publisher, and activist, who is currently challenging extradition to the United States over his work with WikiLeaks. Since September 2018, Kristinn Hrafnsson has served as its editor-in-chief. Its website states that it has released more than ten million documents and associated analyses. WikiLeaks' most recent publication of original documents was in 2019 and its most recent publication was in 2021. From November 2022, numerous documents on the organisation's website became inaccessible. In 2023, Assange said that WikiLeaks is no longer able to publish due to his imprisonment and the effect that US government surveillance and WikiLeaks' funding restrictions were having on potential whistleblowers.
