On July 12, 2007, two U.S. Army AH-64 Apache attack helicopters conducted a series of air-to-ground strikes in the Nouran neighborhood of Baghdad, Iraq. The incident resulted in civilian casualties and became one of the most scrutinized military engagements of the Iraq War. The attack killed at least nine civilians, including two Reuters journalists, and wounded four others. Video footage later released to the public showed the pilots' perspective during the engagement, capturing radio communications and thermal targeting imagery that sparked intense debate about rules of engagement, civilian protection, and the fog of war in urban combat zones.

The Apache helicopters involved were among the most advanced attack aircraft in the U.S. military arsenal. Each twin-turboshaft aircraft carried a 30 mm M230 chain gun mounted under its forward fuselage, along with AGM-114 Hellfire missiles and Hydra 70 rocket pods mounted on stub-wing pylons. Nose-mounted sensors provided nose-mounted thermal imaging for target acquisition and night vision capability, allowing pilots to operate effectively in low-light conditions. The aircraft's redundant systems were designed to withstand significant combat damage, making it a cornerstone of American air support operations throughout the Iraq War.

The Baghdad engagement occurred amid escalating sectarian violence in Iraq's capital. U.S. forces conducted daily air operations in support of ground troops, and Apache helicopters were frequently called upon to provide close air support during firefights. In this case, pilots reported receiving fire from the area and identified what they believed to be armed insurgents. The subsequent strikes were tactically consistent with military doctrine, yet the civilian toll raised critical questions about target identification protocols in congested urban environments where combatants and non-combatants were often intermixed.

The incident gained renewed prominence in 2010 when WikiLeaks released classified video footage titled "Collateral Murder," transforming a localized tragedy into a global flashpoint for debates about civilian casualties in modern warfare. The Apache strike became emblematic of the broader challenges facing military forces conducting counterinsurgency operations in populated areas, influencing policy discussions on targeting procedures, civilian harm mitigation, and investigative accountability that continue to shape military protocols today.
