The Halabja chemical attack (), also known as the Halabja Massacre or Bloody Friday, was a massacre of Kurdish people that took place on 16 March 1988, during the closing days of the Iran–Iraq War in the Kurdish city of Halabja in Iraqi Kurdistan. The attack was part of the Al-Anfal Campaign in Kurdistan, as well as part of the Iraqi Army's attempt to repel the Iranian Operation Zafar 7. It took place 48 hours after the capture of the town by the Iranian Army. A United Nations (UN) medical investigation concluded that mustard gas was used in the attack, along with unidentified nerve agents.
