Halabja chemical attack: The Kurdish town of Halabja in Iraq is attacked with a mix of poison gas and nerve agents on the orders of Saddam Hussein, killing 5,000 people and injuring about 10,000 people.

The Halabja massacre took place in Iraqi Kurdistan on 16 March 1988, when thousands of Kurds were killed by a large-scale Iraqi chemical attack. A targeted attack in Halabja, it was carried out during the Anfal campaign, which was led by Iraqi military officer Ali Hassan al-Majid. Two days before the attack, the city had been captured by Iran as part of Operation Zafar 7 of the Iran–Iraq War. Following the incident, the United Nations launched an investigation and concluded that mustard gas as well as unidentified nerve agents had been used against Kurdish civilians. The United States Defense Intelligence Agency initially blamed Iran for the attack, though the majority of evidence later revealed that Iraq had used the chemical weapons to bolster an ongoing military offensive against Iran, pro-Iranian Kurdish fighters, and ordinary Halabja residents.

Kurds, or the Kurdish people, are an Iranic ethnic group from West Asia. They are indigenous to Kurdistan, which is a geographic region spanning southeastern Turkey, northwestern Iran, northern Iraq, and northeastern Syria. Consisting of 30–45 million people, the global Kurdish population is largely concentrated in Kurdistan, but significant communities of the Kurdish diaspora exist in parts of West Asia beyond Kurdistan and in parts of Europe, most notably including: Turkey's Central Anatolian Kurds, as well as Istanbul Kurds; Iran's Khorasani Kurds; the Caucasian Kurds, primarily in Azerbaijan and Armenia; and the Kurdish populations in various European countries, namely Germany, France, Sweden, and the Netherlands.

Halabja is a city in the Kurdistan Region of Iraq and the capital of Halabja Governorate, located about 240 km (150 mi) northeast of Baghdad and 14 km (9 mi) from the Iranian border.
