A report on Halabja massacre, Sarin and Iran–Iraq War

The Halabja massacre (Kêmyabarana Helebce کیمیابارانی ھەڵەبجە), also known as the Halabja chemical attack, was a massacre of Kurdish people that took place on 16 March 1988, during the closing days of the Iran–Iraq War in Halabja, Iraq.

It is generally accepted that "a lethal cocktail of mustard gas and the nerve agents Tabun, Sarin and VX" was used, as reported by the BBC.

March 1988: Halabja chemical attack; Over two days in March, the ethnic Kurdish city of Halabja in northern Iraq (population 70,000) was bombarded by Saddam Hussein's Iraqi Air Force jets with chemical bombs including sarin. An estimated 5,000 people died, almost all civilians.

April 1988: Sarin was used four times against Iranian soldiers at the end of the Iran–Iraq War, helping Iraqi forces to retake control of the al-Faw Peninsula during the Second Battle of al-Faw.

While little known outside of Iran (unlike the later Halabja massacre), the Sardasht bombing (and future similar attacks) had a tremendous effect on the Iranian people's psyche.

According to Foreign Policy, the "Iraqis used mustard gas and sarin prior to four major offensives in early 1988 that relied on U.S. satellite imagery, maps, and other intelligence. ... According to recently declassified CIA documents and interviews with former intelligence officials like Francona, the U.S. had firm evidence of Iraqi chemical attacks beginning in 1983."
