The US State Department found both sides were using chemical weapons."There are indications that Iran may also have used chemical artillery shells in this fighting," spokesman Charles Redman told the press a week after the attack. "We call on Iran and Iraq to desist immediately from the use of any chemical weapons."

Defense Department reconstruction of the final stages of the Iran-Iraq war has assembled what analysts say is conclusive intelligence that one of the worst civilian massacres of the war, in the Iraqi Kurdish city of Halabja, was caused by "repeated chemical bombardments from both belligerent armies." "
Washington Post (May 3, 1990)
The US government itself later confirmed the fact that both sides had used gas and that, in all likelihood, Iranian gas killed the Kurds.A
Pentagon report, ‘Iraqi Power and U.S. Security in the Middle East’ published in 1990 states (Chapter 5): “In March 1988, the Kurds at Halabjah were bombarded with chemical weapons, producing a great many deaths. Photographs of the Kurdish victims were widely disseminated in the international media. Iraq was blamed for the Halabjah attack, even though it was subsequently brought out that Iran too had used chemicals in this operation, and it seemed likely that it was the Iranian bombardment that had actually killed the Kurds.”

Pentagon's USAWC and US Marine Corps reports concluded Iran gassed the Kurds at Halbjah, not Iraq.

"The great majority of the victims seen by reporters and other
observers who attended the scene were blue in their extremities. That means that they were killed by a blood agent, probably either cyanogen chloride or hydrogen cyanide. Iraq never used and lacked any capacity to produce these chemicals. But the Iranians did deploy them. Therefore the Iranians killed the Kurds."
US Marine Corps document FMFRP 3"Blood agents were allegedly responsible for the most infamous use of chemicals in the war—the killing of Kurds at Halabjah. Since the Iraqis have no history of using these two agents—and the Iranians do—we conclude that the Iranians perpetrated this attack."

The
DIA's report concluded Iran had gassed the Kurds & Iranians of Halabjah;
Immediately after the battle the United States Defense Intelligence Agency investigated and produced a classified report, which it circulated within the intelligence community on a need-to-know basis. That study asserted that it was Iranian gas that killed the Kurds, not Iraqi gas.
The agency did find that each side used gas against the other in the battle around Halabja. The condition of the dead Kurds' bodies, however, indicated
they had been killed with a blood agent - that is, a cyanide-based gas -which Iran was known to use. The Iraqis, who are thought to have used mustard gas in the battle, are not known to have possessed blood agents at the time.

CIA's report mentions "hundreds" killed, not "5000" and against the Iranians primarily w Kurds caught in the cross-fire. This report is still on the US government website.
