This has a decent description:

Specific mention of attack aircraft, not copters.

That's what I was reading from the HRW site as well, although the
connection between the aircraft and gas isn't direct. "In the
afternoon, at about 3:00, those who remained in the shelters became
aware of an unusual smell."

You may be right, for the reasons that you give concerning
antiaircraft threats in Kurdistan atthe time... but note that both the
LA Times and the Guardian quoted sources that said that the 214s had
been involved.
