Tear gas is 100% a chemical weapon. Especially in the way that they used it.

To quote wikipedia: "Tear gas, formally known as a lachrymatory agent or lachrymator (from lacrima meaning "tear" in Latin), is a non-lethal chemical weapon that stimulates the corneal nerves in the eyes to cause tears, pain, and even blindness."
