The United States received new intelligence from Israel indicating that Iran may be contemplating the deployment of chemical weapons against its foes, reports The New York Times (NYT), referencing multiple sources.

Sources indicate that Israel considers the chemical threat from Tehran to be more pressing than its nuclear aspirations.
Certain officials in the U.S. government and among Gulf states view this information as an effort by Benjamin Netanyahu’s administration to urge Washington to restart extensive military actions against Iran. Nonetheless, other officials stress that these warnings should be regarded with seriousness.
Experts remark that employing chemical weapons by Iran would be technically challenging to carry out. Additionally, Israel’s Home Front Command has not released any comprehensive guidance for the public regarding a chemical attack. Iran denies having such weapons, labeling these claims as psychological warfare.
