New FDD report warns of Iran chemical weapons program, alleges use against protesters as calls grow for OPCW and US probe
The Foundation for Defense of Democracies warns Iran may operate a covert chemical-weapons program and alleges Iranian forces used chemical agents against protesters in January 2026, prompting urgent calls for independent OPCW, UN and U.S. forensic investigations.
- FDD report argues Iran’s chemical program has been overlooked compared with its nuclear activities.
- More than 30 human-rights and civil society groups have asked the UN to investigate alleged chemical attacks on protesters.
- Eyewitnesses described effects inconsistent with ordinary tear gas — “What was fired was not tear gas.” and “people collapsed.”
- FDD urges immediate OPCW/UN and U.S. investigations and recommends considering strikes on chemical research and production sites if military action is pursued.

What the FDD report says
The FDD’s analysis warns that Iran’s chemical weapons program is opaque but dangerous. The think tank argues Western policymakers have prioritized Tehran’s nuclear activities while paying insufficient attention to potential chemical-weapons development and use, and warns oversight gaps may hide capabilities inside dual-use facilities.
The report links a surge of violence against protesters — beginning in December 2025 and continuing into January 2026 — with possible unconventional use of chemical agents by Iranian security forces. It documents multiple eyewitness accounts reporting effects more severe than normal law-enforcement tear gas and urges rapid forensic inquiry by independent investigators.

Eyewitness accounts and human rights pressure
According to the report, more than 30 rights and civil society organizations have asked the United Nations to investigate alleged chemical attacks on protesters in January 2026. These groups cite firsthand testimony of symptoms beyond typical tear-gas exposure: severe respiratory distress and sudden collapse.
“What was fired was not tear gas.”
“People collapsed.”
The FDD highlights patterns of symptoms across protest sites and stresses these allegations are serious and require verification by independent experts. It calls on the OPCW and UN to deploy investigators to gather environmental samples, medical evidence, and chain-of-custody documentation.
Legal obligations under the Chemical Weapons Convention
Iran is a party to the 1997 Chemical Weapons Convention (CWC), which bans development, production, stockpiling and use of chemical weapons and prohibits transfer or receipt of prohibited agents. The FDD stresses any use of chemical agents to suppress protests would breach Iran’s CWC obligations and violate international law.
The report recalls that U.S. officials have previously cited Tehran for failing to meet chemical-weapons commitments, a history that raises the stakes for timely, transparent investigation of new allegations.
Policy recommendations and calls for action
Andrea Stricker, deputy director of FDD’s Nonproliferation Program and author of the report, urged immediate investigations:
“The United States, its allies and the Organization for the Prohibition of Chemical Weapons (OPCW) should investigate credible claims that Iran’s regime used chemical weapons against its own people.”
Stricker also recommended that if Washington carries out military strikes tied to Iran’s nuclear activities, planners should seriously consider striking facilities linked to chemical-weapons research and production to degrade capabilities and deter future atrocities.
Uncertainty and the need for verification
The FDD is explicit that allegations are not yet proven in an international, forensic sense. The group calls for evidence-based, not political, responses: OPCW and UN teams should secure samples from sites and hospitals, interview witnesses, and analyze medical records to reach credible findings.
The report warns of a potential pattern whereby Tehran might use dual-use chemical facilities or covert labs to develop or test agents while global focus remains on the nuclear program — a strategic blind spot the FDD urges policymakers to close.
Broader context: nuclear diplomacy and escalation risk
The FDD release arrives amid fits-and-starts diplomacy with Iran: some officials press for renewed talks while others consider military options if Tehran refuses meaningful concessions on its nuclear program. The think tank contends the chemical-weapons dimension adds a troubling layer to any potential conflict and should inform planning.
If Washington opts for strikes, the report recommends planners consider chemical research and production sites alongside nuclear infrastructure to degrade capabilities that could be used against civilians or U.S. forces.
Implications for the United States
Economic and security impact: Verified Iranian chemical capabilities would raise direct security concerns for U.S. forces and allies in the region, influence force protection and readiness, and likely push planners to prioritize counter-CBRN measures and include chemical targets in contingency plans.
Political and diplomatic consequences: Confirmation of chemical-weapons use would increase pressure on Washington and partners to impose stricter sanctions, escalate diplomatic isolation, and pursue military options targeting chemical infrastructure; inaction could be seen as weakness.
Legal and humanitarian responsibilities: As a CWC state party and leading voice for international norms, the U.S. would be positioned to lead OPCW efforts for transparent investigations, evidence sharing, and accountability.
Domestic politics and readiness: Within the U.S., confirmation would intensify debate over the administration’s Iran strategy, likely mobilize conservative calls for decisive action, and prompt practical steps to bolster surveillance, protective gear distribution, and rapid medical response planning.
Next steps called for by analysts
The immediate priority, per FDD and allied experts, is an independent, transparent OPCW and UN investigation. For U.S. policymakers, recommended steps include pressing for site and victim access, sharing intelligence with international investigators, and keeping diplomatic and military options calibrated to deter further abuses. If investigations confirm chemical attacks, targeted action against production and research facilities should be part of the policy toolkit.
