Iran Expected to Ramp Up Chemical, Biological Weapons Programs

Amid sustained international scrutiny of Iran’s nuclear program, missile development, and regional proxy network, new assessments point to a quieter and more troubling front as allegations grow that Tehran may be expanding work related to chemical and biological weapons capabilities.

According to a new report from the Begin-Sadat Center for Strategic Studies at Bar-Ilan University in Israel, the Islamist regime in Iran may be advancing efforts to significantly develop its chemical and biological weapons programs — a move experts warn would pose serious risks not only to Israel but also to the wider region and the Iranian population itself.

Iran’s chemical and biological research programs allegedly focus on a range of toxic agents, including blister agents like mustard gas, nerve agents such as sarin and Novichok, and substances that attack the lungs or blood and can cause suffocation. 

These reportedly also include biological threats such as anthrax, ricin, and botulinum toxins, as well as certain viruses, all of which can cause severe illness or death by disrupting the body’s nervous system, organs, or immune response.

Israeli officials have previously warned that the Iranian government has been developing dual-use chemicals, with both civilian and military applications, and may be channeling them to its regional proxy terrorist forces, raising fears they could be used to intensify proxy conflicts and destabilize the wider Middle East.

Tehran is also suspected of having used such agents to help suppress the nationwide anti-government protests earlier this year, which were violently crushed by security forces in a crackdown that left tens of thousands of demonstrators tortured, imprisoned, or killed.

Similar allegations have repeatedly emerged in the past, adding to a wider pattern of reported abuses against civilians and violations of human rights.

According to a report from Iran International, a medical staff member in Karaj said some detainees released during the January protests had reported body aches, lethargy, weakness, loss of appetite, nausea, and vomiting — all symptoms that may indicate possible drug-related poisoning.

Iran first began developing chemical weapons-related capabilities in the 1980s. In recent years, those efforts have reportedly evolved to include pharmaceutical-based agents and other compounds designed for incapacitation or riot control.

US government assessments have indicated for decades that Iran has been researching and developing chemical agents, including anesthetic compounds designed to incapacitate individuals by targeting the central nervous system.

These reports point to Iran’s academic sector playing a key role in this area, with Imam Hossein University and Malek Ashtar University of Technology — military-linked institutions associated with the Islamic Revolutionary Guard Corps and the Ministry of Defense — reportedly conducting research since at least 2005 into chemical agents designed for incapacitation.

Since the start of the war earlier this year, the Israeli Air Force has carried out sustained strikes targeting sites linked to chemical weapons research, development, and production, aiming to disrupt facilities embedded within Iran’s broader military-industrial infrastructure and associated pharmaceutical-based programs.

Even though Tehran has long denied pursuing chemical or biological weapons and remains a party to the Chemical Weapons Convention, Western governments continue to accuse the regime of violating international norms.
