IDF strikes Tofigh Daru factory in Tehran — fentanyl supplier to Iran chemical weapons program

Israeli forces struck the Tofigh Daru Company factory in Tehran on Tuesday March 31 (D32). The IDF said the factory was 'a principal supplier of fentanyl for the Organization of Defense Innovation and Research (SPND)' — Iran's Defense Ministry agency responsible for developing chemical and biological weapons. Israel claimed the fentanyl was being provided to a chemical weapons development unit, noting fentanyl is deadly at high doses. Tofigh Daru is owned by Iran's largest pension fund. Iran acknowledged the strike — the first time Tehran publicly confirmed an IDF hit on a specific civilian industrial facility in Tehran. Iranian FM Abbas Araghchi posted a picture of the damaged factory on X, writing: 'The war criminals in Israel are now openly and unashamedly bombing pharmaceutical companies.' Araghchi insisted the factory only supplied 'hospital drugs used in medical operations.' The strike is the most explicit IDF targeting of alleged chemical weapons supply infrastructure and generated significant international criticism given the factory's civilian pharmaceutical ownership. The NYT reported the strike under its Tehran pharmaceutical strike coverage.
