The Israel Defence Forces struck the Mahshahr Petrochemical Complex on 5 April, Iran's largest, responsible for an estimated 70% of domestic gasoline production. The same day, IDF strikes hit air defence systems and ballistic missile arrays in Tehran and the al-Shalamcheh border crossing between Iraq and Iran.
The Mahshahr strike marks a shift in targeting logic. Previous Israeli operations focused on export infrastructure: refineries, terminals, pipeline nodes. Mahshahr supplies the domestic market. Destroying 70% of a country's gasoline production capacity is a material reduction in the civilian population's access to fuel and transportation. The distinction between strategic and civilian-impact targeting has narrowed considerably.
The 100-plus US legal experts who raised IHL concerns about university strikes will find sharper grounds here. Export infrastructure has a clearer dual-use military rationale. A petrochemical complex that supplies civilian petrol does not. The humanitarian consequences will be measured in fuel shortages affecting transportation, agriculture, and heating within days.
Reconstruction of a facility of this scale requires years under normal conditions and is effectively impossible under the current sanctions framework, which restricts the import of industrial equipment. Iran's domestic fuel crisis, already strained by wartime disruption, enters a new phase.
