Explosions rock Iran’s Mahshahr Petrochemical Zone amid rising tensions

Iranian media reported several explosions at the Mahshahr Special Petrochemical Zone in southwestern Iran’s Khuzestan province on Saturday, April 4, 2026.

According to Fars News Agency, citing Khuzestan deputy governor for security Valiollah Hayati, powerful blasts occurred at around 10:47 a.m. local time (07:17 a.m. GMT). Three impacts and a massive explosion struck the industrial area.

Facilities Targeted

The strikes hit multiple key facilities, including Fajr-1, Fajr-2, Rejal (Redzhal), Amir Kabir, Bu Ali, and the Bandar Imam petrochemical complexes. These sites are part of the Persian Gulf Petrochemical Industries Company (PGPIC) and produce a wide range of chemicals, polymers, LPG, and other essential petrochemical products.

Rescue and firefighting teams were immediately dispatched to the scene, with smoke rising over the complex. All industrial units in the zone were evacuated as a precautionary measure.

Casualties and Damage

At least five people were injured in the attacks, according to Iranian officials and multiple media outlets. Preliminary assessments indicated a high chance of further civilian casualties, though the full extent of damage remains under evaluation. Parts of the Bu Ali and Bandar Imam complexes sustained visible damage.

Iranian Response

Iranian authorities attributed the aerial strikes directly to the United States and Israel, describing them as aggression against the country’s critical energy infrastructure. The incident follows a pattern of recent attacks on Iranian industrial and energy sites.

The Mahshahr Special Petrochemical Zone is one of Iran’s most important industrial hubs, playing a vital role in the national economy. International observers are monitoring the situation for potential impacts on regional energy production and environmental risks.
