A massive explosion and fire rocked a port in southern Iran on Saturday, purportedly linked to a shipment of a chemical ingredient used to make missile propellant, killing five people and injuring more than 700 others.
Mehrdad Hasanzadeh, a provincial disaster management official, gave the updated casualty figure in an interview on state television. The previous toll was four dead and more than 500 others injured.
The blast at the Shahid Rajaei port happened as Iran and the United States met Saturday in Oman for the third round of negotiations over Tehran’s rapidly advancing nuclear program.
While no one in Iran outright suggested that the explosion came from an attack, Iranian Foreign Minister Abbas Araghchi, who led the talks, had acknowledged Wednesday that “our security services are on high alert given past instances of attempted sabotage and assassination operations designed to provoke a legitimate response.”
Port reportedly received chemical for missile fuel
For hours, authorities in Iran offered no clear explanation for what caused the blast at the port, located just outside of Bandar Abbas, though they denied the explosion had anything to do with the country’s oil industry.
The port took in a shipment of “sodium perchlorate rocket fuel” in March, said private security firm Ambrey. The fuel was part of a shipment from China by two vessels to Iran, first reported in January by The Financial Times. The fuel was going to be used to replenish Iran’s missile stocks, which had been depleted by its direct attacks on Israel during the war with Hamas in the Gaza Strip.
“The fire was reportedly the result of improper handling of a shipment of solid fuel intended for use in Iranian ballistic missiles,” Ambrey said.
Ship-tracking data analyzed by The Associated Press put one of the vessels believed to be carrying the chemical in the vicinity in March, as Ambrey said. Iran hasn’t acknowledged taking the shipment.
The Iranian mission to the United Nations didn’t immediately respond to a request for comment on Saturday.
It’s unclear why Iran wouldn’t have moved the chemicals from the port, particularly after the Beirut port blast in 2020. That explosion, caused by the ignition of hundreds of tons of highly explosive ammonium nitrate, killed more than 200 people and injured more than 6,000 others. However, Israel did target Iranian missile sites where Tehran uses industrial mixers to create solid fuel.
Social media footage of the explosion on Saturday saw reddish-hued smoke rising from the fire just before the detonation. That suggests a chemical compound being involved in the blast.
“Get back! Get back! Tell the gas (truck) to go!” a man in one video shouted just before the blast. “Tell him to go; it’s going to blow up! Oh God, this is blowing up! Everybody evacuate! Get back! Get back!”
On Saturday night, the state-run IRNA news agency said that the Customs Administration of Iran blamed a “stockpile of hazardous goods and chemical materials stored in the port area” for the blast, without elaborating.
Port a major destination for Iranian cargo
Shahid Rajaei has been a target before. A 2020 cyberattack attributed to Israel targeted the port. It came after Israel said that it thwarted a cyberattack targeting its water infrastructure, which it attributed to Iran.
Social media videos showed black billowing smoke after the blast. Others showed glass blown out of buildings kilometres away from the epicentre of the explosion. State media footage showed the injured crowding into at least one hospital, with ambulances arriving as medics rushed one person by on a stretcher.
Hasanzadeh, the provincial disaster management official, earlier told state television that the blast came from containers at Shahid Rajaei port in the city, without elaborating. State television also reported that there had been a building collapse caused by the explosion, though no further details were offered.
The Interior Ministry said that it launched an investigation into the blast.
Iranian President Masoud Pezeshkian also offered his condolences for those affected in the blast.
Shahid Rajaei port in Hormozgan province is about 1,050 kilometres southeast of Iran’s capital, Tehran, on the Strait of Hormuz, the narrow mouth of the Persian Gulf through which 20 per cent of all oil traded passes.
