Iran Port Explosion That Killed Dozens Blamed On Unregistered Rocket Fuel

A massive explosion purportedly linked to a shipment of a chemical ingredient used to make missile propellant has killed at least 40 people and injured more than 1,000 others in the southern Iranian port city of Bandar Abbas.

Authorities in Iran offered no clear explanation for what caused the April 26 blast at the Shahid Rajaei port, although independent experts said it appeared to be due to the improper storage of sodium perchlorate, a component used in rocket fuel.

On April 27, state media reported that the blast was now under control.

Iranian President Masud Pezeshkian visited with those some of the injured and told local officials that “we have to find out why it happened,” according to the government website.

The head of the Iranian Red Crescent Society, Pir Hossein Kolivand, said 190 of those injured remained hospitalized as of April 27.

Supreme Leader Ali Khamenei ordered security and judicial officials to investigate "any negligence or deliberateness" in the incident.

The Shahid Rajaei port is Iran's busiest, processing up to 80 percent of the country's shipping traffic.

Iran Port Fire Under Control After Dozens Killed

Hossein Zafari, a spokesman for Iran's crisis management organization, appeared to blame the explosion on poor storage of chemicals in containers at the port.

"The cause of the explosion was the chemicals inside the containers," he told Iran's ILNA news agency.

"Previously, the director general of crisis management had given warnings to this port during their visits and had pointed out the possibility of danger," Zafari said.

According to the private security firm Ambrey, the port had received a shipment of “sodium perchlorate rocket fuel” in March, which was going to be used to replenish Iran’s missile stocks after being depleted by its direct attacks on Israel during the war with Hamas -- which is designated as a terrorist group by the United States and the European Union -- in the Gaza Strip.

Tehran has not acknowledged taking the shipment, but ship-tracking data obtained by the Associated Press shows vessels believed to be carrying the chemical in the vicinity of the port in March.

Iran Launches Investigation After Port Explosion

Iran's Interior Ministry said it launched an investigation into the port explosion.

The April 26 blast happened as Iran and the United States met in Oman for the third round of talks over Tehran’s rapidly advancing nuclear program. A fourth round is scheduled for May 3, also in Oman.

While no Iranian officials have suggested the explosion was due to an attack, Iranian Foreign Minister Abbas Araqchi, who is leading Tehran's delegation in Oman, said earlier this week that "our security services are on high alert given past instances of attempted sabotage and assassination operations designed to provoke a legitimate response."

Deadly incidents have hit Iranian energy and industrial infrastructure in recent years -- such as gas explosions and oil refinery fires -- with many blamed on negligence.

Tehran, however, has also blamed some incidents on its arch-foe Israel, which has carried out attacks on Iranian soil targeting the country's nuclear program. Last year, Israel also bombed Iran's air defenses.

Iran accused Israel as being behind a February 2024 attack on Iranian gas pipelines, as well as a major cyberattack on the Shahid Rajaei port in May 2020, causing transport chaos for days after crashing the facility's computer system.

Israeli Prime Minister Benjamin Netanyahu on April 27 repeated his calls for "all of" Iran's nuclear infrastructure to be dismantled.

"We are in close contact with the United States. But I said, one way or the other, Iran will not have nuclear weapons," Netanyahu told a news conference.

The Shahid Rajaei port is Iran's largest and it mainly handles large volumes of container traffic and also has oil tanks and other petrochemical facilities.

The port is some 1,050 kilometers southeast of the capital Tehran, on the Strait of Hormuz, the narrow mouth of the Persian Gulf where 20 percent of all oil traded globally passes through.

Local officials said that all schools, universities, and offices in Bandar Abbas will be closed on April 27.
