A huge explosion ripped through Iran’s largest commercial port, killing at least eight people and injuring more than 700 others Saturday, in a fiery disaster authorities are linking to a shipment of chemicals used to create missile propellant.

The blast erupted at the Shahid Rajaee port in Bandar Abbas, a critical shipping hub on the Strait of Hormuz, sending a mushroom cloud of black and orange smoke towering above the coastline, Iranian state media reported. 

Initially, authorities provided no clear explanation as to what caused the blast in the port, only that it was linked to a fire that led to the explosion of several containers.

But more information surfaced from Iranian officials later Saturday — in addition to rising death tolls and injuries — suggesting the blast involved fuel intended for “Iranian ballistic missiles.”

“The fire was reportedly the result of improper handling of a shipment of solid fuel intended for use in Iranian ballistic missiles,” private security firm Ambrey said.

Purported footage from the scene emerged online revealing chaos on the ground — stunned workers fleeing collapsed buildings, motorists steering through streets littered with shattered glass, and emergency crews racing to pull survivors from under crumbled roofs. 

One video shows a raging fire growing stronger by the second as bystanders desperately attempt to flee.

The blast site appeared to leave behind at least three large black plumes of smoke from the port, according to a purported helicopter view of the site posted to X.

Some victims remained trapped under the wreckage Saturday afternoon, as firefighters battled the raging inferno, CNN reported.

Initial reports showed at least four people had died from the blast. As of 9:13 p.m. local time, the death toll had grown to eight, according to state media.

Authorities insisted that nearby oil infrastructure was untouched, with Iran’s state petroleum company stressing the explosion had “no connection” to refineries or fuel pipelines.

Still, the detonation rocked the city so hard that residents on Qeshm Island — 16 miles away — reported hearing it, Reuters reported.

The incident comes the same day that Iran and the US resumed nuclear talks in Oman.

Hossein Zafari, a spokesman for Iran’s crisis management organization, told the ILNA news agency officials had previously warned the Shahid Rajaee port about dangerous chemical storage practices.

In 2020, the same port suffered a suspected Israeli cyberattack targeting its computers.

Experts, however, cautioned pointing fingers at other nations. 

Jason Brodsky, policy director of the nonprofit United Against Nuclear Iran, posted to X that the explosion reminded him of recent reports about Iranian cargo ships docking at Bandar Abbas after departing China with missile components in late March.

Iran’s Interior Ministry has launched an investigation, but answers remain elusive as charred debris and plumes of smoke continue to choke the skyline over Bandar Abbas.

The ministry did not respond to The Post’s request for comment.
