A huge blast on Saturday likely caused by the explosion of chemical materials stored at Iran's biggest port, Bandar Abbas, killed at least five people and injured more than 500, Iranian state media reported, reports Reuters.

The explosion, which hit the Shahid Rajaee section of the port, occurred as Iran began a third round of nuclear talks with the United States in Oman, but there was no immediate indication of a link between the two events.

Hossein Zafari, a spokesperson for Iran's crisis management organisation, appeared to blame the explosion on poor storage of chemicals in containers at Shahid Rajaee.

"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.

An Iranian government spokesperson, however, said that although chemicals had likely caused the blast, it was not yet possible to determine the exact reason.

Iran's official news channels aired footage of a vast black and orange cloud of smoke billowing up above the port in the aftermath of the blast, and an office building with its doors blown off and papers and debris strewn around.

Bandar Abbas is Iran's largest port and handles most of its containers in transit.

The blast shattered windows within a radius of several kilometres and was heard in Qeshm, an island 26 kilometres (16 miles) south of the port, Iranian media said.

The semi-official Tasnim news agency posted footage of injured men lying on the road being tended to amid scenes of confusion.

State TV earlier reported that poor handling of flammable materials was a "contributing factor" to the explosion. A local crisis management official told state TV that the blast took place after several containers stored at the port exploded.

As relief workers tried to put out fires, the port's customs officials said trucks were being evacuated from the area and that the container yard where the explosion occurred likely contained "dangerous goods and chemicals." Activities at the port were halted after the blast, officials said.

DEADLY INCIDENTS

A series of deadly incidents have hit Iranian energy and industrial infrastructure in recent years, with many, like Saturday's blast, blamed on negligence.

They have included refinery fires, a gas explosion at a coalmine, and an emergency repairs incident at Bandar Abbas killed one worker in 2023.

Iran has blamed some other incidents on its arch-foe Israel, which has carried out attacks on Iranian soil targeting Iran's nuclear programme in recent years and last year bombed the country's air defences.

Tehran said Israel was behind a February, 2024 attack on Iranian gas pipelines. And in 2020, computers at Shahid Rajaee were hit by a cyberattack. The Washington Post reported that Iran's arch-foe Israel appeared to be behind that incident as retaliation for an earlier Iranian cyberattack.

Israel has indicated it is nervous about the outcome of US-Iran talks, demanding a full dismantlement of Iran's nuclear programme. Tehran says the programme is used solely for peaceful purposes, while international observers say it is getting closer to being able to build a bomb.

There was no immediate comment from Israeli military or Prime Minister Benjamin Netanyahu's office when asked for comment on whether Israel was in any way involved in Saturday's explosion.

Oil facilities were not affected by the blast on Saturday, Iranian authorities said. The National Iranian Petroleum Refining and Distribution Company said in a statement that it had "no connection to refineries, fuel tanks, distribution complexes and oil pipelines."

MSH

At least 34 people, including two babies were killed when a contraband fuel depot exploded into flames in southern Benin near the border with Nigeria on Saturday.

According to Beninese Interior Minister Alassane Seidou, “a serious fire occurred in the town of Seme Podji. Another 20 people were seriously wounded in the incident.”

"I can't really give you the cause of the fire, but there is a large gasoline warehouse here and cars, tricycles and motorcycles come from morning to evening,” he added.

Nigeria is a main oil and gas producer where fuel smuggling is very common along its borders, particularly when the government maintains a subsidy to keep fuel prices low.

The majority of the victims were burnt and they could not be not be identified.

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
