explosion

Israel and the United States launched an air campaign against Iran on Saturday, striking Tehran and several other cities in what President Trump said was the start of “major combat operations.”

The attacks began with Israeli strikes Saturday morning — a workday in Iran — on Tehran, the capital, with residents speaking of attacks near the presidential palace and Iran’s National Security Council.

There were also reports of Israeli strikes on the Ministry of Intelligence, Ministry of Defense, the Atomic Energy Organization of Iran and a military complex.

Israel’s defense minister said the “pre-emptive strike” was to “remove threats against the State of Israel”.

It remains unclear the extent of the campaign and what its ultimate aim will be. But in an eight-minute recorded video message on Truth Social, Trump outlined a maximalist strategy that would see much of what he called “this very wicked, radical dictatorship from threatening America and our core national security interests.”

“We are going to destroy their missiles and raze their missile industry to the ground. … We are going to annihilate their navy. We are going to ensure that the region’s terrorist proxies can no longer destabilize the region or the world, and attack our forces,” he said. “And we will ensure that Iran does not obtain a nuclear weapon.”

He urged Iranians to take over their government.

“This will be probably your only chance for generations,” he said. “For many years, you have asked for America’s help, but you never got it. No president was willing to do what I am willing to do tonight.”

Trump also said U.S. military forces “may have casualties.”

Iran’s IRNA news agency quoted a source in the presidential office who said Iranian President Masoud Pezeshkian was unharmed in the strike.

Besides the capital, explosions could be heard in other the cities, including Isfahan, Karaj, Kermanshah and Qom, according to Iranian state media.

Both Israel and Iran shut down their airspace.

Cellphone and internet communications were disrupted shortly after the attacks began. Multiple Iranian state news websites also appear to have been hacked.

There was no immediate official response from Iran, but Ebrahim Azizi, the head of the Iranian parliament’s national security commission, vowed retaliation.

“We warned you!” he wrote on social media. “Now you have started down a path which end is no longer in your control.”

Residents reported hearing sounds of missiles flying over cities in Jordan, Syria and Lebanon in what was thought to be a missile barrage from Iran against Israel.

The attacks come two days after the U.S. and Iran concluded a third round of Oman-brokered negotiations in Geneva aimed at reducing tensions and stopping the prospect of war.

On Friday, Trump expressed displeasure with the pace of the talks, saying the Iranian side were not negotiating in “good faith” or giving in to U.S. demands. But Oman’s Foreign Minister Badr Albusaidi said a deal was “within reach.”

Local fire official says gas leak likely caused blast that ripped through residential building in Iranian port city.

An explosion that rocked a residential building in the Iranian port city Bandar Abbas was likely caused by a gas leak, the local head of the fire department told Iranian media.

The Bandar Abbas fire chief said residents were evacuated from the building in the city’s Moallem Boulevard area, Iran’s semi-official Tasnim news agency reported on Saturday.

“The initial cause of the building accident in Bandar Abbas was a gas leak and buildup, leading to an explosion. This is the initial theory,” fire chief Mohammad Amin Lyaghat said in comments broadcast on state television later.

The exact number of casualties was also not immediately clear.

Mehrdad Hassanzadeh, the head of crisis management in Hormozgan province, where Bandar Abbas is located, was quoted by the IRNA news agency as saying wounded people were being transferred to hospital, without reporting any deaths.

The Reuters news agency reported that a local official told Iranian news agencies that at least one person was killed and 14 others wounded. Al Jazeera could not independently verify that information.

State television said the explosion occurred at an eight-storey building, “destroying two floors, several vehicles, and shops” in the area.

Images carried by Press TV showed the building’s facade blown out, exposing parts of its interior, with debris scattered around.

The explosion took place amid soaring tensions between Iran and the United States and fears of a military confrontation between the two countries.

US President Donald Trump has repeatedly threatened to attack Iran over a recent crackdown on antigovernment protests and Washington’s push to curtail the Iranian nuclear programme.

After rumours circulated online about the Bandar Abbas explosion, the Islamic Revolutionary Guard Corps (IRGC) denied that any of the buildings belonging to its naval forces in the province had been targeted, according to a statement carried by the Fars news agency.

Bandar Abbas, home to Iran’s most important container port, lies on the Strait of Hormuz, a vital waterway between Iran and Oman that handles about a fifth of the world’s seaborne oil.

The port suffered a major explosion in April of last year that killed dozens of people and injured more than 1,000 others.

Separately on Saturday, four people were killed in a gas explosion in the city of Ahvaz near the Iraqi border, according to the state-run Tehran Times.

Crews had begun clearing the debris from that blast to rescue those trapped under the rubble, Press TV reported.
