Crew of Austrian Airlines flight OS82 decides to land in Sofia after receiving bomb threat, Bulgarian authorities say.

An Airbus A320 flight from Tel Aviv to Vienna has made an emergency landing in Bulgaria following a reported bomb threat, according to the Bulgarian Ministry of Transport.

Austrian Airlines flight OS82 was near the border with Romania when the crew received a bomb threat and decided to land in the Bulgarian capital, Sofia, the Transport Ministry said in a statement on Sunday.

Bulgaria’s Ministry of Defence said an air force MiG-29 fighter jet escorted the plane to Sofia airport.

Initial information showed the aircraft carried six crew members and 51 passengers, all of whom have all since disembarked, according to the Transport Ministry’s statement.

The airline told the AFP news agency that a security search of the aircraft was conducted.

“Once the search of the aircraft is complete, the passengers will be rebooked onto alternative flights as quickly as possible,” the airline said.

A crisis response team has been set up, and relevant authorities have launched an investigation into the incident, the Bulgarian Transport Ministry said.

According to aviation and flight tracking site FlightAware, Austrian Airlines 82 left the Ben Gurion airport in Tel Aviv on Sunday at 6:46pm local time (15:46 GMT) and landed about three hours later at Vasil Levski airport in Sofia at 9:43pm (18:43 GMT).

Flightradar24 data showed it entered Romanian airspace at about 9:10pm (18:10 GMT) before turning south and heading back towards Bulgaria.

Information from the flight-tracking platform ADS-B Exchange indicates the aircraft was transmitting squawk code 7700 – a signal for a general emergency – at around the same time.

Flydubai incident

Last month, a Flydubai plane carrying 174 passengers was on its way from the United Arab Emirates to Tel Aviv when a co-pilot allegedly attacked the pilot with an axe in an attempt to crash the plane.

The aircraft plunged about 17,000 feet (5,180 metres) before it was brought back under control by other Flydubai pilots after passengers and other crew subdued the alleged attacker.

The flight was diverted and forced to make an emergency landing at Prince Sultan bin Abdulaziz International Airport in Tabuk, northwestern Saudi Arabia.

Authorities in the UAE said the co-pilot was on a “suicide” mission to crash the plane at Israel’s Ben Gurion airport in Tel Aviv.

The co-pilot, Hamam Al-Hammami, an Omani national, has since been charged with terrorism offences in the UAE.

The Israeli government responded to the incident by ordering checks on the identities of all pilots flying into the country.

United States President Donald Trump has for the first time explicitly ruled out the use of a nuclear weapon against Iran, but has not denied US media reports that his administration is considering deploying the US’s most lethal non-nuclear munition, nicknamed the “mother of all bombs” in the near future.

In an interview published on Thursday by right-wing American news site Newsmax, Trump suggested he does not plan to use nuclear weapons, but also clarified that the devastating aerial weapon, the GBU-43/B Massive Ordnance Air Blast Bomb (MOAB – ‘mother of all bombs ) “is not nuclear”.

“I wouldn’t use nuclear. We don’t have to. We’re the greatest nuclear power in the world,” he told Newsmax.

The comments marked Trump’s first definitive statement on the nuclear topic following speculation about a possible atomic conflict earlier in the US and Israel’s war on Iran. They also appeared to confirm speculation that another phase of the war is imminent, likely after the US midterm elections on November 3.

Here’s what we know:

What did Trump say?

Trump told Newsmax that the US might indeed launch another strike on Iran’s nuclear sites, particularly on Pickaxe Mountain, where Tehran is believed to be hiding a nuclear facility deep under layers of granite.

He ruled out using a nuclear weapon or a tactical nuclear weapon.

“I wouldn’t use nuclear. We don’t have to. We’re the greatest nuclear power in the world,” he said.

He also clarified that the MOAB, which CNN reported the US government is considering using, “is not nuclear”.

Responding to a question about whether the MOAB is “tactical nuclear” – meaning smaller nuclear munitions – Trump reiterated that it is not.

“Well, the mother of all bombs is not nuclear,” Trump said. “It’s not nuclear at all. This is just an extremely large bomb.”

Trump declined to say whether he had authorised its use in Iran.

Trump also suggested renewed attacks are likely in the near future. The US cannot end the war now because it has to ensure Iran cannot produce a nuclear weapon, he argued, saying he believes that “if they had it, they would use it, in my opinion, instantaneously”.

Trump also reiterated that the war would end “very soon” whether by force or diplomacy and that oil prices would then drop.

When asked if he would put “troops on the ground”, Trump said: “No, I don’t see that, I don’t see it.” Earlier in the war, Trump had made comments regarding sending in troops, a move analysts said would be devastating for US soldiers because of Iran’s mountainous territory.

What is the ‘mother of all bombs’?

The MOAB carries a massive payload of about 8,500kg (18,000 pounds or 8.5 tonnes) of high explosives. It weighs 9,800kg (21,605 pounds or nearly 10 tonnes) – about the same as four cars – and is just over nine metres (about 30 feet) long. Stealth bombers are too small to carry it, so it has to be deployed by larger, Lockheed C-130 Hercules transporters.

It is designed to explode a few metres above the ground, sending out intense fireballs that can blast buildings and other hard-surface structures within a 1km radius, experts have told Al Jazeera. It is so powerful that a mushroom cloud from its blast has been seen 32km (20 miles) away in tests, the US Air Force has said.

“Its large explosive charge can produce devastating blast effects against exposed personnel, equipment and vulnerable structures,” Brussels-based military and weapons analyst Elijah Magnier said. “Its purpose is to generate an exceptionally powerful blast across a surface area.”

However, Magnier said there is doubt about whether using the massive surface explosive would be effective against deeply buried nuclear installations in Iran. He added that the terrain in Iran could be difficult for larger cargo aircraft to access.

What has Trump previously said about nuclear weapons?

Trump has never explicitly mentioned using a nuclear weapon, but he has also never ruled it out.

Speculation regarding whether Washington might use nuclear weapons was rife in the early days of the conflict, largely because of the extreme nature of Trump’s numerous threats against Tehran.

In April, for example, as Iran enforced a blockade on ships in the Strait of Hormuz, Trump posted on his Truth Social site that “…a whole civilisation will die tonight, never to be brought back again”, if Iran did not agree to a peace deal and reopen the strait.

He also threatened to destroy Iran’s infrastructure, saying a bombing campaign “will be Power Plant Day and Bridge Day, all wrapped up in one”, in Iran.

Experts widely interpreted his statements as a threat of nuclear destruction, but one that still failed to force Iran to the table.

Although Trump largely moved away from his sabre-rattling rhetoric in the following weeks, he reiterated at the United Nations General Assembly in New York last month that he could “annihilate” Iran. He also told the assembly that he believed a deal would emerge after the midterms.

What is a ‘tactical’ nuclear weapon?

“Tactical” nuclear weapons (TNW) are smaller nuclear munitions designed for the battlefield as opposed to strategic nuclear munitions designed for mass destruction.

Some perceive TNWs as having a lesser impact than an atomic bomb, but experts warn that their names are misleading and they can nevertheless be devastating. Their explosive yield, between 0.3 and 50 kilotons, can impact areas within a 500-600km radius.

The US dropped a 15-kiloton nuclear bomb on Hiroshima, meaning that weapon would today be considered a TNW. The US, North Korea and Russia have TNWs in their arsenals, although no country has ever used them. TNWs are not subject to any international treaties and are largely unregulated.

What might another US attack on Iran look like?

With Trump failing to rule out dropping the MOAB, analysts speculate that the US might launch another – perhaps final – intensive bombing campaign targeting Iran’s nuclear and defence sites, particularly Pickaxe Mountain.

The US could also continue its naval blockade on Iranian ports, while providing escorts for commercial ships through the Strait of Hormuz.

Iran has vowed to respond to escalatory strikes by targeting oil and digital infrastructure in neighbouring Gulf states.

Senior defence officials have also warned that Iran will invade its neighbours if the US launches a ground operation, although Trump appears to have ruled that out.

Earlier in the war, he hinted at the possibility of sending ground forces to retrieve some 400kg of “yellowcake” – highly enriched uranium that Washington and Israel claim Tehran has hidden underground.

Trump’s phone calls in March to Kurdish militia groups fighting Iran provoked speculation that Washington could coordinate with them for an invasion, although that did not happen.

Brazilian president and opposition candidate snub the final debate ahead of the presidential election.

Brazilian President Luiz Inacio Lula da Silva and his main opponent Flavio Bolsonaro have snubbed a chance at a final debate ahead of the first round of the presidential election on Sunday, while police ruled out a bomb threat outside the country’s Supreme Court.

Lula, instead of taking part in the debate, opted to appear on a popular podcast with millions of YouTube subscribers while his rival Bolsonaro accused the electoral court of “censorship” as a reason for his withdrawal.

Bolsonaro, son of the former Brazilian President Jair Bolsonaro, said during a live broadcast on Thursday on his social media channels that his decision not to participate in the debate was due to “censorship imposed by the electoral court”.

The right-wing candidate was referring to a decision that barred the debate broadcaster from keeping President Lula’s empty seat on stage.

The debate organised by TV Globo, the country’s most popular broadcaster, was set for Thursday and offered a final opportunity for the two presidential frontrunners to face off before polls open.

TV Globo said in a statement that the debate was cancelled because two rulings, one from the country’s electoral court and the other from the Supreme Court, had created “legal uncertainty” about the event.

Lula, 80, will face off against Bolsonaro in a first-round vote on Sunday, with polls giving him a slight advantage.

The pair are neck and neck in projections for a potential runoff on October 25, however.

Bomb scare

On the same day of the cancelled debate, Brazilian police ruled out a bomb threat outside the Supreme Court.

A suspect who “tried to jump the court’s fences” and “threw a backpack on top of a bus stop” had been arrested, the court said in a statement.

Authorities examined the backpack, which ultimately contained “only personal belongings,” military police spokesperson Raphael Broocke told AFP.

The suspect will remain in custody while the investigation continues, he added.

The Supreme Court has been criticised by the political right, notably for the 2025 conviction of ex-leader Jair Bolsonaro over a coup plot.

It has also become embroiled in a fraud scandal that has dominated the final weeks of the presidential campaign.
