Nuclear Weapons

US President Donald Trump warns that United States forces are ‘locked and loaded’ and ready to strike if necessary.

Iran’s foreign minister, Abbas Araghchi, has warned that Tehran will “rain down hell” if the United States resumes attacks, serving Washington with an ultimatum in an attempt to end the two countries’ eight-month war.

“Our 2-day proposal stands: meet the requirements, including end to war on all fronts, and you will see results,” Araghchi wrote in a post on X on Sunday.

“Or choose war, and see our alert and battle-hardened warriors rain down hell,” he said.

US President Donald Trump said on Sunday that renewed strikes on Iran are “highly unlikely” if negotiations progress over Tehran’s nuclear programme and the reopening of the Strait of Hormuz.

‘Locked and loaded’

“It depends on whether or not they sign a very strong agreement,” Trump said when asked about continued US strikes on Iran during a phone interview reported by CNN. “I would [continue], if necessary, but we hit them really hard,” he added.

Trump warned that US forces have three aircraft carriers stationed in the region “fully locked and loaded”, ready to continue strikes if need be. He also said that the US has 38 bridges in Iran’s crosshairs that US forces “can knock down in literally one hour”.

Iran’s Foreign Ministry also quoted Araghchi in an earlier statement on Sunday that said Iran would “not go easy on American targets” in the region.

Araghchi’s statements came after reports by state media that an oil tanker caught fire earlier that morning after hitting a naval mine east of the Strait of Hormuz, citing Iran’s navy.

The navy claimed the ship’s identification systems were turned off and it was travelling in the no-go zone of the strait.

‘Devastating and severe’ response

An adviser to Iran’s commander of the Islamic Revolutionary Guard Corps’ Aerospace Force made threats that echoed those of the Iranian foreign minister and said that weapons have been “secured for years to come”.

“The armed forces are at the ready, and if the enemy makes a mistake, Iran’s response will be devastating and severe,” warned IRGC Brigadier-General Ali Belali in a statement on Telegram.

“As senior commanders of the armed forces have pointed out, we have upgraded our capabilities in the post-Ramadan War period,” Belali said.

The back-and-fourth between Iranian and US leaders comes following US midterm elections in which the Democratic Party won control of both chambers of Congress, soundly defeating Trump’s Republican Party.

Araghchi alleged that negotiations have been delayed as a result of the elections, but he awaits the path forward, Iranian state media reported.

“It will take some time for things to settle down and for the atmosphere to become conducive to the mediators resuming their visits,” the foreign minister said. “We have to wait.”

Amid growing concerns about renewed attacks on Iran following Tuesday’s midterm elections in the United States, US forces have struck Iran’s Qeshm Island in what officials have reportedly described as a defensive measure.

In the first attack since June on Qeshm Island, which serves as the primary platform for Iran’s “asymmetric” naval power, according to analysts, the US strikes come as both sides continue to adopt military and diplomatic postures.

Mediation efforts led by Qatar are continuing in a bid to avert a return to all-out war, which began on February 28 when the US and Israel launched strikes across Iran, triggering the closure of the critical Strait of Hormuz, surging oil and gas prices and massive damage to military, civil and energy facilities around the Gulf.

Here’s what we know:

What happened in the attack on Qeshm Island?

Several explosions were heard on Qeshm Island late on Monday, as US media reported that the US military had carried out what officials called “defensive strikes” in the Strait of Hormuz.

The blasts came in rapid succession, according to Iran’s state-owned IRNA news agency. Witnesses told the agency they saw two planes flying over the island, located off Iran’s southern coast along the waterway.

According to The Wall Street Journal, which quoted an unnamed official, the strikes on Monday night appeared limited and were not a resumption of a major operation.

The Associated Press news agency also quoted an unnamed US official as saying Washington had conducted the defensive strikes against “Iranians using surface-to-air missiles against US assets”.

The attack came after IRNA reported that the Iranian Revolutionary Guard Corps (IRGC) had destroyed a US MQ-9 drone east of the Strait of Hormuz.

The US first struck a critical desalination plant on Qeshm Island on March 7 – one week into the war. The strike, which Tehran branded a “flagrant crime” against civilians, cut off freshwater supplies to 30 surrounding villages.

But isn’t diplomacy ongoing?

It is, but it is fragile, and mixed messages are coming from both sides.

Qatari mediators have been engaged in indirect talks with Iranian officials in recent days. They have passed messages between the two sides, but the talks appeared to come to an end on Monday with no news of a breakthrough.

An official briefed on the talks told the Reuters news agency that Iran’s delegation had departed from Doha on Sunday, but that a draft proposal was still being circulated, without elaborating on the content.

Qatari mediators travelled to Tehran on Monday night for talks with Iranian Foreign Minister Abbas Araghchi regarding a version of a draft US-Iran deal which has been under negotiation for the past eight days, an official told Reuters.

Araghchi told IRNA on Monday: “Consultations through mediators are very intensive. We have presented our conditions and proposals, and everything depends on the political rationality of Washington.”

Ministry spokesperson Esmaeil Baghaei also told a news conference on Monday that the “ball” was in the US’s court as Iran’s demands were “clear and logical”.

He said the plan Iran submitted in September to end the war remained the focus of talks, but that the proposal could be shortened and implemented in “two days”, including reopening the Strait of Hormuz and returning to talks about Iran’s nuclear programme.

On Monday, Iranian President Masoud Pezeshkian also said Supreme Leader Ayatollah Mojtaba Khamenei had given the government “certain authorities” over talks with the US, local media reported.

The president added that Tehran would look to resolve the conflict through dialogue.

Khamenei’s apparent approval of diplomacy marks a change since the breakdown of the June memorandum of understanding, which allowed a brief ceasefire and peace negotiations, when the supreme leader said the US could not be trusted.

For the US side, Vice President JD Vance also told reporters on Monday that he was hopeful for a diplomatic solution – just hours before the strikes on Qeshm Island.

“The president and I both feel pretty good about the prospects for potentially coming to a negotiated settlement,” Vance said. “We’ve certainly made some progress. We’ll see if we can make some more.”

Parliament Speaker Mohammad Bagher Ghalibaf reiterated on Tuesday that Iran’s response to any US “miscalculation”, such as launching strikes, would be unpredictable.

“The enemy seeks to force the Iranian nation into submission through threats and military action, but they are sorely mistaken; Iran will not submit,” he said.

What has Trump said about diplomacy?

Oil prices dropped by more than 7 percent on Monday. In response, Trump wrote on his Truth Social account that people believe the war with Iran will not resume as mediation efforts continue.

“Iran wants a settlement, as soon as possible. It could happen!” Trump wrote.

He told media at the Lincoln Memorial Reflecting Pool in Washington, DC, that it looked like efforts were “coming together very nicely”.

“That’s why I guess the oil prices dropped. People found out about it.”

However, Trump also told the US media outlet Axios before his post on Truth Social that he was “in no rush” to decide whether to resume strikes on Iran.

“One way or the other, we will do something, but there is no rush. We crippled them financially. They have no money, no gasoline, and their people are getting very tired of it,” Trump told Axios in an interview.

What happens next?

The US midterm elections are being viewed as the inflexion point for Trump’s decision on what path he takes next.

The president has suggested several times that he could attack Iran following the vote and told the Right Side Broadcasting Network (RSBN) on Sunday that the conflict would end “very soon one way or the other”, adding that Tehran would either “make a deal, or we’ll just end it”.

Observers say the US will likely renew strikes on Iran’s nuclear facilities if they do resume.

In particular, this could include Iran’s Pickaxe Mountain, a highly fortified site that contains two tunnel complexes buried deep underground, and which Trump told US outlet Newsmax last month could be a target. He said the US “may have to go there. We’ll take a shot at that one. We’ll knock it out fast.”

The joint statement comes as US President Donald Trump seeks a new meeting with North Korean leader Kim Jong Un.

The United States, South Korea and Japan have reiterated their longstanding call for North Korea to give up its nuclear weapons, a move  Pyongyang has repeatedly ruled out.

The three countries addressed the issue on the sidelines of the Group of 20 (G20) meeting in the US city of Atlanta on Thursday, with their top diplomats reaffirming their “resolute commitment to the complete denuclearisation” of North Korea, according to a readout by the US Department of State.

US Secretary of State Marco Rubio, South Korean Foreign Minister Cho Hyun and Japanese Foreign Minister Toshimitsu Motegi also pledged the “full implementation” of United Nations Security Council resolutions, including a ban on supporting revenue for North Korea’s nuclear and ballistic missile programmes.

The statement comes despite repeated overtures to North Korea by US President Donald Trump, who held a series of historic summits with its leader, Kim Jong Un, during his first term in office and has continued to call Kim a “friend”.

Last year, Trump bucked a long-held US policy by conceding that North Korea was already “sort of a nuclear power”.

More recently, he has played down concerns about North Korea’s nuclear programme and expressed a desire to meet Kim again. Speculation is mounting that the two leaders could reconnect at next month’s APEC summit in China, which Trump is due to attend.

Analysts and South Korea’s spy agency say Kim may have conveyed Pyongyang’s position on potential talks with Trump to Beijing during a recent visit to the Chinese border city of Dandong.

South Korea’s dovish President Lee Jae Myung – who has repeatedly offered Pyongyang talks without preconditions – suggested in September that Washington seek a freeze, rather than the immediate elimination, of the North’s nuclear programme in return for sanctions relief.

Critics have said such an approach risks tacitly accepting North Korea as a nuclear-armed state while allowing Pyongyang to win sanctions relief without giving up its arsenal.

Despite long-running UN sanctions, North Korea, which is backed by Russia and China, has enshrined its status as a nuclear-armed state in law. Pyongyang’s government has declared its atomic arsenal to be permanent and irreversible.

Pyongyang denounced a joint statement on Saturday by a group of nations monitoring sanctions implementation against it, pledging that “the stereotyped sanctions racket of the US and the West can neither influence the position of the DPRK (North Korea) as a nuclear weapons state.”

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.

Latest missile launch appears to be a show of force since South Korea’s hypersonic missile test-fire, Seoul says.

North Korea has fired multiple ballistic missiles towards the sea off its east coast, South Korea’s military says.

South Korea’s Joint Chiefs of Staff (JCS) said one of the missiles flew more than 900km (559 miles) from the Pyongyang area on Monday. The joint chiefs did not specify how many missiles were detected.

Japan’s coastguard said on Monday that North Korea had fired two unidentified projectiles, believed to be ballistic missiles, which appeared to have already fallen.

South Korea’s presidential office said that Pyongyang’s repeated missile launches violate United Nations Security Council resolutions, urging an immediate stop.

Monday’s missile launch adds to heightened tensions on the Korean Peninsula, as both countries have been conducting weapons tests.

Escalating tensions

JCS spokesperson Jang Do-young said the latest missile launch appears to be a show of force since South Korea’s hypersonic missile test-fire.

On Thursday, South Korean President Lee Jae Myung oversaw the country’s first test-firing of a hypersonic missile, a rare public showcasing of a missile test by a South Korean president.

Lee’s office said the hypersonic weapon, once fully developed, would enhance South Korea’s ability to strike key targets by surprise in the “Korean Peninsula theatre of operations”.

On October 3, North Korea also tested a hypersonic intermediate-range missile designed to evade missile defences in South Korea and Japan.

Last week, Seoul demanded an apology after a landmine blast wounded three soldiers in the Demilitarized Zone between South and North Korea. A joint South Korean-UN investigation concluded that two landmines were planted by North Korean forces about a year ago. Pyongyang dismissed the claim and accused South Korea of provocation.

Prior to the border mine blast, Seoul said it was conducting “preliminary coordination efforts” to facilitate dialogue between Pyongyang and Washington.

Lee pledged to reopen dialogue with North Korea in his first speech after taking office in 2025.

North Korean leader Kim Jong Un continues to flaunt his nuclear weapons programme, while rejecting US and South Korean offers to resume stalled diplomacy.

Talks between Kim and US President Donald Trump abruptly ended in 2019. Kim Jong Un’s government continues to demand that Washington abandon its “hostile” policy towards Pyongyang and drop demands for North Korea’s denuclearisation as a condition for talks.
