Pro-establishment voices on Persian-language social media claim a recent earthquake in Iran’s Semnan Province was actually a covert nuclear test, with ultra-hardliners calling for Iran to pursue nuclear deterrence capabilities.
“It seems that there was no earthquake but a nuclear test in Semnan two nights ago … Now [can you imagine] what would happen if that explosion occurred on the ground in Israel?” one of them asked.
Despite the recorded depth of the seismic activity, many Persian-language social media users on major platforms like X and Telegram, as well as domestic platforms such as Eitaa, are calling the tremor proof of an Iranian nuclear test.
“An Iranian bomb is our inalienable right,” another tweet with the hashtag #بازدارندگی_اتمی (nuclear deterrence), which many others have been extensively using in recent days, read.
“Our people have the right to enjoy nuclear deterrence. Have the courage to take the historical decision [to go nuclear],” a tweetaddressed to the authorities that claimed the country’s nuclear program has so far cost $2,000 billion to the nation declared.

“It’s true that the decision to build a nuclear weapon and whether it is religiously banned or not lies with the Leader ... When there is talk of building nuclear weapons, it is for a balance of power and deterrence, not actual use,” another netizen tweeted arguing that Pakistan developed nuclear capabilities only after India built its bomb “to deter threats and [create] balance.”
The tweet referred to the Iranian state's official argument, based on Supreme Leader Ali Khamenei's often disputed nuclear fatwa, that Iran has never sought nuclear weapons because he has religiously banned all weapons of mass destruction, including nuclear bombs. Many experts have also disputed the legitimacy of this fatwa, given Iran's rapid advancement of its nuclear program raising concerns about its intentions.
Other individuals on X arguedthat the religious ban could and must be lifted to allow Iran to revise its nuclear doctrine.
Many other netizens, however, have refuted the claim that the tremor Saturday was the result of an underground nuclear test, pointing out that a nuclear test could not have been carried out at the depth recorded by seismological organizations.
Ultra-hardliners who fervently circulated the rumor Sunday on Telegram channels and X appear to have taken their inspiration from several tweets in English that suggested Iran may have conducted a nuclear test Saturday.
These, including a tweet by DD Geopolitics and ConflictX, based their argument on the false premise that an Armenian seismology station had picked up the tremor first and claimed that a comparison between typical earthquake vibrations and nuclear tests suggested the event resembled a nuclear test.
Several Armenian news outlets including News.am that reported the earthquake, however, had quoted Tehran University’s Geophysics Institute as their source, not an Armenian seismological station as these and similar tweets claimed.
In another tweet, DD Geopolitics displayed a graph that compared earthquake and explosion pairs, suggesting that real earthquakes were followed by several lesser tremors (aftershocks). In contrast, nuke tests by Pakistan, India, North Korea, and Soviet Union did not.
DD Geopolitics is an online media outlet run by an allegedly pro-Russian former US Navy veteran, Sarah Bills, who has been accused of running social media accounts “notorious for spreading disinformation about the war [in Ukraine]”.
“The report of a nuclear test in the desert in Semnan [Province] is not true. But it is noteworthy that many Iranians paid attention to it and in comparison, many welcomed it more than before, Mostafa Najafi, Tehran-based Ph.D. candidate in international relations at Toronto Metropolitan University tweeted.
“The idea and demand for building a nuclear weapon has grown recently following the recent increase in the level and range of threats against Iran, especially from countries with nuclear weapons, and it is being spoken of more often in official and unofficial circles,” Najafi wrote.
Iran’s foreign minister warned Israel on Tuesday not to test Tehran’s resolve, stating that while Iran won’t act hastily, it also won’t hesitate to deliver a strong retaliation if attacked.
Abbas Araghchi spoke at a gathering marking the October 7 anniversary of the Hamas attack on Israel, where Iranian officials lauded the assault as a major achievement by the so-called "Resistance axis," a network of regional militant groups backed by Iran.
"We recommend the Zionist regime (Israel) not to test the resolve of the Islamic Republic. If any attack against our country takes place, our response will be more powerful," Araghchi said in a televised speech.
After a series of devastating Israeli operations against Iran’s main proxy group, the Lebanese Hezbollah and the killing of its leader Hassan Nasrallah, the Islamic Republic launched a large missile barrage against Israel on October 1. This was the second Iranian missile attack since April, but like the earlier operation, it inflicted little damage. The Israeli government immediately vowed a punishing retaliation, but so far, no attack has taken place.
Echoing Supreme Leader Ali Khamenei, Araghchi reaffirmed that Tehran “stands fully behind the Resistance, with its full strength and support.”
However, beyond its stockpile of hundreds of ballistic missiles, Iran has limited military capacity to effectively challenge Israel, which boasts far more advanced military and weapons systems. Despite launching around 300 ballistic missiles, along with drones and cruise missiles, in two large-scale attacks, Iran has achieved little success. Most of the projectiles have been intercepted by Israeli and allied anti-air defenses, rendering the assaults largely ineffective.
However, Araghchi warned that “Any attack by the Zionist regime [Israel] on Iran's infrastructure will be met with a stronger response.” He also stated “Our enemies know which targets within the Zionist regime are within our reach. They have witnessed firsthand the power of our missiles.”
The scope and scale of a potential Israeli attack on Iran are subjects of intense debate among military experts and analysts. While strikes on some of Iran’s nuclear facilities remain a possibility, most experts believe Israel would more likely focus on key energy, economic, and military targets.
Media outlets in Tehran have pounced on a fresh push by Iran's exiled prince to deepen ties with Israel and advocate for the fall of the Islamic Republic by highlighting differences between his father and the Jewish state.
Scrutiny of the long-overlooked historical chapter was revived when former Israeli Prime Minister Naftali Bennett last week urged Israel to act decisively against Iran, saying the Islamic Republic’s proxies Hamas and Hezbollah have been weakened.
"Israel now has its greatest opportunity in the last 50 years to change the face of the Middle East," Bennett posted on X on October 2, emphasizing the need for action following Iran’s missile attack on Israel the previous day.
Bennett's comments appear to reference events extending back to the Pahlavi era, coinciding with the 50-year anniversary of the 1973 Yom Kippur War.
Iranian dailies Entekhab and Shahr-e khabar said Bennett was highlighting a rift between Israel and Iran's leadership even prior to the 1979 revolution.
Iran’s historical relationship with Israel
Under Shah Mohammad Reza Pahlavi, Iran maintained close ties with Israel, becoming the second Muslim-majority nation to recognize the Jewish state.
Despite opposition from some political figures, relations between Iran and Israel were strengthened through arms deals and security cooperation, with Israel providing military assistance in exchange for Iranian oil.
The Islamic Republic largely upended that relationship, becoming one of Israel's most vocal adversaries.
Iran's leadership, particularly Supreme Leader Ali Khamenei, has repeatedly vowed Israel’s destruction, with state-sponsored events promoting Holocaust denial further inflaming tensions.
However the article on Entekhab's website on Monday noted that ties between Iran and Israel began to deteriorate after the 1973 Yom Kippur War in October 1973.
“The Shah sought more independence in foreign policy, diversifying arms purchases and pursuing stronger ties with other global powers, including the Soviet Union," Entekhab wrote on Monday.
"During the war, the Shah allowed Soviet planes to pass through Iranian airspace to deliver military supplies to Egypt, and Iran provided financial and oil support to Egypt. This further strained relations with Israel, leading to a gradual distancing between the two nations, which culminated in the complete severance of ties after the 1979 Iranian Revolution,” it added.
The Shah maintained good relations with then-Egyptian President Anwar Sadat and on a few occasion did criticize Israel while even more strongly criticizing the Palestinians. However, he was a Western ally and continued cooperation with Israel.
Reza Pahlavi’s advocacy
Reza Pahlavi, the exiled son of the Shah, presents a viewpoint that starkly contrasts with the narrative put forth by Entekhab and others.
He has actively called for “regime change” in Iran while advocating for renewed ties with Israel. In April 2023, Pahlavi traveled to Israel “to deliver a message of friendship from the Iranian people.” He publicly prayed for peace between Israel and Iran during a visit to the Western Wall in Jerusalem.
Pahlavi expressed hopes that the two nations can one day resume their historical friendship.
He tweeted from the Western Wall, referencing Cyrus the Great's liberation of the Jewish people: “It is with profound awe that I visit the Western Wall of that Temple and pray for the day when the good people of Iran and Israel can renew our historic friendship.”
In an interview with Fox News on Sunday, Pahlavi said, “An Iranian regime change would mean an end to many global problems.” He emphasized that a change would alleviate many global problems, highlighting the detrimental impact of the current leadership on Iran’s economy and stability.
"The nuclear threat, the proliferation of this ideology, period, the end of this regime would mean an end to all these problems," he said.
Twenty-two female political and ideological prisoners in Tehran’s Evin Prison have released an open letter demanding an immediate halt to the sexual harassment of inmates during body searches.
"We, a group of female political and ideological prisoners in Evin prison, are demanding accountability for the unconventional body searches and sexual harassment of several inmates during these inspections. If the authorities do not respond, we will resort to protest actions," their letter published on political prisoner Gholrokh Iiraee’s X account on Sunday said.
Recent reports have shed light on incidents of sexual assault and abuse within Iran’s prison system.
"These body inspections have become an excuse to sexually harass prisoners," said journalist and human rights activist, Reza Akvanian, commenting on the situation in an interview with Iran International.
While technology exists to conduct non-invasive scans, Akvanian said, Iranian prisons continue to allow invasive procedures that can result in sexual harassment. Akvanian doubted the Islamic Republic’s judiciary's willingness to address these violations, citing past neglect and the stepped-up sentences faced by activists who report such abuses.
Nobel Peace Prize laureate, Narges Mohammadi, imprisoned in Evin and one of the signatories of the letter, faced new charges earlier this yearafter exposing incidents of sexual harassment against detained women.
A March 2024 report from the UN’s Independent Fact-Finding Mission (FFM) on Iran confirmed instances of sexual violence, including gang rape and forced nudity inflicted upon those detained during Iran’s nationwide Women, Life, Freedom protests following Mahsa Amini's death in police custody in 2022.
“To extract confessions, punish and humiliate detained women, girls, men and boys, security officers subjected them to sexual and gender-based violence, including rape, gang rape, rape with an object, and forced nudity, as well as beatings, flogging and burning, the use of electric shocks, suspension, and stress positions, in acts amounting to torture,” the FMM said in their report.
Last year Human Rights Watch and Amnesty Internationalreleased reports detailing sexual assault by agents of the IRGC, Basij, Ministry of Intelligence, and various police departments against women, men, and children during the protests following Amini's death.
Iranian officials not only continued to threaten Israel on Monday but also glorified the October 7 Hamas attack as the anniversary passed without the anticipated Israeli retaliation.
Vice President Mohammad Reza Aref, in an interview with ISNA, said the threats against Iran after last week's missile barrage were "a joke" as Israel bided its time to respond.
Iranian military leaders spoke defiantly as the country prepared for certain retaliation. Abdolrahim Mousavi, Commander-in-Chief of Iran’s Army, stated that Lebanese Hezbollah, Iran's largest proxy, had inflicted “severe” blows on Israel, and further violence would lead to “harsher” Iranian responses. "If the Zionists commit a crime in response to the reply we gave them, they will undoubtedly receive a stronger and more destructive response," Mousavi said.
They did not acknowledge that Iran's response to the killing of Iran-backed Hamas leader Ismail Haniyeh was only carried out two months later, and on the back of the killing of Hezbollah leader, Hassan Nasrallah.
Meanwhile, Israel's Kan 11 reported that the United States had offered Israel a “compensation package” if it refrained from attacking specific Iranian targets. This package reportedly included comprehensive diplomatic protection and a weapons package, according to American officials involved in the negotiations.
As Israel mourned the one-year-anniversary of the October 7 atrocities, in which 251 people were taken hostage to Gaza and 1,100 mostly civilians were killed, the official X account of Supreme Leader Ali Khamenei in Hebrew stated, "The Al-Aqsa Storm operation", another name for the October 7 attack, "set the Zionist regime back by 70 years."
With the country in mourning, many Israelis felt the timing of a retaliation would be inappropriate on the day when ceremonies around the country focused on those lost and the people still held in captivity.
In an interview with Fox News on Sunday, Israeli Defense Minister Yoav Gallant stated that “everything is on the table” and that Israel would respond to the unprecedented Iranian attack "in the manner of our choosing, and at the time and place of our choosing."
Expectations of an Israeli strike grew on Sunday night as Iran locked down flight paths on the eve of the one-year anniversary of the Hamas attack, but Iran’s Civil Aviation Organization lifted flight restrictions late Sunday night.
Iran's First Vice President said that "no threat [of retaliation] can make us retreat from our plans and actions; we will continue our path firmly", as Iran's proxies around Israel continue to send missiles to the Jewish state.
Adding to the rhetoric, Iran’s National Security Commission also reviewed the country's preparedness for possible Israeli retaliation. Ebrahim Rezaei, the commission's spokesperson, noted that key Iranian military and security institutions, including the IRGC and the Ministry of Defense, presented reports on their readiness to face threats.
As tensions continue to mount, both sides seem poised for a potential confrontation amid a bitter psychological war. While Iran maintains its threats and displays of defiance, Israel's promised response remains to be seen, leaving the region on edge, awaiting the next move.
Informed sources have told Iran International that even the family of Quds Force commander Esmail Qaani remains unaware of his current status, as the IRGC has yet to release any official statement regarding his fate.
Reports emerged on Saturday that Qaani might have been in Beirut following the death of Hezbollah leader Hassan Nasrallah and continued Israeli air strikes on position of the Iran-backed group. No one has heard about Qaani since October four and there are speculations that he might have been killed or injured in Israeli air strikes.
A targeted airstrike, which aimed to eliminate Hashem Safieddine, a senior Hezbollah leader and potential successor to Hassan Nasrallah, has raised speculation about Qaani’s possible presence at the bombed location. The New York Times, citing three unnamed Iranian officials, reported that Qaani had traveled to Lebanon last week to meet with Hezbollah officials in an effort to strengthen the group.
Reuters also reported on Sunday that according to Iranian officials Qaani has not been heard from since Friday. Senior Hezbollah official Mahmoud Qmati told Reuters: "I have no information, we are also searching for the truth of this matter."
While Israel’s Channel 12 suggested that Qaani might have been injured in the attack, there has been no confirmation from Iranian authorities. A Lebanese security source told Reuters that communication with Safieddine has been cut off since the strike, further fueling concerns about high-level casualties among Hezbollah leadership.
Qaani’s absence from key government ceremonies in Iran, including an event where Supreme Leader Ali Khamenei awarded a military badge to IRGC Aerospace Forces commander Amirali Hajizadeh, has only added to the growing uncertainty. Iran has not released any recent photos or videos of Qaani.
Meanwhile, in a sign of heightened tensions and amid fear of possible Israeli retaliation for last week attack, Iran's Civil Aviation Organization has canceled all flights from Sunday evening to Monday morning, citing "operational limitations." This follows a pattern seen in April when Iranian flights were suspended for nearly 48 hours after Iran launched missile attacks on Israeli positions.
At the same time, Israeli Defense Minister Yoav Gallant responded to recent Iranian actions with a stern warning. "Whoever thinks that a mere attempt to harm us will deter us from taking action should take a look at Gaza and Beirut," Gallant stated, referring to the October 1 Iranian missile strike on two Israeli air force bases. Gallant emphasized that no Israeli aircraft or squadrons were damaged in the strike.
As tensions escalate, both sides are preparing for potential further confrontations, with Iran threatening reciprocal action if Israel launches any new attacks. Iran closed its airspace Sunday night until Monday morning.
