Iran's new Supreme Leader Mojtaba Khamenei has vowed inevitable revenge for the assassination of his father, Ali Khamenei, and family members in US-Israeli strikes, declaring retaliation a national demand that will occur "soon" regardless of his own survival.

In a written statement released on Saturday, following the conclusion of week-long funeral ceremonies in Mashhad, Mojtaba promised that the "criminal and disgraced killers," whose names are documented, would not die peacefully. The new leader, who has not appeared publicly since sustaining injuries in the February 28 attacks, emphasized that vengeance is a "divine mission" for the Iranian nation.

“Revenge for Iran’s martyred leader is the will of our people, and it must certainly be carried out," Mojtaba wrote. "These criminals, all of whom are fully identified, from the most senior to the most junior, will take to their graves the dream of dying peacefully in their beds.”

President Donald Trump responded with an explicit threat on Truth Social, stating that 1,000 missiles are "locked and loaded" and aimed at Iran, with thousands more ready to follow if Tehran attempts to assassinate him. Trump ordered the US military to be prepared to "completely decimate and destroy all areas of Iran" for a one-year period should any attack on his life occur, citing intelligence regarding hardline factions' aspirations.

While US officials noted no evidence of a unified, specific assassination plot currently in motion, the exchange of threats has severely strained relations just weeks after a temporary peace memorandum was signed.

Meanwhile diplomatic talks in Oman regarding the Strait of Hormuz concluded without an agreement, as Iran rejected proposals for separate navigation routes and refused US demands to surrender its enriched uranium stockpile.

Iranian Foreign Minister Abbas Araghchi accused Washington of violating the interim deal by revoking oil waivers following Iranian attacks on commercial vessels, while the US insisted the ceasefire is effectively "over" due to these maritime hostilities.

With Iran maintaining that control of the strategic waterway rests exclusively with Tehran, the failure of these negotiations raises the risk of further military escalation in the Persian Gulf.

President Donald Trump on Friday, posted on Truth Social that the Islamic Republic of Iran has asked to continue "talks" and that the U.S. agreed, but he emphatically stated "the Cease Fire is OVER!" in no uncertain terms. Qatari mediators are reportedly in Iran for talks in coordination with the U.S. and Pakistan.

While Trump confirmed ongoing diplomatic engagement, he said the June ceasefire agreement is nullified following recent Iranian attacks on commercial shipping in the Strait of Hormuz. “The Islamic Republic of Iran has asked us to continue 'talks.' We have agreed to do so, but the United States has stated to them, in no uncertain terms, that the Cease Fire is OVER!” he wrote.

The "Cease Fire" Trump referred to was a 60-day Memorandum of Understanding (MOU) signed on June 17, 2026. This interim deal was intended to pause the U.S.-Israeli military campaign against Iran—which originally erupted on February 28, 2026—and restore the flow of international shipping.

However, the truce collapsed earlier this week when Iran attcked three Qatari and Saudi commercial tankers passing through the Strait of Hormuz earlier in the week. Iran blamed U.S. attempt to undermine the Persian nation's management of transit through the Strait.

The U.S. has reportedly given Iran until Saturday (July 11, 2026) to issue a formal, public statement. Washington is demanding that Tehran explicitly declare that the Strait of Hormuz is open to all international transit and pledge an immediate halt to all attacks on commercial vessels. U.S. officials have warned that if Iran continues to disrupt shipping or engage in hostile acts, the military will resume heavy strikes.

Compounding the geopolitical tension, Trump revealed during a phone interview with the New York Post on Friday, that he has prepared a severe military contingency plan in the event that Iran successfully targets him.

“I’ve been on their list for a long time. That’s what we’re dealing with… The only thing is, I’ve left instructions — if anything happens, to just literally bomb them at levels that they’ve never seen before,” Trump claimed.

Israel reportedly shared fresh intelligence with U.S. officials tracking specific Iranian plots against Trump. While Trump publicly downplayed the new intelligence in his interview, U.S. intelligence agencies have been monitoring a steady stream of threats, but are skeptical of Israel's intelligence and motives.

The rhetoric has reached a boiling point during the multiday mass funeral proceedings in Iran for former Supreme Leader Ayatollah Ali Khamenei, who was killed in the initial U.S.-Israeli strikes on February 28. At the state-sponsored viewings, massive banners calling for Trump's death were prominently displayed by the regime. Tehran has openly vowed vengeance against Trump ever since the 2020 strike that killed Quds Force Commander Qassem Soleimani.

Israel shared intelligence with the United States alleging that Iran was developing a new plan to assassinate President Donald Trump, a report that coincided with the resumption of hostilities and U.S. strikes on Iran following Iranian attacks on ships in the Strait of Hormuz.

While the White House pointed to Trump’s claims that he is Iran’s "number one target," many U.S. officials doubted the new intelligence, viewing it as potentially unvetted and part of a broader Israeli effort to influence Trump’s decision-making regarding further military action.

The U.S. had not independently verified the specific plot, though it noted a steady flow of general threats against Trump in recent weeks.

The intelligence sharing occurs amid strained relations between Trump and Benjamin Netanyahu. Netanyahu has opposed Trump’s diplomatic efforts with Iran, arguing for continued military operations to ensure Iran does not acquire nuclear weapons, whereas Trump has sought to end the conflict due to economic concerns.

Iran has long vowed to retaliate against Trump for the 2020 drone strike that killed top general Qasem Soleimani, and mourners at the funeral of slain Supreme Leader Ayatollah Ali Khamenei recently chanted slogans calling for Trump’s death. He was killed, along with some of his family members, by US and Israeli strikes at the start of the war on February 28.

Tensions have escalated significantly recently, with a previously agreed-upon 60-day ceasefire now described by Trump as "over" after Iran attacked multiple vessels in the Strait of Hormuz. In response, the U.S. launched strikes on dozens of sites across Iran, while Iranian forces retaliated with attacks on Kuwait, Jordan and Bahrain.
