'Sea of Oman will become your graveyard': Iran hardliner warns US as Israel readies for renewed strikes

Tehran's Expediency Council member Mohsen Rezaei says US naval blockade amounts to 'act of war', as Israeli media reports military on high alert for fresh hostilities

A senior Iranian official has warned the United States to lift its naval blockade of Iranian ports, cautioning that the Sea of Oman could turn into a "graveyard" for American forces if tensions escalate further.

Mohsen Rezaei, a member of Tehran's Expediency Council and former commander of the Islamic Revolutionary Guard Corps, made the remarks during an interview with state television on Monday morning. He described the US blockade, first imposed on April 13, as an "act of war" and said Iran's military was fully prepared for additional confrontation.

"We advise the US military to end the siege before the Sea of Oman becomes your graveyard," Rezaei said. "The longer they prolong the naval blockade of Iran, the greater the damage to countries around the world will be."

Israeli military on high alert

The warning came as Israeli media reported that the Israel Defense Forces have been placed on high alert amid preparations for possible renewed hostilities with Iran. Public broadcaster Kan, citing an unnamed security official, said Israel would join any fresh American strikes and could target Iranian energy infrastructure.

The report followed a phone call lasting more than 30 minutes between US President Donald Trump and Israeli Prime Minister Benjamin Netanyahu on Sunday. Trump has maintained that the blockade will continue until Iran agrees to a peace deal on US terms.

Meanwhile, dozens of US cargo planes carrying ammunition from military bases in Germany landed in Tel Aviv over the past 24 hours, according to Channel 13. The broadcaster said the shipments were part of preparations for a possible resumption of military operations against Iran.

UAE nuclear plant attack draws Indian concern

India on Monday expressed concern over the reported drone attack targeting the Barakah Nuclear Power Plant in the United Arab Emirates, calling it a "dangerous escalation" and urging all sides to exercise restraint.

The UAE has blamed Iran or one of its proxies for the strike, which caused a fire just outside the nuclear facility. Officials confirmed there were no injuries or radiation alerts, with the emirate's nuclear regulator stating there was no radioactive leak or risk to the public.

In a statement, the Ministry of External Affairs said the attack was unacceptable and stressed the need for an immediate return to dialogue and diplomacy amid rising regional tensions.

Oil prices surge as diplomacy stalls

Oil prices rose another 2 per cent on Monday, with Brent crude trading at $110.72 a barrel – more than 50 per cent higher than before the US-Israel war on Iran began. Trump's warning that the "clock is ticking" for a peace deal has added to market jitters.

Iran signalled tighter control over the Strait of Hormuz earlier in the day, with authorities saying all vessels passing through the crucial shipping route must now coordinate with Iranian military forces. Reports from Hormuz Island said IRGC naval units have claimed authority over the strait, warning that military vessels would not be allowed to pass.

According to Iran's Foreign Ministry spokesperson, talks continue through Pakistan as a mediator, with both Tehran and Washington sending comments on a recent Iranian proposal. But Rezaei' rhetoric suggested any diplomatic breakthrough remains distant.

Strikes continue in Lebanon, Gaza

The Israeli military said it struck more than 30 Hezbollah infrastructure targets in southern Lebanon on Monday, including a weapons warehouse and observation posts. In Gaza, local reports said three Palestinians were killed when Israeli forces struck a kitchen providing meals to displaced people.

At least 871 people have been killed since the so-called "ceasefire" began last October, according to the Palestinian Health Ministry in Gaza.

Iran Vows No Ceasefire Until Compensation, Sanctions Relief Secured

Tehran sets conditions for ending hostilities, demanding a full lifting of economic sanctions and binding guarantees from the United States against future interference.

Iran has firmly stated that the ongoing military conflict will not cease until its demands are met, including financial compensation for losses incurred during the 25-day-long war with Israel and the United States. Senior Iranian officials on Tuesday laid out a hardline stance, dismissing any prospect of a ceasefire without concrete diplomatic and economic assurances.

Tehran Lays Out Conditions

Mohsen Rezaei, a senior adviser to Supreme Leader Mojtaba Khamenei, declared in a televised address that Iran’s position is non-negotiable. He asserted that all economic sanctions must be lifted, and the US must provide a "firm guarantee" against any future interference in Iran’s affairs. Rezaei added that Iranian military operations continue with full force, with the leadership maintaining a firm grip on the situation under the new Supreme Leader. Parliament Speaker Mohammad Bagher Ghalibaf echoed the sentiment, noting that the public is demanding strict punishment for those responsible for the attacks against the nation.

Rezaei Blames Israel for Prolonged War

Rezaei claimed that the conflict could have concluded within a week had it not been for the actions of Israel. According to the senior official, the United States was prepared to agree to a ceasefire and de-escalate the situation. However, he alleged that Israeli Prime Minister Benjamin Netanyahu insisted on continuing the military campaign, thereby prolonging the war. Rezaei further stated that by the 15th day of the conflict, even Washington had come to realize there was no clear path to victory in the region.

Conflicting Accounts on US-Iran Talks

The political landscape is further complicated by conflicting reports regarding potential negotiations. US President Donald Trump claimed on his social media platform that talks had been held with Iran, leading him to delay strikes on Iranian power plants for five days. Conversely, Iranian officials have categorically denied that any direct talks have occurred. Speaker Ghalibaf labelled the claims as “fake news” designed to manipulate financial and oil markets. However, a senior Iranian official provided a nuanced account to the BBC, confirming that "points from the US" were received through mediators and were currently under review.

Market Volatility Amid Diplomatic Confusion

The mixed signals have sent shockwaves through global financial markets. Brent crude oil prices briefly jumped back above $100 per barrel on Tuesday after a dramatic 10% plunge the previous day, reflecting the uncertainty. The initial drop was triggered by Trump’s statements about delaying strikes, while the subsequent rise followed Iran’s firm rejection of the talks and its reaffirmation of military readiness. Asian stock markets, particularly in South Korea, showed a slight recovery from Monday’s 17-year low for the won, as investors cautiously priced in hopes of de-escalation.

Regional Military Actions Escalate

The ground and aerial situation remains volatile. Israel confirmed a new wave of missiles was launched from Iran towards its territory, with air defence systems actively working to intercept them. Meanwhile, Iran released footage of missiles at an underground facility, a display of its military capabilities. In a separate development, the Israeli military reportedly destroyed the al-Qasmiya Bridge over Lebanon’s Litani River, a move that effectively cuts off southern Lebanon from the north. The closure of the Strait of Hormuz to most maritime traffic continues to strain global supply chains, prompting South Korea to cancel high-level diplomatic trips and Japan to announce the release of oil stockpiles.

What Next: A Diplomatic Crossroads

The coming days are critical as the international community watches for any official confirmation of a backchannel meeting. Reports suggest US Vice President JD Vance and other American officials may meet with their Iranian counterparts in Islamabad this week, though the White House has declined to confirm this, stating the situation remains fluid. For now, Iran’s official stance remains rigid, demanding a resolution on its terms, while the United States and Israel weigh their next military or diplomatic moves. The global economy remains on edge, bracing for either a de-escalation or a further intensification of the conflict.
