CAIRO – In a bold move, Iran has reiterated its intention to limit the passage of ships through the vital Strait of Hormuz, contingent upon the continuation of the U.S. blockade of Iranian ports. This development occurs as mediators hasten to arrange further discussions before the truce reaches its expiration later this week.

Iranian parliamentary Speaker Mohammed Bagher Qalibaf emphasized in a televised address that Tehran remains committed to threatening commercial vessels navigating this crucial maritime corridor. This comes in the wake of incidents on Saturday where Iran fired upon ships attempting to pass through.

“It is unthinkable for others to traverse the Strait of Hormuz when we are denied the same access,” stated Qalibaf, who leads Iran’s negotiations with the United States.

The Iranian navy has issued warnings to ships about passing through the strait, a critical juncture for approximately 20% of global oil trade. Following a brief spike in transit attempts on Saturday, vessels in the Persian Gulf have maintained their positions, cautious after two India-flagged ships were targeted and forced to retreat mid-passage.

The withdrawal of these ships has reverted the strait to its tense status prior to the ceasefire, potentially exacerbating the global energy crisis and edging the involved parties closer to renewed hostilities as the conflict persists into its eighth week.

The tenuous ceasefire between the U.S. and Iran is set to lapse by Wednesday. On Saturday, Iran announced it had received new proposals from the United States, while Pakistani mediators are actively working to facilitate another round of direct negotiations.

For Iran, the strait’s closure — imposed after the U.S. and Israel launched the war on Feb. 28 during talks over Tehran’s nuclear program — is perhaps its most powerful weapon, threatening the world economy and inflicting political pain on President Donald Trump. For the United States, the blockade squeezes Iran’s already weakened economy and pressures its government by denying it long-term cash flow.

Though the ceasefire has held, the standoff in the strait threatens to plunge the region back into a war that has killed at least 3,000 people in Iran, more than 2,290 in Lebanon, 23 in Israel and more than a dozen in Gulf Arab states. Thirteen U.S. service members have been killed.

Reopening hopes sink as ships come under fire

Iran announced the strait’s reopening to commercial vessels after a 10-day truce between Israel and the Iranian-backed Hezbollah militant group in Lebanon took hold on Friday. But after Trump said the U.S. blockade of Iran’s ports “will remain in full force” until Tehran reaches a deal with the United States, Iran said it would continue enforcing its restrictions on ships attempting to pass.

Revolutionary Guard gunboats opened fire on a tanker and a projectile hit a container vessel, damaging some containers, the British military’s United Kingdom Maritime Trade Operations center said. India’s Foreign Ministry said it summoned Iran’s ambassador over the “serious incident” of firing on two India-flagged merchant ships, especially after Iran earlier let several India-bound ships through.

“Americans are risking the international community, risking the global economy through these, I can say, miscalculations,” Iranian Deputy Foreign Minister Saeed Khatibzadeh told The Associated Press, adding that the U.S. is “risking the whole ceasefire package.”

Iran’s Supreme National Security Council issued a statement calling the blockade a violation of the ceasefire and said Iran would prevent “any conditional and limited reopening” of the strait. The council has recently acted as Iran’s de facto top decision-making body.

Since most supplies to U.S. military bases in the Gulf region come through the strait, “Iran is determined to maintain oversight and control over traffic through the strait until the war fully ends,” the council said. That means Iran-designated routes, payment of fees and issuance of transit certificates.

Pakistan pushes for progress toward a new deal

The renewed standoff over the strait came hours after Pakistani Foreign Minister Ishaq Dar said his country was working to “bridge” differences between the U.S. and Iran. Pakistan is expected to host a second round of negotiations early next week.

Iran’s Supreme National Security Council said “new proposals” from the U.S. had been put forward during a visit to Iran by Pakistan’s army chief and were being reviewed.

But Khatibzadeh said the Iranians were not ready for a new round of face-to-face talks because the Americans “have not abandoned their maximalist position.”

He also said Iran will not hand over its stock of 970 pounds (440 kilograms) of enriched uranium to the United States, calling the idea “a nonstarter.” Khatibzadeh did not address other proposals for the enriched uranium, saying only that “we are ready to address any concerns.”

Trump said Saturday that Iran “got a little cute” but that “very good” conversations were happening, and more information would come by day’s end. “They can’t blackmail us,” he added.
