U.S. President Donald Trump accused Iran of violating a recent ceasefire, announcing that American negotiators would travel to Pakistan for further talks. This development follows Iran's reversal on reopening the Strait of Hormuz, a critical waterway for global oil shipments. Iran's Islamic Revolutionary Guard Corps fired upon a commercial vessel attempting passage Saturday, according to maritime firm Lloyd's List, escalating tensions significantly.
The Islamic Revolutionary Guard Corps (IRGC) announced a clear reversal in Iran's position, stating the Strait of Hormuz would not return to its "previous state." This declaration came after the United States maintained its blockade on Iranian ports, which began April 14. Ships in the Persian Gulf, after a brief rise in transit attempts on Saturday, once again halted movement. Reports indicated vessels came under fire mid-passage and were forced to withdraw.
The United Kingdom Maritime Trade Operations agency (UKMTO) received a report of a tanker being fired upon by what it identified as two IRGC-linked gunboats. Tehran cited the US blockade of its ports as the primary reason for its decision. The Iranian military command called American actions "acts of piracy." It also labeled them "maritime theft." This statement was broadcast by Iranian state television IRIB.
Control of the waterway returned to its previous, tightly managed state. This situation will persist. It will last until the United States restores full freedom of navigation for Iranian vessels, the IRGC declared.
Iran's chief negotiator and Speaker of Parliament, Mohammad Bagher Ghalibaf, echoed the IRGC's stance. He stated it was "impossible for others to pass" the strategic strait without Iran’s consent. Ghalibaf called Washington’s blockade "ignorant" and "foolish," asserting Tehran would not permit transit if its own ships were blocked.
He acknowledged major differences remained in negotiations, despite some progress towards a deal. In Washington, President Trump maintained a firm posture. He described recent discussions as "very good." However, he insisted the US would not be "blackmailed" by Tehran's actions.
On Sunday, in a post on Truth Social, Trump accused Iran of violating the ceasefire agreement. He then confirmed American negotiators would head to Islamabad, Pakistan, on Monday. "We're offering a very fair and reasonable deal, and I hope they take it because, if they don't, the United States is going to knock out every single power plant, and every single bridge, in Iran," Trump wrote. This threat laid bare the high stakes.
International reactions quickly emerged. India summoned the Iranian ambassador in New Delhi, expressing deep concern. Two Indian-flagged ships reportedly came under fire in the strait, according to the Indian government.
Such incidents underscore the broader risks to global commerce and energy security. The strait is a chokepoint. Approximately a fifth of the world’s oil passes through it daily.
This standoff complicates efforts to end the wider US-Israel war on Iran. The Strait of Hormuz has again become a chaotic center of this conflict. Iranian Foreign Minister Abbas Araghchi had stated on Friday that the strait would be open for commercial vessels during the truce, which concludes on April 22.
This was to be "in line with the ceasefire in Lebanon," Araghchi told Al Jazeera. The ceasefire in Lebanon, a 10-day truce between Israel and the Lebanese armed group Hezbollah, remains fragile. Israel has conducted strikes despite the agreement.
Its forces have established a buffer zone, akin to Gaza's "yellow line." Hezbollah condemned the ceasefire agreement as "an insult to our country" and "a slippery slope with no end in sight." The Lebanon-based group stated, "A ceasefire means a complete cessation of all hostilities." They expressed distrust of their enemy. Resistance fighters, Hezbollah affirmed, would remain ready to respond to any violations. A ceasefire, they argued, cannot be unilateral.
Hezbollah represents Tehran’s most powerful regional ally. It forms a core pillar of the "axis of resistance," a network of armed groups across the Middle East aligned with Iran against Israel. This network includes Yemen's Houthis and various factions in Iraq.
Hezbollah joined the fighting after the Israeli army killed Iran's Supreme Leader Ayatollah Ali Khamenei on February 28 in strikes on Tehran. His son, Mojtaba Khamenei, has since been named his successor. Behind the diplomatic language lies a hardening of positions, particularly on Iran’s nuclear program.
This remains the biggest contention. Chief among these issues is Tehran’s nuclear enrichment capability. On Friday, Trump declared Washington would obtain Iran’s enriched uranium.
He called it "nuclear dust." He referred to the 440kg (970lbs) believed to be buried at sites hit by US strikes last year. "The USA will get all Nuclear 'Dust'," he reiterated on Truth Social. Speaking to Reuters news agency, Trump indicated the US would work with Iran "at a nice leisurely pace." They would "start excavating with big machinery" to recover the material. In a direct rebuke, Iran’s President Masoud Pezeshkian asserted Washington had no justification for depriving Iran of its nuclear rights. "Trump says Iran cannot make use of its nuclear rights, but doesn’t say for what crime.
Who is he to deprive a nation of its rights?" Pezeshkian asked, according to the Iranian Students’ News Agency. Here is what they are not telling you: the US position ignores Iran's long-held insistence on civilian nuclear development. Israel and the United States have consistently accused Iran of enriching uranium to develop nuclear weapons.
Iran, however, maintains its nuclear program serves civilian purposes. It states it has honored its commitments under the Nuclear Non-Proliferation Treaty. Tulsi Gabbard, the director of US National Intelligence, testified to Congress in March 2025.
She stated the US "continues to assess that Iran is not building a nuclear weapon and Supreme Leader [Ayatollah Ali] Khamenei has not authorised the nuclear weapons programme he suspended in 2003." This testimony contrasts sharply with the public rhetoric. Abas Aslani, a senior fellow at the Centre for Middle East Strategic Studies in Tehran, observed the two sides are "engaging in war rhetoric ahead of any possible escalation and military conflict." Aslani told Al Jazeera, "It seems that they are pressuring each other to win concessions – and we are not there yet." He noted speculations about possible limited US strikes against Iran. "This might end again in a wider conflict," he warned. Follow the leverage, not the rhetoric.
Both sides are testing limits. Why It Matters: The closure of the Strait of Hormuz directly threatens a worsening global energy crunch. Oil prices could spike significantly.
This situation also increases the likelihood of renewed, wider fighting in the Middle East, drawing in more regional and international actors. The humanitarian cost of such an escalation would be immense. For consumers globally, the economic impact would be immediate and severe. - Iran reversed its decision to open the Strait of Hormuz after the US maintained its port blockade. - The IRGC fired upon a commercial vessel, leading to a halt in maritime traffic through the strait. - US President Trump issued a direct military threat to Iran if a deal is not reached. - Nuclear enrichment capabilities remain a central point of contention in ongoing negotiations.
American negotiators are set to arrive in Islamabad, Pakistan, on Monday. Their mission is to strike a deal. The ceasefire in the region is scheduled to end on April 22.
This deadline looms large. All parties will watch for any shifts in Iran's control over the Strait of Hormuz. The question remains: can diplomacy avert further military confrontation, or will the current brinkmanship lead to a wider conflict that no one truly desires?
