British Prime Minister Keir Starmer declared that the United Kingdom will not participate in the United States’ proposed blockade of the Strait of Hormuz, distancing London from President Donald Trump’s latest escalation against Iran.Speaking on BBC Radio, Starmer said, "We are not supporting the blockade," and added that the UK will not be "dragged into the US‑Israel war on Iran."The Strait of Hormuz is a strategic chokepoint through which about 20 % of the world’s oil supplies transit in peacetime. Starmer stressed that reopening the waterway is vital for global energy security and that the UK’s diplomatic efforts over recent weeks have focused on that goal.Meanwhile, the US Central Command announced it would block all maritime traffic entering or leaving Iranian ports from 14:00 GMT, though it provided few details on how the blockade would be enforced. The statement claimed the action would be applied impartially to vessels of all nations, yet it also noted that ships bound for non‑Iranian ports would not be impeded.President Trump, in a lengthy social‑media post, framed the operation as a mission to clear mines and prevent Iran from profiting from control of the strait.In a parallel diplomatic move, French President Emmanuel Macron said France and the United Kingdom will convene a conference in the coming days aimed at restoring freedom of navigation, reaffirming that “no diplomatic effort will be spared” to end the US‑Israel conflict over Iran.Nicole Grajewski, an assistant professor at Sciences Po, warned that the US blockade constitutes “more than a minor coercive signal” and effectively marks a resumption of hostilities.Other allies echoed criticism: Spanish Defence Minister Margarita Robles called the plan “makes no sense,” Turkish Foreign Minister Hakan Fidan urged “negotiations with Iran and the swift reopening of the strait,” and Chinese Foreign Ministry spokesman Guo Jiakun emphasized that the strait’s security is “in the common interest of the international community.”Starmer’s stance reflects a careful balancing act—maintaining NATO solidarity while refusing to endorse direct military pressure on Iran—highlighting the complex geopolitics surrounding one of the world’s most crucial maritime corridors.

President Donald Trump has signaled that the U.S. Navy will enforce a blockade of the Strait of Hormuz, targeting any vessel that has paid a toll to Iran. The announcement sent oil futures soaring past $100 per barrel on Monday, reviving fears of a deeper global energy crisis. U.S. Central Command later clarified that the operation would focus on ships entering or leaving Iranian ports, a narrower scope than the initial threat to shut the entire strait. Nonetheless, experts say the move would still choke a critical chokepoint in world oil supply. "Anything that removes oil from the market pushes prices higher, which in turn lifts gasoline costs," explained Trita Parsi, co‑founder of the Quincy Institute. He warned that if Iran’s allies, notably the Houthis in Yemen, retaliate by closing the Bab al‑Mandeb strait, oil could surge above $150 a barrel. Bab al‑Mandeb serves as an alternative route for Gulf oil to reach the Red Sea and Indian Ocean. Its closure would compound the disruption already caused by the Hormuz threat. Since the start of the U.S.–Israeli conflict on February 28, Iran has limited traffic through Hormuz, allowing only a handful of vetted ships. Windward estimates that about 3,200 vessels were stranded west of the strait as of Saturday. Former chief economist Anas Alhajji of NGP Energy Capital Management expects non‑Iranian carriers to avoid the strait regardless of U.S. assurances, citing rising insurance premiums and the risk of Iranian retaliation. "The Trump blockade of Iranian ports is effectively a blockade of the Hormuz Strait," he told Al Jazeera. The ripple effects extend beyond fuel. Higher oil and gas prices will lift the cost of chemicals, fertilizers and plastics feedstocks, analysts say. Cameron Johnson, senior partner at Tidalwave Solutions, predicts a rapid increase in raw‑material prices if the blockade persists into late April or early May. "The wild card is the timeframe," Johnson noted. "If it’s a short‑term negotiating tactic, the market may absorb it, but a prolonged blockade will spike global commodity prices." Supply‑chain experts warn of broader repercussions. Deborah Elms of the Hinrich Foundation highlighted that rising fabric costs and packaging shortages could strain food production and consumer goods later in the year. Industry observer Chad Norville of Rigzone said the mere threat erodes confidence in the strait’s stability, likely driving up insurance costs and reducing daily trade volumes. In sum, a U.S. blockade of Iranian ports would mark a stark reversal of recent policy, which had briefly eased sanctions to alleviate the energy crunch. The potential escalation underscores how geopolitical moves can quickly translate into higher energy bills and broader economic strain worldwide.

The United States military confirmed that, beginning at 10 a.m. Eastern Time (14:00 GMT) on April 13, all maritime traffic entering or leaving Iranian ports will be blocked. The directive, issued by U.S. Central Command (CENTCOM), targets vessels of every nation operating in the Gulf and the Gulf of Oman, but explicitly excludes ships merely transiting the Strait of Hormuz to non‑Iranian ports, marking a narrower scope than former President Donald Trump’s broader strait‑wide threat. This decisive action follows the abrupt end of marathon peace talks in Islamabad, where negotiators failed to secure a memorandum of understanding with Tehran. The stalemate has revived fears of renewed hostilities, prompting the U.S. to leverage maritime pressure as a bargaining chip. Financial markets reacted sharply: U.S. crude oil prices surged 8 % to $104.24 per barrel, while the benchmark Brent crude rose 7 % to $102.29. The spikes reflect investor anxiety over potential disruptions to the flow of oil and liquefied natural gas that currently passes through the Strait of Hormuz, a chokepoint responsible for roughly one‑fifth of global energy shipments. Since the February 28 launch of a joint U.S.–Israel operation against Iran, the strait’s traffic has dwindled to a trickle. Iran continues to navigate its own vessels and has allowed limited passage for foreign ships, while discussing a post‑conflict toll system for the waterway. In response to the blockade threat, Iran’s Islamic Revolutionary Guard Corps warned that any U.S. warship attempting to enforce the measure would breach the existing U.S.–Iran ceasefire—set to expire on April 22—and would be "dealt with severely." Iranian Foreign Minister Abbas Araghchi blamed the United States for the diplomatic failure, accusing U.S. negotiators of "shifting the goalposts" when a deal was "just inches away." Academic commentary echoed regional concerns. Zohreh Kharazmi, an associate professor at the University of Tehran, asserted that the United States "is not in a position to dictate" Iranian maritime movements and warned that a prolonged standoff would quickly reveal which side—"the resilience of the Islamic Republic or the resilience of global markets"—would suffer first. While the blockade targets Iranian ports, CENTCOM emphasized that it will not impede freedom of navigation for vessels merely passing through the Strait of Hormuz, a subtle but significant concession aimed at avoiding a full‑scale maritime confrontation.

President Donald Trump declared that the U.S. Navy will commence a blockade of the Strait of Hormuz immediately after peace talks between Washington and Tehran in Pakistan ended without an agreement. In a social‑media post, Trump labeled Iran’s actions as “extortion” and warned that American warships would hunt down and interdict any ship that has paid Iran a toll to traverse the waterway, while also beginning mine‑clearing operations. Iran’s Revolutionary Guard responded that civilian vessels may still cross the strait under “specific regulations,” but any military craft attempting entry would be deemed a breach of the cease‑fire and would be “dealt with severely.” Since the February 28 war launched by the United States and Israel, Iran has effectively taken control of the strategic chokepoint, a route that carries about 20% of the world’s oil and liquefied natural gas shipments. Traffic has now dwindled to a trickle, sending shockwaves through the global economy and raising alarm among Gulf Cooperation Council (GCC) states. Al Jazeera correspondents noted that the rhetoric from the White House has amplified “alarm bells” across the GCC, where leaders had hoped the two‑week ceasefire would evolve into a longer‑term peace framework. Oman’s foreign minister, Badr Albusaidi, urged on social media that the ceasefire be extended and that all parties make “painful concessions” to avoid a return to war. Trump’s statements also included a stark threat: any Iranian forces that fire on U.S. or “peaceful” vessels would be “blown to hell.” He claimed the blockade would involve “other countries” and that the United Kingdom, along with “a couple of other nations,” were dispatching minesweeper vessels to assist – a claim the British government has not confirmed. Domestic criticism emerged quickly. Democratic Senator Mark Warner told CNN he “doesn’t see how blockading the strait will compel Iran to open it,” questioning the strategic logic behind the move. Iran denied U.S. allegations that two of its warships had recently passed through the strait for mine‑clearing, warning that any military vessel attempting such a passage would meet a “strong response.” Tehran officials have floated the idea of instituting a post‑conflict toll system for vessels using the waterway, a prospect that could further entrench Iran’s leverage over global energy flows. Analysts warn that heightened tensions in the Hormuz corridor could push oil prices higher, amplifying inflationary pressures worldwide. As the situation unfolds, mediators continue to press both sides to resume diplomatic talks and avoid a broader escalation.

The United States and Iran left Islamabad without a peace deal, ending the most senior diplomatic encounter between the two nations since the 1979 Islamic Revolution. Vice President JD Vance, who led the U.S. delegation, told reporters that Tehran "refused to accept our terms" after a marathon 21‑hour session. Vance emphasized that the United States requires a "fundamental commitment" from Iran not to pursue nuclear weapons or the associated delivery systems. "We need an affirmative pledge that they will not seek a nuclear weapon, and they will not seek the tools that would enable them to quickly achieve a nuclear weapon," he said. Iran’s Ministry of Foreign Affairs, represented by spokesperson Esmaeil Baghaei, cautioned that no one expected a single‑session resolution. "Naturally, from the beginning, we should not have expected to reach an agreement in a single session," he told state broadcaster IRIB, adding that Tehran remains "confident that contacts with Pakistan and other regional friends will continue." Pakistan called on both parties to honor the ceasefire and pursue a durable peace. Foreign Minister Ishaq Dar expressed gratitude for the mediation efforts, stating, "We hope the two sides continue with a positive spirit to achieve durable peace and prosperity for the entire region and beyond." The stalled talks occur against the backdrop of a war that began on February 28, when the United States and Israel launched a campaign against Iran. The conflict has since spread across the Middle East, causing over 2,000 fatalities and extensive damage to both military and civilian infrastructure. One of the war’s most destabilizing effects has been a global energy crisis, as Iran tightened control over the Strait of Hormuz—a chokepoint through which roughly 20 % of the world’s oil and gas exports flow. The delegations, led by Vance for the United States and Iranian Parliament Speaker Mohammad Bagher Qalibaf, also discussed how to sustain a ceasefire that is already under strain from deep disagreements and Israel’s ongoing attacks on Hezbollah in Lebanon.

The United States’ senior envoy, Vice President JD Vance, said the marathon talks in Islamabad collapsed because Iran would not abandon its nuclear weapons programme, a stance Tehran’s representatives dismissed as a lack of US goodwill. Vance, who departed Islamabad on Sunday after a 21‑hour session with Iranian officials, reiterated that Washington’s red lines required an "affirmative commitment" from Tehran that it would not pursue a nuclear weapon or the means to acquire one quickly. He described the stalemate as "bad news for Iran much more than it is for the United States." Iranian parliament speaker Mohammad Bagher Ghalibaf countered that, despite offering "constructive initiatives," the US failed to win the trust of the Iranian delegation, leaving it to Washington to decide whether it can regain that confidence. Iran’s foreign ministry downplayed expectations, stating that no one anticipated a deal in a single session and emphasizing continued regional contacts, while the semi‑official Tasnim news agency blamed "excessive" US demands for the impasse. The talks took place under a 14‑day ceasefire agreed by the US, Iran and Israel, with Pakistan’s foreign minister Ishaq Dar urging both sides to honour the pause and offering to facilitate renewed dialogue. The conflict, which began on 28 February, has already claimed over 3,000 lives in Iran, more than 2,000 in Lebanon, and dozens across the Gulf region, while inflicting extensive infrastructure damage. Israeli security cabinet minister Ze’ev Elkin warned that Iran is "playing with fire," even as he left the door open for further negotiations. These were the first direct US‑Iran talks in more than a decade and could determine the fate of the fragile ceasefire and the reopening of the Strait of Hormuz—a chokepoint for roughly 20 % of global energy supplies. The war has already sent international oil prices soaring. In addition to Vance, US special envoy Steve Witkoff and former President Trump’s son‑in‑law Jared Kushner met with Ghalibaf and Iranian foreign minister Abbas Araghchi for two hours before a brief recess. The Iranian delegation arrived in black mourning attire for the late Supreme Leader Ayatollah Ali Khamenei and carried shoes and bags belonging to children killed in a school bombing near a military compound—a strike the Pentagon says is under investigation, with some reports suggesting US involvement. Pakistani security forces sealed off Islamabad, a city of over two million, underscoring Pakistan’s newly prominent mediating role after a year of diplomatic isolation. The US military announced it was "setting conditions" to clear mines and allow warships to pass through the Strait of Hormuz, a claim Iran’s state media denied. Prior to the talks, a senior Iranian source told Reuters that the US had agreed to release frozen Iranian assets held in Qatar and other banks, a statement the US later denied. Tehran’s broader demands include control over the strait, payment of war reparations, a region‑wide ceasefire—including in Lebanon—and the collection of transit fees from shipping traffic. President Trump’s minimum objectives remain the free passage of global shipping through the strait and the crippling of Iran’s nuclear enrichment capability to prevent the development of an atomic bomb.

The U.S. Central Command (CENTCOM) reported that the destroyers USS Frank E. Peterson and USS Michael Murphy "transited the Strait of Hormuz and operated in the Arabian Gulf" as part of a mission to clear sea mines allegedly laid by Iran’s Islamic Revolutionary Guard Corps (IRGC).Admiral Brad Cooper hailed the operation as a turning point in the U.S.–Israeli campaign against Iran, saying the navy was establishing a "new passage" to restore safe commercial flow. Iran’s Khatam al‑Anbiya Central Headquarters immediately rejected the claim, stating that any vessel movement in the strait remains under the "Armed Forces of the Islamic Republic of Iran" and that the U.S. report is "strongly denied." The strait, a narrow chokepoint through which roughly 20% of the world’s oil and natural gas transits, has been a flashpoint since the February 28 U.S.–Israel attacks that prompted Iran to restrict passage to pre‑approved ships. The closure spiked global fuel prices and disrupted both commercial and military traffic. Analysts, such as Maria Sultan of the South Asian Strategic Stability Institute, argue that any U.S. navigation would require Tehran’s explicit permission, underscoring the strategic leverage Iran holds over the waterway. Simultaneously, senior delegations from the United States and Iran met in Islamabad for historic face‑to‑face talks—the highest‑level engagement since the 1979 Islamic Revolution. The negotiations, sparked by a preliminary ceasefire announced earlier in the week, focus on contentious issues including Iran’s nuclear program, frozen assets, and the future of Israeli operations in Lebanon. Both parties acknowledge that control of the Strait of Hormuz remains a major point of disagreement. Iran has signaled willingness to temporarily reopen the channel for commercial shipping but insists on maintaining leverage, proposing tolls to compensate for war damages. The United States, however, deems continued Iranian control a "non‑starter." U.S. President Donald Trump used his Truth Social platform to assert that Iran is "losing big" and to downplay the strait’s importance to the United States relative to its allies, claiming the mine‑clearing effort benefits nations such as China, Japan, South Korea, France, and Germany. Al Jazeera’s on‑the‑ground correspondents noted that despite a "deficit of trust," negotiators are working late into the night to bridge gaps, though fundamental disagreements over the strait’s governance persist.

US President Donald Trump has announced that the Strait of Hormuz will reopen 'fairly soon' with or without Iran's assistance, as the US and Iran prepare for peace talks in Pakistan. The strait, a critical maritime chokepoint, has been effectively blocked by Iran, disrupting approximately one-fifth of global oil and natural gas flows.Speaking to reporters, Trump said the US would 'open up the Gulf' and that other countries were ready to 'help out'. He emphasized that ensuring Iran does not possess nuclear weapons is the priority in any agreement, and the strait would open 'automatically' if a deal is reached.Despite a two-week ceasefire between the US and Iran, shipping in the strait remains at an effective standstill. Only two vessels passed through the strait on Friday, down from five the previous day. More than 600 vessels, including 325 tankers, are still stranded in the Gulf due to the blockage.US Vice President JD Vance and Iranian parliamentary speaker Mohammad Bagher Ghalibaf are set to lead negotiations in Islamabad aimed at securing a permanent end to the war. The US and Iran have offered conflicting messages on the agreed-upon terms for the negotiations, including the contents of a 10-point plan put forward by Tehran.

UK Prime Minister Keir Starmer and former US President Donald Trump convened to explore military options aimed at reopening the Strait of Hormuz. The discussion reflects heightened concern over recent disruptions that have threatened the flow of oil through the narrow Gulf passage. The Strait of Hormuz, a critical chokepoint through which roughly 20% of global petroleum shipments transit, has faced intermittent closures due to regional tensions. Both leaders emphasized that ensuring safe passage is essential for stabilising global energy markets and preventing price spikes. While specific operational plans were not disclosed, the dialogue reportedly focused on coordinated naval patrols and the potential deployment of rapid-response forces to deter any further blockades. Analysts note that such a joint stance could signal a broader Western commitment to maintaining freedom of navigation in the Persian Gulf. Experts caution that any military escalation carries risks, including the possibility of widening the conflict with regional actors. Nonetheless, the meeting highlights the strategic priority placed on the Strait by both London and Washington, aiming to safeguard a vital artery of the world economy.
