Pakistani officials have expressed confidence that a significant diplomatic breakthrough could emerge from the latest round of U.S.–Iran negotiations, with Islamabad intensifying its role as mediator in a conflict that has already claimed thousands of lives. On Wednesday, a senior Pakistani delegation led by Army Chief Asim Munir landed in Tehran to deliver a message from Washington to Iranian leaders, according to Iran’s Press TV. The envoy was welcomed by Foreign Minister Abbas Araghchi, who thanked Pakistan for its "gracious hosting of dialogue" and indicated that groundwork is being laid for a second U.S.–Iran round of talks. Al Jazeera analyst Osama Bin Javaid noted that Pakistani officials anticipate a "major breakthrough on the nuclear front," with messages shuttling continuously between the two capitals. The core dispute centers on the length of any Iranian enrichment freeze—ranging from a proposed five‑year to a twenty‑year moratorium—and the disposition of Iran’s 440 kilograms of highly enriched uranium. Options under discussion include exporting the material, diluting it to natural uranium, or reducing enrichment to a maximum of 3 %. Pakistan’s diplomatic push follows a stalled U.S.–Iran session in Islamabad that ended without a cease‑fire agreement. Mediators are now concentrating on three pivotal issues: the nuclear programme, control of the strategic Strait of Hormuz—which Tehran has effectively closed, driving up global oil prices—and compensation for wartime damages. The conflict, ignited by the United States and Israel on 28 February, has resulted in more than 3,000 Iranian deaths and prompted retaliatory strikes against Gulf states. It has also reignited hostilities between Israel and Hezbollah in Lebanon, where over 2,000 casualties have been reported since early March. A cease‑fire declared on 8 April halted attacks in Iran and the Gulf, yet Israeli operations in southern Lebanon have persisted. Simultaneously, Pakistan’s Prime Minister Shehbaz Sharif embarked on a regional tour to Saudi Arabia, Qatar and Turkey, a move described by Bin Javaid as a "double‑pronged strategy" aimed at neutralising opposition to a potential deal. According to the White House, President Donald Trump signalled optimism on Tuesday, suggesting the war could conclude within "an amazing two days" and that it is "very close to over." Press Secretary Karoline Leavitt later described the Pakistan‑facilitated talks as "productive and ongoing," adding that further negotiations are likely to take place in Islamabad. Iran’s Ministry of Foreign Affairs confirmed that message exchanges with the United States have continued via Pakistani channels, with spokesperson Esmaeil Baghaei stating that Tehran’s positions have been communicated. Nevertheless, tensions linger. A U.S. naval blockade of Iranian ports in the Strait of Hormuz remains active; U.S. Central Command reported turning back nine vessels as of Wednesday. Iran’s military denounced the blockade as a breach of the cease‑fire, and the Iranian joint command chief, Ali Abdollahi, warned of possible retaliation by disrupting trade routes through the Red Sea, the Gulf and the Sea of Oman if the blockade persists.

The United States is set to move **over 10,000 additional service members** into the Middle East before the end of April, according to officials speaking anonymously to The Washington Post. The reinforcement is intended to heighten pressure on Iran while the current cease‑fire, declared a week ago, remains in force until April 22. Approximately 6,000 troops will embark aboard the USS George H.W. Bush carrier and its escort vessels, which are transiting around Africa to join the existing carrier presence. An additional 4,200 personnel from the Boxer Amphibious Ready Group and the 11th Marine Expeditionary Unit are expected to arrive later in the month. These deployments bring the total number of U.S. forces engaged in the conflict since its start on February 28 to roughly 50,000 troops. With the arrival of the George H.W. Bush, the region will host three U.S. carriers: the newly arrived vessel, the USS Abraham Lincoln, and the USS Gerald Ford, all of which have already taken part in combat operations against Iran. Concurrently, U.S. Central Command (CENTCOM) announced on social media that its naval blockade of Iranian maritime trade is "fully implemented" and that American forces have "completely halted economic trade" to and from Iran by sea. However, maritime‑tracking data released on Tuesday showed several ships departing Iranian ports and navigating the Strait of Hormuz, suggesting the blockade’s effectiveness may be limited. Amid the military buildup, diplomatic channels remain active. President Donald Trump told The New York Post that a new round of negotiations with Iran could be convened in Pakistan within two days, following a marathon session in Islamabad that ended without a breakthrough. The previous high‑stakes talks failed to secure a lasting peace agreement, and the cease‑fire is slated to expire on April 22. According to the Washington Post sources, the fresh troop influx is designed to give the U.S. administration leverage in ongoing talks while preserving the option for "additional strikes or ground operations" if negotiations falter. This dual strategy underscores Washington’s intent to maintain both diplomatic and kinetic pressure on Tehran as the regional conflict evolves.

Washington, D.C. – The U.S. Senate voted 47‑52 to reject a resolution that would have limited President Donald Trump’s power to wage war against Iran, marking the fourth defeat of the measure despite weekly attempts by lawmakers. The vote follows a two‑week ceasefire agreed upon last week, though subsequent negotiations in Islamabad failed to produce a longer‑term deal. Both sides have indicated openness to a second round of talks. President Trump’s earlier threats, including a statement on April 7 that a “whole civilisation will die tonight,” intensified congressional calls for constraints on his war‑making authority. Party lines largely dictated the outcome: Republican Rand Paul voted in favor, while Democrat John Fetterman broke with his party to oppose the resolution. Supporters argue that Trump acted beyond constitutional limits when he joined Israel in launching the February 28 offensive. The U.S. Constitution reserves the declaration of war for Congress, allowing presidents to act unilaterally only in cases of immediate self‑defence. Senator Chris Murphy, speaking before the vote, described the conflict as a “bungled, mismanaged war” that has failed to meet the administration’s objectives. He criticized the lack of transparency and oversight, noting that the war is costing “billions of dollars every week,” has claimed “over a dozen American lives,” and is destabilising economies worldwide. Republican Senator Jim Risch defended Trump’s actions, dismissing the resolution as “same old, same old” and asserting that the president has both the right and duty to act. The House of Representatives is slated to consider its own war‑powers resolution this week, with a higher likelihood of passage given growing wariness among some Republicans. Even if both chambers approved the measure, Trump could veto it, requiring a two‑thirds supermajority to override. Under the War Powers Act of 1973, Congress must either authorize the military action or approve a 30‑day extension when the conflict reaches its 60‑day mark at the end of April. Failure to do so would legally compel the president to begin withdrawing forces. U.S. blockade updates: U.S. Central Command reported that no vessels have successfully breached the blockade of Iranian ports in the Strait of Hormuz over the past 48 hours, with nine ships complying with orders to turn back. The U.S. Navy warned that vessels attempting to transit will be boarded for interdiction and seizure. Treasury Secretary Scott Bessent announced a forthcoming set of financial measures described as the “financial equivalent” of military attacks, while noting that some sanctions had been lifted to ease soaring global energy prices. White House spokesperson Karoline Leavitt said the administration has not formally requested an extension of the ceasefire, which is set to expire next week, but expressed optimism about a second round of talks in Islamabad. Iran’s state‑run television reported that a high‑level Pakistani delegation arrived in Tehran to coordinate new negotiations. Meanwhile, Major‑General Ali Abdollahi of the IRGC warned that the ongoing naval blockade could jeopardise the fragile ceasefire, describing it as a “prelude to a violation of the ceasefire.”

On Tuesday, shipping data from LSEG and Kpler confirmed that at least three tankers entered the Gulf via the Strait of Hormuz, including the Panama‑flagged Peace Gulf, which is bound for Hamriyah port in the United Arab Emirates. Earlier that day, two U.S.–sanctioned vessels, the Rich Starry and the Elpis, also transited the waterway. Because none of these ships were destined for Iranian ports, they remain exempt from the U.S. blockade that began on Monday. The U.S. Central Command (CENTCOM) announced that, as of 10 a.m. ET (14:00 GMT) on Monday, a naval blockade was in effect against all maritime traffic to and from Iranian ports, in line with the presidential order issued by former President Trump. The directive applies to "vessels of all nations" operating in Iranian coastal waters, including the Arabian Gulf and the Gulf of Oman. Tehran has warned of possible retaliation against ports in neighboring Gulf states. In response to the blockade, the Islamic Revolutionary Guard Corps (IRGC) ordered every ship to follow a newly‑drawn navigation map that forces vessels to enter the strait north of Larak Island and exit south of it, citing the risk of anti‑ship mines in the former main traffic zone. Before the conflict, the strait functioned like a divided highway with two dedicated lanes—each about 3.2 km long—carrying roughly one‑fifth of the world’s oil and gas shipments. The IRGC now classifies the original lanes as "restricted" and has effectively closed them. Ship traffic has collapsed by **more than 95 %** since the war began. Kpler’s tracking data shows that only **279 vessels** passed through the strait between Feb. 28 and Apr. 12, a stark contrast to the pre‑war average of around **100 ships per day**. Even after a cease‑fire took effect on Apr. 8, a mere **45 ships** have entered or exited the waterway. The disruption has left hundreds of tankers and other vessels stranded in the Gulf, slashing global oil and gas supplies by an estimated **20 %**—the largest fuel‑supply shock on record. Damage to Gulf energy infrastructure and the sharp reduction in shipments have pushed crude prices up by roughly **50 %**, with Asian importers bearing the brunt of the price spike. According to the same Kpler data, **22 ships** have been attacked in the Strait of Hormuz since the conflict started. The incidents are distributed as follows: eight in United Arab Emirates waters, six in Omani waters, two each in Iraqi and Qatari waters, and one each in Bahraini, Kuwaiti, Saudi and Iranian waters. These figures underscore the strategic vulnerability of the world’s most critical energy chokepoint and highlight how the combined effect of the U.S. naval blockade and Iran’s alternate routing has reshaped global shipping patterns and commodity markets.

The U.S. military announced that, starting at 14:00 GMT on Monday, it will enforce a blockade of every Iranian port, a step taken after President Donald Trump ordered a naval closure of the Strait of Hormuz—the waterway through which roughly one‑fifth of global crude oil normally flows. The blockade comes on the heels of stalled peace negotiations in Islamabad, where talks between Washington and Tehran collapsed without an agreement despite a prior cease‑fire pledge. Trump’s escalation has already driven crude prices above $100 per barrel and unsettled Asian equity markets, with the Nikkei 225 down 0.84%, the Topix slipping 0.42% and South Korea’s Kospi falling 1.83%. Iran’s response is equally forceful. The Islamic Revolutionary Guard Corps warned that any vessel entering the strait would be deemed a breach of the cease‑fire and dealt with “harshly and decisively,” insisting it has “full control” and threatening a “deadly vortex” for any misstep. Navy chief Shahram Irani dismissed Trump’s threat as “ridiculous and funny,” while state television said Iranian forces are closely monitoring U.S. movements. Foreign Minister Abbas Araghchi lamented “maximalism, shifting goalposts, and blockade” that undermined a near‑final Islamabad memorandum, quoting, “Good will begets good will. Enmity begets enmity.” Parliament speaker Mohammad Bagher Ghalibaf pledged resistance and mocked U.S. gasoline prices, posting a map of Washington‑area pump prices and predicting nostalgia for $4‑$5 gas. U.S. Central Command clarified that the blockade will stop all vessels bound for or from Iran, while traffic to non‑Iranian ports will continue unhindered. Trump also warned that any ship that has paid an “illegal toll” to Iran will be intercepted on the high seas, and he publicly criticized Pope Leo XIV for urging an end to the conflict. In Lebanon, Israeli airstrikes have killed at least five people, bringing the country’s overall death toll to 2,055. Hezbollah retaliated with a rocket barrage aimed at northern Israeli towns, citing violations of a cease‑fire. The United Nations Interim Force in Lebanon (UNIFIL) reported that an Israeli tank rammed peace‑keeping vehicles twice in the south. Israel’s Prime Minister Benjamin Netanyahu visited troops on the Lebanese border, claiming that Hezbollah’s invasion threat has been neutralized, though he acknowledged that hostilities continue within the security zone. On the energy front, shipping through the Hormuz corridor has “immediately halted,” according to Lloyd’s List, with several vessels turning back after the blockade announcement, further tightening global oil supplies.

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.

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.

Iranian military units have launched a coordinated search for the two pilots of a United States F‑15 fighter jet that was struck by an Iranian air‑defence system over the country's southwest region. The operation, reported by the state‑run Fars news agency, is the first documented crew‑recovery effort since the US‑Israeli war with Iran began on 28 February. State media released images showing the aircraft's wreckage, including an ejection seat attached to a parachute, underscoring the seriousness of the incident. Reuters cited two U.S. officials confirming that a fighter jet was downed and that a search‑and‑rescue mission is underway for any survivors. Iranian Parliament Speaker Mohammad‑Bagher Ghalibaf used the event to mock President Donald Trump’s repeated claims of victory, posting on social media that the conflict had been reduced from "regime change" to a plea for the location of the pilots. According to Iranian reports, the downed aircraft was an F‑15 likely crewed by two pilots. The Pentagon and U.S. Central Command (CENTCOM) have not issued an immediate comment, a pattern consistent with past Iranian claims that CENTCOM swiftly denied. Local Iranian television broadcast footage of the jet's debris, and officials appealed to civilians to remain vigilant for any survivors. The governor of Kohgiluyeh and Boyer‑Ahmad province announced that anyone who captures the crew would receive special commendation, as relayed by the semi‑official ISNA news agency. U.S. lawmakers responded with statements of support. Senate Minority Leader Chuck Schumer posted on X, "I’m praying for the safe return of the crew aboard the fighter jet and all of those working to rescue them in these dangerous conditions." Since the war's onset, the United States has reported the loss of three F‑15s in a friendly‑fire incident over Kuwait and a refuelling aircraft that crashed in Iraq, killing six crew members. Iran, meanwhile, claims to have downed dozens of U.S. drones and continues to assert that its new air‑defence system, introduced after the 12‑day war, remains operational. While President Trump and his advisers repeatedly assert that the United States has neutralised Iran’s air‑defences, the downing of the jet and the ensuing search highlight the ongoing volatility of the conflict.
