Speaking at a Turning Point USA event, Vance said distrust between Washington and Tehran remains a fundamental obstacle to any durable agreement. “There is a lot of, of course, mistrust between Iran and the United States of America.

You are not going to solve that problem overnight,” he said, while adding that Iranian negotiators appeared willing to reach a deal.Vance, who participated in recent negotiations held in Pakistan, said he was cautiously optimistic about the trajectory of talks.

“I feel very good about where we are,” he said, signaling confidence in ongoing diplomatic efforts despite recent setbacks.Donald Trump said on Tuesday that discussions aimed at ending the Iran war could resume in Pakistan within days, following the collapse of negotiations over the weekend.

The breakdown prompted Washington to impose a blockade on Iranian ports, escalating economic and military pressure on Tehran.A two-week ceasefire between US and Iranian forces remains in effect, with one week remaining, offering a limited window for diplomatic engagement.

The pause in hostilities follows weeks of intensified conflict that began on February 28, when US and Israeli forces launched strikes on Iran.Tehran retaliated with attacks targeting Israel and Gulf states hosting US military bases, expanding the geographic scope of the conflict.

Subsequent US-Israeli operations inside Iran, along with Israeli strikes in Lebanon, have resulted in significant casualties and widespread displacement, according to official accounts.

The evolving situation underscores the complexity of negotiations, with diplomatic momentum constrained by entrenched mistrust and ongoing military developments.

“I welcome the ceasefire agreement reached overnight, which will bring a moment of relief to the region and the world,” Starmer said in a statement, adding that efforts must now focus on sustaining the truce and reopening the vital maritime route.

Starmer said Britain would work with partners to support and uphold the ceasefire and turn it into a lasting agreement, while seeking to protect global economic stability by restoring access through the Strait of Hormuz, a key artery for oil and gas shipments.

The visit comes amid heightened diplomatic activity following the ceasefire, with London positioning itself in efforts to stabilise energy flows and reduce disruption to global markets.

Starmer, who has faced criticism from U.S. President Donald Trump for not backing recent U.S. and Israeli strikes on Iran, has in recent days convened multinational discussions on securing the reopening of the strait.

According to the British government, the prime minister’s discussions in the Gulf will focus on diplomatic measures to reinforce the ceasefire and prevent further escalation that could threaten international trade.

The trip had been scheduled prior to the ceasefire announcement, but now takes on added significance as global attention turns to ensuring uninterrupted passage through one of the world’s most strategically important waterways.

British Foreign Secretary Yvette Cooper also held talks with U.S. Secretary of State Marco Rubio on Tuesday, discussing coordinated diplomatic steps to reopen the strait, including a UK-led meeting last week that brought together more than 40 countries to address the issue.

Checkpoints staffed by security personnel and volunteers have proliferated across the capital since the conflict began, initially marked by military vehicles and road barriers. While some visible fortifications have been scaled back following recent airstrikes, residents say patrols remain widespread, with teenagers now playing an increasingly prominent role.

Witness accounts describe adolescents aged 13 to 14 manning checkpoints, stopping vehicles and conducting searches. A 28-year-old resident told AFP that she was stopped at two checkpoints in northern Tehran, where teenage boys carrying weapons inspected her phone and personal belongings without consent, calling the encounter intrusive.

Another resident said that beyond formal military checkpoints, groups of youths in private vehicles were independently stopping cars, opening doors and checking dashboards and mobile devices.Authorities have acknowledged lowering the minimum age for Basij recruitment to 12, citing high levels of interest among younger volunteers.

Rahim Nadali, an official with the Revolutionary Guards in Tehran, said on state television that the decision reflected demand from children seeking to participate in defense efforts.The Basij, an auxiliary force under the Islamic Revolutionary Guard Corps, has historically played a central role in internal security operations.

It was also reported to have been involved in suppressing anti-government protests in January, during which thousands were killed.The expanded use of minors has drawn concern from rights groups and analysts. Some observers interpret the move as an indication of manpower shortages, while others see it as a sign of a more hardline approach by authorities seeking to consolidate control amid external and internal pressures.

Mohammad Bagher Ghalibaf, Iran’s parliamentary speaker, urged supporters to maintain a presence on the streets, framing domestic mobilization as part of a broader strategic effort alongside military and maritime pressures, including tensions around the Strait of Hormuz.

Analysts say the intensified street presence is aimed at deterring potential unrest, particularly after calls from U.S. President Donald Trump and Israeli Prime Minister Benjamin Netanyahu encouraging opposition activity at the outset of the war.

In addition to checkpoint duties, pro-government groups have organized nighttime patrols, using vehicles equipped with loudspeakers to broadcast slogans and display flags in residential areas.

Hamidreza Azizi, a visiting fellow at the German Institute for International and Security Affairs, said the government was increasingly reliant on a core base of ideologically committed supporters to maintain order. He noted that this strategy reflects deeper challenges to the state’s legitimacy but has proven effective in sustaining control during wartime conditions.

Human Rights Watch said the recruitment of children under 15 for military roles could constitute a war crime under international law and warned that their deployment exposes them to heightened risks, including potential targeting in military strikes.

Bill Van Esveld, the group’s associate director for children’s rights, said the policy suggested authorities were willing to endanger minors to bolster security capacity.

The attack occurred early on Saturday, with security sources confirming that the residence of Barzani was targeted. No immediate details were provided on casualties or damage.

Air defense systems also intercepted and shot down another drone near a base used by Kurdish Peshmerga fighters in Duhok province, the sources added.

Sudani condemned the incident and held a phone call with Barzani following the attack, according to a statement from his office. He directed the formation of a joint federal and Kurdistan regional security and technical team to investigate the strikes and identify those responsible.

The move reflects Baghdad’s effort to manage growing instability in the north, where overlapping security jurisdictions between federal and regional authorities complicate response mechanisms.

The incident comes amid a surge in attacks involving Iran-aligned militias and Kurdish forces, as the broader US–Israel war against Iran increasingly spills into Iraqi territory.

Airstrikes in recent weeks have targeted positions associated with the Popular Mobilization Forces as well as Kurdish Peshmerga units in the Kurdistan Region.

Iraq’s military has accused the United States and Israel of conducting some of these strikes.In parallel, Tehran-backed armed groups have launched attacks on U.S. military installations in Iraq and on the U.S. embassy in Baghdad, underscoring the widening scope of the confrontation.

The victim, believed to be around 60 years old, died in Tel Aviv following a missile impact, according to Magen David Adom, which added that two others sustained minor injuries.

The Israel Defense Forces said it had identified missiles launched from Iran toward Israeli territory, with air defense systems activated to intercept the threat.Search and rescue teams were deployed to multiple impact sites in central Israel, the military said, while witnesses reported seeing missile trails over Jerusalem.

Explosions were also heard in Jericho in the occupied West Bank.Emergency responders were seen at the scene in Tel Aviv, where a main road was partially sealed off following the strike.

Israeli authorities said earlier that at least 18 civilians had been killed since the start of the conflict, including 13 Israelis, four minors, a Filipino caregiver and a Thai national, in missile attacks attributed to Iran.

The military warned that additional missile launches were detected as Saturday approached, indicating the continuation of hostilities.Iran signals retaliationIranian Foreign Minister Abbas Araghchi said earlier that Tehran would impose a “heavy price” for Israeli actions, following reported strikes on major Iranian steel facilities and nuclear sites.

The exchange of attacks marks an intensification of the conflict between the two countries, with both sides continuing cross-border strikes amid mounting civilian casualties.

The announcement comes amid a four-week conflict involving the United States, Israel and Iran that has killed thousands and disrupted global energy markets, driving up oil and liquefied natural gas prices and intensifying inflation concerns worldwide.

Deadline extended amid conflicting claimsTrump said talks with Iran were “going very well” and announced a 10-day pause on threatened attacks on Iranian energy facilities, extending an earlier five-day halt declared on March 23.

The pause is set to expire on April 6 at 2000 EDT.Iran, however, said it was not engaged in direct talks with Washington, and officials indicated the U.S. had not clarified who it was negotiating with, as senior Iranian leadership has been significantly affected by the conflict.

Mediators cited by the Wall Street Journal said Tehran had not requested the 10-day pause, while Trump told Fox News that Iran had sought a shorter, seven-day reprieve. There was no immediate confirmation from Iranian authorities.

The conflict has sharply disrupted shipping through the Strait of Hormuz, a critical artery carrying roughly a fifth of global oil and liquefied natural gas. Oil prices have surged about 40% since hostilities began, with Brent crude rising above $105 per barrel.

Iran has warned it would retaliate against energy infrastructure in the Gulf if U.S. strikes proceed, raising concerns about tit-for-tat attacks on civilian facilities that could further destabilize energy markets and regional economies.Global equities have also come under pressure, with major indexes declining amid uncertainty over the conflict’s trajectory.

The Pentagon is considering deploying up to 10,000 additional troops to the Middle East, according to U.S. media reports, while also confirming the use of uncrewed drone speedboats in operations against Iran.

Trump reiterated that the United States could escalate pressure if Iran fails to comply with demands, including reopening the Strait of Hormuz and curbing its nuclear programme, and said control of Iran’s oil resources remained an option without elaborating.

An Iranian official said a 15-point U.S. proposal conveyed through Pakistan was reviewed by senior leadership and deemed unacceptable as it primarily served U.S. and Israeli interests.

The proposal reportedly included demands to dismantle Iran’s nuclear programme, limit missile capabilities and alter control over key waterways.

Pakistan’s foreign minister said indirect communication channels remain open, with Turkey and Egypt also involved in mediation efforts.Iran has hardened its negotiating stance, seeking guarantees against future military action, compensation for war damage and greater control over maritime routes, while also insisting that Lebanon be included in any ceasefire framework.

Meanwhile, hostilities continued on multiple fronts, with Iran launching missile strikes on Israeli cities including Tel Aviv and Haifa, and Israeli strikes hitting targets in southern and central Iran, resulting in civilian casualties and infrastructure damage.

In a post on Truth Social, Trump said Iranian negotiators were “begging for a deal,” dismissing Tehran’s public stance as inaccurate. Araghchi, speaking on state television, said there had been no direct dialogue with Washington, adding that exchanges via intermediaries did not constitute negotiations.

He said Iran was conveying its positions and warnings through friendly countries.The divergence in messaging comes as military operations continue. U.S. and Israeli forces have conducted extensive strikes on Iranian targets since late February, while Iran has launched retaliatory attacks on Israel, U.S. bases, and Gulf states.

A U.S. Central Command briefing said more than 10,000 targets had been struck, with significant degradation of Iran’s naval, missile, and drone capabilities.

The conflict has disrupted global energy flows, particularly through the Strait of Hormuz, a key transit route for oil and liquefied natural gas. Its effective closure has triggered what officials describe as a severe energy shock, driving up fuel prices and straining supply chains across industries from aviation to agriculture.

Sultan Al Jaber, chief executive of ADNOC, described restrictions on Hormuz as “economic terrorism,” warning of global consequences. Governments are considering intervention measures similar to those deployed during the COVID-19 pandemic, as businesses face rising costs and weakening demand.

The World Food Programme has warned that prolonged disruption could push tens of millions into acute hunger, with farmers and fisheries already facing fuel shortages.

A 15-point U.S. proposal, conveyed to Iran through Pakistan, includes reopening the Strait of Hormuz, curbing Iran’s nuclear and missile programs, and halting support for regional allies, according to Israeli sources familiar with the plan.

The White House has not publicly detailed the proposal.Israeli officials expressed skepticism that Tehran would accept the terms and voiced concern that U.S. negotiators could offer concessions.

Iran, according to regional sources, has insisted that Lebanon be included in any ceasefire framework involving Washington and Israel.

Financial markets reflected fading optimism over a near-term resolution. Global equities weakened on Thursday while oil prices resumed their upward trajectory. Analysts cited diminishing expectations of a ceasefire as a key driver of volatility.

The Pentagon is preparing to deploy additional airborne troops to the Gulf, supplementing Marine units already en route, according to sources. The buildup is intended to expand military options as the conflict risks widening.

United Nations Secretary-General Antonio Guterres warned that the situation could escalate further, urging a shift from military confrontation to diplomacy.

The statement, issued by Iran’s foreign ministry and shared with IMO member states and non-governmental organizations, said vessels that do not “participate in or support acts of aggression” against Iran would be permitted safe passage through the strategic waterway, subject to adherence to safety and security regulations.

However, it specified that vessels, equipment, and assets belonging to what it described as “aggressor parties” including the United States and Israel would not qualify for what it termed “innocent or non-hostile passage.

”Iran said responsibility for any disruption or escalation in the Strait of Hormuz lay with Washington and Tel Aviv, accusing them of waging an “unlawful and destabilising war” that has heightened risks to international shipping and regional stability.

The statement reflects Tehran’s position as tensions remain elevated following the outbreak of war triggered by U.S.-Israeli strikes on Iran on February 28.

The Strait of Hormuz, one of the world’s most critical maritime chokepoints, has been effectively closed since the escalation, contributing to sharp increases in global oil and gas prices.

Iran’s conditional reopening for select vessels introduces limited operational clarity for commercial shipping, though the exclusion of U.S. and Israeli-linked assets underscores the continuing strategic and geopolitical risks in the region.

Sharif, writing on social media platform X, said Pakistan would be “ready and honoured” to facilitate “meaningful and conclusive talks” for a comprehensive settlement, subject to agreement by Washington and Tehran.

His statement comes as the war, involving U.S. and Israeli strikes on Iran and retaliatory attacks, entered its fourth week.Trump said on Monday that U.S. officials had engaged in “very good and productive” discussions with Iran over a “complete and total resolution of hostilities in the Middle East.”

He added that talks began on Sunday and continued into Monday, involving Special Envoy Steve Witkoff and adviser Jared Kushner.

Iranian parliament speaker Mohammad Baqer Qalibaf rejected the U.S. account, saying no talks had taken place and describing reports of negotiations as “fake news,” according to Iranian state-linked statements and sources familiar with the matter.

The divergence underscores the opacity surrounding diplomatic efforts as fighting continues across the region.

The United States and Israel launched strikes on Iran on February 28, citing a lack of progress in negotiations over Tehran’s nuclear programme. Mediator Oman had previously indicated that significant advances had been made in earlier discussions.

Since the strikes, Iran has responded with missile attacks and expanded its actions beyond Israeli territory, targeting countries hosting U.S. bases and striking Gulf energy infrastructure.

The conflict has disrupted global energy markets, with Iran effectively closing the Strait of Hormuz, a critical maritime route through which roughly one-fifth of the world’s oil and liquefied natural gas supplies transit.

The escalation has heightened concerns over supply stability and increased geopolitical risk across the Middle East, prompting renewed international calls for de-escalation through diplomatic channels.

Air raid sirens sounded across Israel early on Sunday, warning of incoming Iranian missiles, after dozens of people were wounded overnight in separate attacks in the southern towns of Arad and Dimona. Israel’s military said it was carrying out strikes on Tehran hours after the Iranian attacks.

Trump on Saturday warned he would “obliterate” Iran’s power plants if Tehran did not fully reopen the Strait of Hormuz within 48 hours, marking a sharp escalation a day after suggesting the conflict could be wound down.

Iran responded on Sunday by warning it would strike U.S. infrastructure, including energy facilities in the Gulf, if Washington followed through on its threat. The warning came as U.S. Marines and heavy landing craft continued moving toward the region.

The exchange of threats has heightened fears that energy installations across key Gulf producers could become direct targets, widening the conflict beyond current theatres of engagement.

The escalating the crisis has disrupted markets, pushing fuel costs higher and intensifying concerns over global inflation. Analysts said the situation has introduced acute uncertainty into financial markets already strained by supply disruptions.

“President Trump’s threat has now placed a 48-hour ticking time bomb of elevated uncertainty over markets,” said Tony Sycamore, an analyst at IG.

He warned that failure to de-escalate could trigger sharp declines in global equities and further spikes in oil prices.

Oil prices rose on Friday to their highest levels in nearly four years after Iraq declared force majeure on oilfields operated by foreign firms, Israel struck a major Iranian gas field, and Tehran retaliated with attacks on neighbouring countries including Saudi Arabia, the United Arab Emirates, Qatar and Kuwait.

Iranian actions have effectively closed the Strait of Hormuz, a narrow passage that carries around a fifth of global oil and liquefied natural gas supplies, triggering what analysts describe as the most severe oil disruption since the 1970s.

The near-closure has also driven European gas prices sharply higher, with increases of up to 35% reported last week, reflecting the strait’s central role in global energy flows.

In a social media post late on Saturday, Trump reiterated his ultimatum, saying the United States would begin targeting Iran’s power infrastructure if the waterway was not reopened “fully” and “without threat” within the specified timeframe.
