British Foreign Secretary Yvette Cooper said London “strongly” supports including Lebanon in the ceasefire, citing humanitarian concerns following the latest Israeli attacks. “We do want to see the ceasefire extended to Lebanon,” she told Sky News, adding that the scale of displacement and civilian impact was deeply troubling.

Lebanon’s health ministry said at least 203 people were killed and more than 1,000 wounded in strikes on Wednesday, marking one of the deadliest days in the current phase of the conflict between Israel and Hezbollah.

The calls were echoed by Kaja Kallas, the European Union’s top diplomat, who said Israeli actions were placing the ceasefire under “severe strain” and that the truce should be broadened to include Lebanon.

France’s foreign minister Jean-Noel Barrot also condemned the strikes, describing them as “unacceptable.”U.S. President Donald Trump had earlier announced a two-week ceasefire with Iran to enable negotiations after weeks of conflict that disrupted global energy markets and heightened geopolitical risk.

However, U.S. Vice President JD Vance said Lebanon was not part of the agreement, warning that any collapse in talks over the issue would be Tehran’s responsibility.

Iran signaled growing frustration, with parliament speaker Mohammad Bagher Ghalibaf stating that continued Israeli strikes in Lebanon, alongside other concerns, had undermined the basis for negotiations and made further talks “unreasonable.”

The United Nations High Commissioner for Human Rights, Volker Turk, described the scale of casualties in Lebanon as “horrific,” particularly after strikes in densely populated areas of Beirut that reportedly occurred without prior warning.

The escalation comes ahead of planned talks between U.S. and Iranian officials in Pakistan, where mediators have urged all parties to maintain restraint. Pakistan’s Prime Minister Shehbaz Sharif called for adherence to the ceasefire to allow diplomacy to proceed.

Tensions remain high over the Strait of Hormuz, a critical global energy corridor, as uncertainty persists over maritime security and oil flows following recent disruptions.

Meanwhile, Hezbollah said it had resumed rocket fire toward Israel in response to continued strikes, signaling a potential widening of hostilities despite ongoing diplomatic efforts.

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.

According to the report, some officials in the White House view Ghalibaf as a pragmatic figure who could engage in negotiations with Washington as the conflict with Iran enters a new phase.

The report said discussions remain preliminary and are being conducted quietly within the administration. Ghalibaf is seen by certain policymakers as a figure capable of navigating Iran’s political structure while maintaining enough authority to enter into talks with the United States.

There was no immediate comment from the White House on the report.Context of rising tensionsThe deliberations come amid escalating hostilities between the United States and Iran, including ongoing military exchanges and heightened regional instability.

The conflict has drawn in multiple actors across the Middle East, increasing the risk of broader escalation.Uncertainty over Tehran’s stanceIt remains unclear how such considerations would be received in Tehran.

Iranian officials have publicly rejected claims of engagement with Washington, with Ghalibaf himself recently denying that any negotiations with the United States have taken place.

We’re going after the IRGC,” Netanyahu said during the visit, adding that Israel would pursue its leadership, installations and economic assets.

The missile strike on Arad injured at least 59 people, according to Israeli medics, while nearby Dimona widely believed to be near Israel’s nuclear research facilities also sustained significant damage from a direct hit.

Rescue teams were deployed to affected neighbourhoods, where buildings were partially destroyed and debris scattered across residential areas. Authorities described the incident as a mass casualty event.

Netanyahu urged residents to strictly follow instructions from Israel’s Home Front Command and seek shelter during air raid sirens, describing the current situation as one in which “the entire home front is a frontline.

”He said adherence to safety protocols was critical to preventing casualties during continued missile barrages.

Iranian officials, including parliament speaker Mohammad Bagher Ghalibaf, have described recent strikes as marking a new operational phase in the conflict, as Iranian missiles penetrated Israeli air defences in areas previously considered highly protected.

The exchange of attacks comes amid a wider regional escalation involving Iranian-backed groups, including Hezbollah, and follows strikes on key sites in both countries as the conflict enters its fourth week.

Trump issued the warning in a social media post on Saturday, saying Washington would “obliterate” Iranian power facilities if the strategic waterway remained closed. The strait, a critical conduit for global oil flows, has been effectively shut amid the ongoing hostilities.

Iran’s military command, Khatam al-Anbiya, said any attack on its fuel and energy infrastructure would trigger strikes on U.S. and Israeli assets, including critical civilian-linked systems.

The statement, carried by state media, underscored a widening scope of potential targets beyond conventional military sites.

Iranian officials also indicated that access through the Strait of Hormuz would be restricted, with passage permitted selectively, reflecting Tehran’s control over the route during the conflict.

The escalation coincided with renewed Iranian missile barrages on Israel, including strikes near the southern cities of Dimona and Arad, close to the Negev Desert nuclear research area.

Israeli authorities said dozens were injured and residential buildings sustained heavy damage.Israeli Prime Minister Benjamin Netanyahu said the impact in Arad caused extensive destruction but no fatalities, while urging adherence to air raid warnings. Israel’s military acknowledged that some missiles were not intercepted, marking a breach in air defence coverage in the area.

Iran’s parliament speaker Mohammad Bagher Ghalibaf said the strikes indicated a shift to a new operational phase in the conflict.

The conflict has extended beyond Iran and Israel, with Hezbollah claiming responsibility for a deadly strike in northern Israel, while Gulf states reported drone and missile activity targeting energy infrastructure.

Iran also targeted the joint UK-U.S. military facility at Diego Garcia in the Indian Ocean, though officials said the strike was unsuccessful. Military assessments cited in reports suggested the possibility of longer-range capabilities or alternative launch methods, though no confirmation was provided by Tehran.

The disruption to shipping through the Strait of Hormuz has halted most tanker traffic, contributing to supply constraints and rising global energy prices. Countries including the United Arab Emirates, Britain, Germany, France and Japan have expressed readiness to support efforts to restore safe navigation through the waterway.

U.S. Central Command said earlier that strikes on Iranian coastal facilities had degraded Tehran’s ability to target vessels in the strait. Additional U.S. naval assets and personnel are being deployed to the region as part of ongoing operations.

Casualties have mounted across multiple theatres, with Iran reporting more than 1,500 deaths, while Israel, the United States and Gulf states have also recorded military and civilian losses.
