The Japanese destroyer sailed through the strait from early morning to late afternoon, according to a statement by a Chinese military spokesperson, who said naval and air forces were deployed to observe the vessel throughout its passage.

Japan’s Self-Defense Forces declined to comment on the transit. The passage comes against the backdrop of heightened regional tensions over Taiwan, which claims as its territory despite opposition from ’s government.

Beijing considers the Taiwan issue a core national interest and frequently characterizes it as a “red line” in diplomatic relations. It also asserts sovereignty over the strait, a key international shipping route, and has responded strongly to foreign naval movements in the area.

China’s foreign ministry spokesperson said at a press briefing that the transit represented a “display of force” and accused Japan of compounding earlier tensions with what he described as “mistakes upon mistakes.” He added that China had lodged formal diplomatic protests with Tokyo.

Relations between the two countries have deteriorated in recent months, particularly after remarks by Japanese Prime Minister suggesting that a potential Chinese attack on Taiwan could trigger a Japanese military response.

China’s military had previously tracked a foreign naval transit through the strait in February, when an Australian warship sailed the same route, according to state-backed media reports. The latest incident underscores persistent friction over freedom of navigation and sovereignty claims in one of Asia’s most strategically sensitive waterways.

Zelensky said Kyiv had deployed several hundred military specialists to the Middle East following the outbreak of conflict involving Iran, aiming to share its experience in countering drone threats and safeguarding maritime routes.

“Ukrainian military personnel are taking part in consultations on the further operation of the Strait of Hormuz. Safe navigation is a global value; we know this from our experience defending the Black Sea,” Zelensky said in his evening address.

Ukraine has relied on asymmetric tactics and technological innovations during its war with Russia, including the use of naval drones, to counter attempts to restrict access to the Black Sea, a critical corridor for its economy and military operations.

Zelensky said interest in Ukraine’s defense capabilities is expanding beyond Europe, with diplomats receiving requests from Asian countries seeking cooperation on maritime security and related technologies.He did not identify the countries involved but said officials had been instructed to engage on the requests promptly.

Ukraine’s participation in Hormuz-related discussions reflects growing international focus on securing key maritime chokepoints amid ongoing geopolitical tensions affecting global energy and trade flows.

Iran has rejected a U.S. ultimatum to reopen the Strait of Hormuz by a deadline set by former U.S. President Donald Trump, as military strikes intensified and diplomatic efforts led by Pakistan approached what officials described as a critical stage.

With hours remaining before the deadline, a senior Iranian source said Tehran would not reopen the strategic waterway without concessions from Washington that had not been offered. The Strait of Hormuz, a key global energy corridor, has effectively been closed by Iran to most international shipping since late February following joint U.S.-Israeli military actions.

Trump warned that failure to comply would result in large-scale destruction of Iranian infrastructure, including power grids and bridges. In a social media post, he stated that “a whole civilization will die tonight,” framing the moment as a pivotal point in global history.

The remarks drew criticism from legal experts, including a former U.S. State Department adviser now with the International Crisis Group, who said the language could be interpreted as a threat violating international norms.

Military activity escalated across Iran throughout the day. Strikes were reported on transport infrastructure, including railway and highway bridges, as well as an airport and a petrochemical facility. U.S. forces also targeted installations on Kharg Island, which hosts Iran’s primary oil export terminal.

Power outages were reported in parts of Karaj following damage to transmission lines and a substation.Iran signalled a broadening of its response. Officials warned that Gulf states aligned with Washington could face retaliatory strikes on critical infrastructure.

A senior Iranian source said such actions could disrupt electricity and water supplies in desert cities dependent on energy systems.Iran’s Revolutionary Guards issued a statement saying previous restraint had ended and that Tehran would seek to deprive the United States and its regional allies of oil and gas resources.

Iranian authorities also claimed responsibility for attacks on a vessel in the Gulf and on a major Saudi petrochemical facility in Jubail, where international energy companies operate.In parallel, reports emerged of an overnight strike on a synagogue in Tehran, which Iranian officials attributed to Israeli forces.

Footage aired by state media showed debris scattered across the site, including religious texts. Israel’s military did not immediately comment on the incident.Diplomatic efforts led by Pakistan continued amid the escalation.

Iranian officials said mediation attempts were “approaching a critical, sensitive stage,” with Islamabad relaying messages between the two sides. A proposal under discussion included a temporary ceasefire and partial reopening of the strait, with broader negotiations to follow.

However, Iranian sources said Tehran had rejected interim arrangements, insisting instead on a permanent cessation of hostilities, guarantees against future attacks and compensation for damage.Iran’s conditions, as outlined through official channels, also included maintaining control over the strait and introducing a mechanism to regulate transit, potentially involving fees.

Prior to the conflict, the waterway functioned as an open international route through which roughly one-fifth of global oil and liquefied natural gas supplies passed.Despite the intensifying conflict, global markets showed limited reaction, reflecting uncertainty over whether the U.S. would carry out the threatened escalation.

Trump has previously issued similar warnings but later stepped back, citing unspecified progress in talks, claims that Iranian officials have denied.On the ground, residents expressed concern over the prospect of further escalation.

A resident in Isfahan said she hoped the latest threats would not materialise, reflecting broader public anxiety as military actions continued.Iran maintains that any negotiations must follow a halt to U.S. and Israeli strikes and include the lifting of sanctions.

Without such measures, officials indicated that Tehran would continue its current posture, including restrictions on maritime transit through the Strait of Hormuz.

As the deadline approached, neither side signalled a willingness to compromise, raising the risk of further escalation in a conflict that has already disrupted regional stability and global energy flows.

The revised text, circulated by Bahrain, removes earlier provisions that would have allowed the use of force and instead urges states to coordinate “defensive” measures to ensure safe navigation, including escorting commercial vessels.

The vote comes amid more than five weeks of conflict triggered by U.S. and Israeli strikes on Iran in late February, which has led Tehran to largely restrict passage through the strait, a key conduit for global energy supplies, sending oil prices sharply higher.

Diplomats said the watered-down version stands a better chance of adoption but its outcome remains uncertain. A resolution requires at least nine votes in favor and no vetoes from the five permanent members Britain, China, France, Russia and the United States.

Earlier drafts backed by Gulf states and Washington had included language authorizing “all defensive means necessary,” but faced resistance from China and Russia, prompting multiple revisions. China has argued that authorizing force risks escalation and has instead called for efforts to de-escalate the conflict.

Chinese Foreign Minister Wang Yi said Beijing was prepared to work with Russia at the Security Council to help calm tensions in the Middle East, emphasizing that a ceasefire was the fundamental path to resolving the crisis.

Iran has signaled it seeks a lasting end to hostilities but has resisted pressure to reopen the strait, while U.S. President Donald Trump has warned of consequences if Tehran does not reach a deal by a self-imposed deadline.

The latest draft reflects a compromise effort to bridge divisions within the council while addressing growing concerns over disruptions to one of the world’s most critical maritime trade routes.

In a post on Truth Social, Trump warned Tehran to restore access to the strategic shipping lane, which Iran has effectively closed since hostilities intensified. “Tuesday will be Power Plant Day, and Bridge Day, all wrapped up in one, in Iran. There will be nothing like it!!!” he wrote, linking potential military action directly to the disruption of maritime traffic through the strait.

The president’s remarks, delivered in forceful language, underscored the growing pressure on Iran amid ongoing military exchanges. The Strait of Hormuz is a critical artery for global energy supplies, and its closure has heightened concerns over disruptions to oil shipments and broader economic repercussions.

Trump also said he would hold a news conference on Monday in the Oval Office following a U.S. military operation that rescued two American pilots whose aircraft had been downed in Iran. Details of the rescue mission were not elaborated in the statement.

The threat of strikes on infrastructure marks a potential widening of targets beyond military assets, signaling an escalation in U.S. strategy as tensions persist in the region. Iran has not publicly responded to Trump’s latest warning.

The developments come amid continued fighting involving U.S. and Israeli forces and Iranian targets, with both sides reporting damage to infrastructure and military assets over the past month.

The report said any action would likely fall short of a full-scale invasion, instead involving special operations forces and conventional infantry targeting locations such as Kharg Island and coastal areas near the Strait of Hormuz, a critical corridor for global oil shipments.

Washington has already moved thousands of Marines to the Middle East amid the month-long conflict. The first of two contingents arrived on an amphibious assault ship on Friday, according to the U.S. military.

Additional deployments under consideration include forces from the 82nd Airborne Division, alongside approximately 5,000 Marines being repositioned to the region. These reinforcements would add to an estimated 50,000 U.S. troops already stationed across the Middle East, according to media reports.

U.S. Secretary of State Marco Rubio said Washington could achieve its objectives without deploying ground troops but noted that forces were being positioned to give policymakers “maximum” flexibility.

Defense analysts cited in reports said limited operations could aim to secure maritime routes or seize key infrastructure such as Kharg Island, a major hub for Iran’s oil exports.

Military experts have cautioned that even limited ground incursions could lead to prolonged engagement, raising the risk of a broader conflict and increased casualties.

Concerns also persist over the economic implications of instability around the Strait of Hormuz, through which a significant share of global energy supplies passes.

No final decision on ground operations has been announced, and U.S. officials have not publicly confirmed the scope or timing of any potential action.

In a joint statement issued during a ministerial meeting hosted by France, the group said it had emphasized the need to minimize harm to civilian populations, regional partners and essential infrastructure amid intensifying hostilities.

The statement reflected mounting concern among major economies over the humanitarian and systemic risks posed by the conflict.

The ministers underscored that safeguarding non-combatants and public infrastructure remains a priority under international norms, as recent strikes have reportedly affected energy facilities and other civilian-linked assets in the region. They stressed coordination among allies and partners to contain spillover effects.

The G7 highlighted potential disruptions to global supply chains, including energy, fertilizer and broader commercial flows, noting that such shocks could have direct consequences for domestic economies and consumers.

The ministers said efforts were underway to mitigate these risks through coordinated policy responses and international norms.

The statement also reiterated the importance of restoring safe and toll-free maritime navigation through the Strait of Hormuz, a critical chokepoint for global oil shipments.

Any prolonged disruption in the corridor could exacerbate volatility in energy markets and strain international trade routes.

The G7 comprises the United States, United Kingdom, Canada, France, Germany, Italy and Japan, along with the European Union.
