Authorities in Russia’s Leningrad region confirmed that additional mobile fire units would be deployed to protect strategic facilities, including the major Baltic ports of and , which have faced repeated attacks in recent weeks. Governor said the units would include reservists serving on voluntary contracts, tasked specifically with countering unmanned aerial vehicle (UAV) threats.

Kyiv has described the strikes as retaliatory measures against Russia’s sustained aerial bombardment of Ukrainian cities. Ukrainian forces have increasingly targeted Russia’s energy infrastructure, aiming to disrupt export revenues that remain a key source of funding for Moscow’s war effort.

The attacks have had a measurable impact on Russia’s oil logistics. According to data cited by the Center for Research on Energy and Clean Air, oil shipments from Ust-Luga and Primorsk fell by roughly half in the week following a March 23 drone strike compared to the same period a year earlier.

Despite these disruptions, Russia’s oil revenues have shown resilience. The reported that Russian oil export earnings nearly doubled to $19 billion in March, reflecting elevated global prices amid broader geopolitical tensions, including conflict in the Middle East.
President had previously authorized the use of reservists to guard energy infrastructure under legislation signed last year, as Ukraine expanded its use of long-range drones to strike deeper into Russian territory.

The intensifying exchange of strikes underscores a shift in the conflict toward targeting economic assets, with both sides seeking to degrade the other’s capacity to sustain prolonged military operations.

The announcement came a day after talks in Pakistan ended without agreement, underscoring persistent divisions over terms to end a conflict launched on Feb. 28 by the United States and Israel. The blockade is aimed at pressuring Iran to reopen the Strait of Hormuz and accept a broader settlement addressing its nuclear and missile programs, as well as its regional activities.

Trump indicated that diplomatic channels remain open, saying Iran had reached out to explore a possible resolution. “We’ve been called by the right people … and they want to work a deal,” he told reporters outside the White House.Iran signaled conditional openness to negotiations.

Judiciary chief Gholam Hossein Mohseni Ejei said discussions must proceed on the basis of “principles and logic,” while other officials warned that Tehran would respond if the situation escalates.The blockade drew sharp reactions from Iran, which threatened countermeasures targeting ports across the Arabian Gulf and Gulf of Oman, raising the risk that the two-week ceasefire declared earlier could collapse before its April 22 expiry.

At the core of the dispute remain differences over Iran’s nuclear program and control of the Strait of Hormuz, a critical global energy corridor through which roughly one-fifth of the world’s oil supply typically passes. Its closure has already disrupted markets and driven up oil prices.

U.S. Vice President JD Vance, who led the American delegation in the recent talks, said Iran had not provided assurances it would refrain from pursuing nuclear weapons capability. Tehran has long denied such intentions while defending its right to civilian nuclear development, including uranium enrichment.

Iran’s negotiating position, articulated by Parliament Speaker Mohammad Bagher Qalibaf, emphasized sovereignty over the strait, an end to hostilities, and compensation for wartime damage.

Iranian officials also dismissed the blockade as exaggerated, with parliamentary spokesperson Ebrahim Rezaei describing it as “more bluffing than reality.”Pakistan has indicated it may facilitate further dialogue, with Foreign Minister Ishaq Dar expressing willingness to host another round of talks, though no timeline has been confirmed.

Both sides have maintained firm public positions, with Trump warning that any Iranian attempt to challenge the blockade would be met with force, while Iranian foreign ministry spokesperson Esmaeil Baqaei said the measure risked further destabilizing the global economy.

In a post on social media, Trump said U.S. naval forces would block “any and all ships” attempting to enter or leave the waterway, which carries roughly 20% of global oil supplies and is central to international energy markets.

He added that the Navy had been instructed to “seek and interdict every vessel in international waters” that had paid a toll to Iran, describing such payments as illegal and warning that affected ships would not be granted safe passage.

The announcement came shortly after U.S. officials ended negotiations with Iran in Pakistan without reaching an agreement, prompting Washington to escalate efforts to curtail Tehran’s economic leverage derived from control over the strategic shipping lane.

Trump said Iran’s nuclear ambitions remained a key obstacle to resolving the conflict and signaled readiness for further military action. “At an appropriate moment, we are fully ‘locked and loaded,’” he wrote, adding that U.S. forces would “finish” the remaining aspects of the war.

The Strait of Hormuz is a critical chokepoint for global energy supplies, and any disruption to shipping through the narrow passage has the potential to impact oil prices and international trade flows.

No immediate response from Iranian authorities was reported.

Leiter said Israel had agreed to begin “formal peace negotiations” with the Lebanese government, despite the absence of diplomatic relations between the two countries.

The talks are scheduled to open Tuesday at the U.S. State Department following contacts between Israeli and Lebanese representatives.“Israel refused to discuss a ceasefire with the Hezbollah terrorist organization, which continues to attack Israel and is the main obstacle to peace between the two countries,” Leiter said in a statement.

The position contrasts with calls from Lebanese authorities and the administration of U.S. President Donald Trump for a pause in hostilities ahead of negotiations. A report citing sources familiar with the discussions said Washington and Beirut had urged Israel to halt its attacks before talks begin.

Israel launched an intensified military campaign, including airstrikes and a ground offensive in Lebanon, after Hezbollah fired rockets into northern Israel in early March, in a move linked to broader regional tensions involving Iran.

Israeli officials have maintained that the ongoing conflict in Lebanon is separate from the ceasefire arrangement between the United States and Iran, with negotiations between those two countries set to take place in Islamabad.

In the absence of a ceasefire, discussions in Washington are expected to focus on measures Israel wants the Lebanese government to take, particularly regarding efforts to curb Hezbollah’s activities.

Lebanese authorities say the conflict has killed more than 1,950 people in recent weeks, including over 350 fatalities reported on Wednesday alone, marking one of the deadliest days since the escalation began.

The strike targeted a government building in the southern city of Nabatieh, part of a broader Israeli aerial campaign across multiple areasvin southern Lebanon. Hezbollah said it carried out 31 attacks in response, including strikes on northern Israel and Israeli ground forces operating inside Lebanese territory.

The group also claimed responsibility for an attack on a naval base in the Israeli port city of Ashdod, approximately 145 km from the Lebanese border, signaling an expansion in the range of hostilities.The escalation comes ahead of talks scheduled to begin Tuesday in Washington, D.C., to be mediated by U.S. officials.

The office of Lebanese President Joseph Aoun said the discussions were agreed upon following contacts between Israeli, Lebanese and U.S. diplomats, reiterating Beirut’s position that negotiations should take place under a ceasefire.

However, Israeli Ambassador to the United States Yechiel Leiter described the upcoming meeting as “formal peace negotiations” and said a ceasefire would not be part of the agenda, highlighting a divergence in positions.A Lebanese government official familiar with the matter said a halt in hostilities remained a key condition for Beirut’s participation, speaking on condition of anonymity.

The latest round of fighting began after Hezbollah launched rockets toward northern Israel on March 2 in support of Iran, prompting Israel to initiate an expanded air campaign and ground operations in southern Lebanon.Lebanon’s Health Ministry said at least 1,953 people have been killed in Israeli strikes since the escalation began.

On Wednesday alone, about 100 strikes across the country including densely populated areas of Beirut killed at least 303 people, marking the deadliest day in the current conflict.Concerns have also grown over the safety of medical facilities. The World Health Organization has called for the protection of Rafik Hariri University Hospital after Israeli evacuation warnings covered surrounding areas, including the Jnah neighborhood.

Health officials said they had received assurances the hospital would not be targeted, though staff remain at risk amid ongoing strikes.Emergency responders continue to search for victims trapped under rubble in Beirut and other affected areas as hostilities persist.

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.

A proposal brokered by Pakistan called for an immediate ceasefire and reopening of the strait, followed by negotiations on a broader settlement within weeks, according to a source familiar with the plan. Iran declined the offer, instead outlining conditions including sanctions relief, regional de-escalation, and reconstruction measures, state media reported.

Trump reiterated threats to target Iranian infrastructure if Tehran failed to meet his demands by the deadline, warning that bridges and power plants could be destroyed. He said the United States could “take out” the country if an agreement was not reached.Fighting continued across the region.

The Israeli military said it carried out airstrikes on Iranian government infrastructure in Tehran and other areas, while intercepting missiles launched from Iran. Saudi Arabia reported intercepting ballistic missiles over its eastern region, with debris falling near energy facilities, and issued public safety alerts alongside the United Arab Emirates and Bahrain.

Iran’s envoy to the United Nations condemned the U.S. threats as a violation of international law, while senior Iranian officials dismissed Trump’s warnings. Authorities also called for civilian demonstrations to protect infrastructure sites.

A synagogue in central Tehran was damaged by a projectile, according to local media, as the conflict widened beyond military targets.Global oil markets remained under pressure, with prices hovering around $110 per barrel amid uncertainty over the reopening of the Strait of Hormuz, a conduit for roughly a fifth of the world’s oil and gas supply.

The continued disruption has raised concerns about inflation and energy security worldwide.The conflict, which began after U.S. and Israeli strikes on Iran in late February, has led to thousands of casualties across the region.

A U.S. fighter jet was also downed last week, underscoring the escalating risks for Washington as the crisis deepens.

The King Fahd Causeway Authority said movements across the 25-kilometer bridge, the only road link between Saudi Arabia and Bahrain, were halted in response to security alerts issued through the kingdom’s early warning systems.

Saudi Arabia’s defense ministry said it had intercepted ballistic missiles aimed at the Eastern Province, without providing further details on the origin or scale of the attack.

The causeway is a critical transport and economic corridor linking Bahrain host to the U.S. Navy’s Fifth Fleet to the Arabian Peninsula, and its closure underscores rising regional risks tied to the ongoing conflict involving Iran.

The development comes as Donald Trump has set a deadline for Iran to reopen the Strait of Hormuz and agree to a ceasefire, warning of potential strikes on Iranian infrastructure, including bridges and power facilities, if demands are not met.

Regional tensions have intensified in recent days, with missile interceptions reported across Gulf states and increased security measures implemented to protect critical infrastructure and civilian areas.

The Israel Defense Forces said it had identified incoming missiles and was responding to the threat, confirming that defensive systems were operating to intercept them.

The exchange followed Israeli strikes described as a “wave” of air attacks on Iran, marking a further escalation in hostilities between the two countries.

No immediate details were provided on damage or casualties from the missile launches or interceptions.

The latest developments come amid intensifying cross-border attacks as the conflict between Israel and Iran continues to expand, raising concerns over broader regional escalation.

The strikes, part of an expanded military campaign since March 2 after Hezbollah joined the regional conflict alongside Iran, hit Beirut and areas in southern Lebanon. The Lebanese health ministry said a strike in Beirut’s Jnah district killed at least five people and wounded 52.

Additional attacks included a strike on an apartment building in Ain Saadeh east of Beirut, where three people were killed, including Lebanese Forces official Pierre Mouawad and his wife, according to the state-run National News Agency.

In the southern town of Kfar Hatta, seven people, including a four-year-old girl, were killed, the ministry said.Israel’s military did not immediately comment on the specific strikes. Chief of staff Lieutenant General Eyal Zamir visited troops in southern Lebanon on Sunday and said operations against Hezbollah would intensify.

Hezbollah said it had fired a cruise missile at an Israeli warship off the coast, but the Israeli military said it was not aware of such an attack.The escalation prompted the closure of the Masnaa crossing, Lebanon’s main land route to Syria. Israel had warned it would strike the crossing, alleging it was being used by Hezbollah to transfer military equipment.

Lebanese and Syrian officials said the crossing, a key civilian and trade artery, was evacuated and shut as a precaution.The United Nations Interim Force in Lebanon warned that exchanges of fire near its positions could risk further escalation.Since the conflict expanded, Israeli strikes in Lebanon have killed more than 1,400 people and displaced over one million, according to Lebanese authorities.

A strike in Jnah landed about 100 meters from Rafik Hariri University Hospital, causing damage and panic among patients. Hospital officials said they received dozens of casualties, while witnesses described explosions and falling debris in the area.Residents reported repeated strikes without warning.

Nancy Hassan, a local resident who previously lost her daughter in earlier fighting, said the campaigns had again hit her neighborhood.

Lebanese President Joseph Aoun called for negotiations to prevent further destruction, particularly in southern regions where Israeli ground forces have advanced.
