A Turkish diplomatic source said representatives from Azerbaijan, Bahrain, Egypt, Jordan, Kuwait, Pakistan, Qatar, Syria, Turkey and the United Arab Emirates would attend.

The meeting comes amid limited signs of de-escalation nearly three weeks into the U.S.-Israeli war with Iran, which has disrupted the region and affected global energy supplies. The conflict has heightened concerns over broader instability across the Middle East.

Hakan Fidan is expected to stress the need for a negotiated and peaceful resolution, warning that a prolonged conflict could inflict lasting damage on ties between regional countries, the Turkish source said. He is also expected to visit additional countries following the Riyadh talks.

Turkey, a member of the NATO and a neighbour of Iran, had sought to mediate between Tehran and United States before the war began. Ankara has since condemned U.S. and Israeli strikes on Iran as violations of international law, while also criticising Iranian attacks on Gulf states as unacceptable.

The Riyadh meeting is expected to focus on coordinated diplomatic efforts to contain the conflict and mitigate its economic and security repercussions across the region.

Speaking to reporters at the White House during a St. Patrick’s Day visit by Irish Prime Minister Micheál Martin, Trump said allied governments had expressed support for U.S. and Israeli actions but were unwilling to provide direct military assistance.

Trump noted that several allied countries had indicated they had no immediate plans to deploy naval forces to help secure the Strait of Hormuz, a critical maritime corridor through which roughly one-fifth of global oil supplies pass.

The comments followed calls by the U.S. administration for international support to maintain shipping access after Iran responded to joint U.S.-Israeli strikes with drones, missiles and naval mines that have effectively hindered tanker traffic.

Despite the criticism, Trump said he had “nothing currently in mind” when asked whether Washington would retaliate against allies for their stance.

“I think NATO is making a very foolish mistake,” Trump said. “Everyone agrees with us, but they don’t want to help.”

Earlier in the day, Trump struck a different tone on social media, stating that the United States no longer needed NATO assistance due to what he described as “Military Success” in the ongoing conflict, now in its third week.

In that statement, he also singled out non-NATO partners Japan, Australia and South Korea, without elaborating on their roles.

Trump has previously raised the possibility of withdrawing the United States from NATO, though he did not revisit that position in his latest remarks.

The standoff over the Strait of Hormuz has heightened concerns about global energy supplies, as disruptions in the narrow waterway can have immediate implications for oil markets and shipping routes.

The reluctance of NATO allies to engage militarily underscores divisions within the alliance over involvement in the conflict, even as diplomatic backing for U.S. actions appears to remain intact.

Takaichi will be the first major ally to hold face-to-face talks with Trump since he urged Japan and other partners to send naval vessels to escort tankers through the strategically vital waterway, which has been largely disrupted by Iran during the conflict.

“The biggest risk is that Trump publicly presses her for security commitments that she can’t deliver on,” said David Boling of the Asia Group consultancy in Tokyo, a former U.S. trade negotiator with Japan.

The Strait of Hormuz handles roughly a fifth of global energy supplies, with about 90% of Japan’s crude oil imports passing through it, underscoring Tokyo’s exposure to the crisis.

Japanese officials said Takaichi had initially planned to steer discussions toward concerns over China’s regional posture ahead of a delayed visit, but shifting U.S. priorities have forced a focus on Iran and maritime security.

Japan has received no formal request from Washington, Takaichi told parliament earlier this week, adding that the government was assessing possible responses within the constraints of its pacifist constitution.

Several U.S. allies, including Germany, Italy and Spain, have ruled out joining a Gulf mission. Kaja Kallas said on Tuesday that no country was prepared to risk personnel in the conflict zone.

Public sentiment in Japan also remains cautious. Fewer than 10% of respondents support U.S. and Israeli strikes on Iran, according to a poll by the Asahi newspaper.

Trump has alternated between criticising allies for their reluctance and downplaying their necessity, singling out countries like Japan that rely on U.S. security guarantees while depending heavily on Middle Eastern oil flows.

Tokyo has historically limited its role in Middle East operations to logistical and intelligence support. Analysts say deploying Japanese vessels into an active conflict zone would face significant legal and political hurdles.

“It has turned into a discussion that shakes the very foundations of the Japan–U.S. security alliance,” said Kazuhiro Maeshima, a politics professor at Sophia University in Tokyo.

Tusk told a government meeting that Warsaw “does not plan any expedition to Iran,” adding that the decision was understood by the United States and other allies.He said the position applied across Poland’s land, air and naval forces.

Tusk emphasized that Poland’s military posture remains oriented toward its immediate security environment, particularly in light of the ongoing conflict linked to Ukraine.

He noted that strengthening capabilities along Poland’s eastern flank continues to take precedence.Securing the Baltic Sea remains a central pillar of Poland’s defense strategy, he added, underscoring Warsaw’s focus on regional deterrence and stability rather than participation in operations farther afield.

The remarks come after Trump called on allied nations to contribute to efforts to safeguard shipping through the Strait of Hormuz, a critical artery for global energy supplies that has faced attacks and threats attributed to Iranian forces during the third week of a U.S.-Israeli conflict with Iran.

Several U.S. allies, including Germany, Spain and Italy, have also indicated they have no immediate plans to deploy naval assets to the region, signaling broader reluctance within Europe to expand military involvement.

Poland’s stance reflects a wider recalibration among European states balancing alliance commitments with domestic security priorities, particularly as military resources remain tied to reinforcing defenses closer to home.

No injuries were reported and no arrests had been made as of Friday morning, police said, adding that the fire had been extinguished.

Police said the blaze began at about 3:40 a.m. local time.“Around 3:40 a.m., a fire was started at the synagogue,” Rotterdam police said in a post on X, noting that the flames burned briefly before being brought under control.

Authorities have appealed for witnesses or anyone with relevant information to come forward as investigators work to determine the circumstances surrounding the incident.

The fire comes days after another synagogue about 200 kilometres away in Belgium was struck by an explosion earlier this week, which authorities described as an antisemitic attack.

That incident caused property damage but no injuries.Separately, in the U.S. state of Michigan, a Lebanon-born American citizen drove a truck into a synagogue and its preschool before being shot dead, according to authorities.

Authorities and community groups have warned of rising risks to Jewish institutions worldwide following U.S. and Israeli airstrikes on Iran and Tehran’s subsequent response.

The Rotterdam investigation is ongoing as police seek to establish the motive and identify those responsible.

The U.N. refugee agency said the estimate was based on preliminary assessments of the number of households forced to leave their homes during the fighting. The conflict has triggered large-scale internal displacement across affected areas as residents move to safer locations within the country.

“This figure is likely to continue rising as hostilities persist, marking a worrying escalation in humanitarian needs,” UNHCR said in a statement.

The agency said the 3.2 million figure reflects early data gathered from humanitarian monitoring and may change as more information becomes available from affected regions.

UNHCR noted that displacement inside Iran has intensified since the outbreak of the conflict at the end of February, with families relocating from areas affected by military activity.

The agency warned that the growing number of displaced people is increasing pressure on humanitarian services and assistance networks.

UNHCR said the continuing hostilities could further expand the scale of internal displacement and humanitarian needs in the coming weeks as assessments continue.

The military said naval ships were deployed to accompany commercial vessels to ensure the uninterrupted flow of national energy supplies and maintain the security of sea lines of communication, which are critical for the country’s economy.

The escort operation was launched to counter what the military described as “multidimensional threats” to national shipping and maritime commerce. Pakistan relies heavily on sea routes for trade, with the armed forces noting that roughly 90 percent of the country’s commerce moves by sea.

Officials said maintaining secure maritime corridors was essential to ensuring the continuity of energy imports and broader economic stability.

Pakistan, which shares a border with Iran in its southwest, depends significantly on oil and gas supplies from Gulf producers.

Amid concerns about supply disruptions linked to the regional conflict, the government raised domestic fuel prices by about 20 percent last week, triggering long lines at petrol stations across the country.

Prime Minister Shehbaz Sharif on Monday announced a series of austerity measures aimed at conserving fuel, including closing government offices one day a week and directing half of public-sector staff to work from home.

Authorities also ordered schools to shut for two weeks as part of the effort to reduce fuel consumption and limit transport demand.

The military said naval forces remained fully prepared to respond to emerging maritime security challenges but did not provide further details about the scope or duration of the escort operations.

The move comes as heightened tensions across the Gulf region raise concerns among energy importers about potential disruptions to shipping routes and oil supplies.

Her remarks came as Seoul and Washington proceeded with their annual joint military exercises, which the two allies say are designed to strengthen defensive readiness against potential threats from North Korea.

Kim Yo Jong described the military exercises as provocative and warned they could undermine security in the region. Statements from North Korean officials have frequently portrayed joint U.S.-South Korean military activities as rehearsals for invasion.

The criticism reflects longstanding opposition from Pyongyang to the annual exercises, which typically involve large-scale troop deployments and coordinated operations between the two militaries.

Officials in South Korea and the United States maintain that the drills are defensive in nature and aimed at ensuring readiness and coordination between allied forces.

The exercises form a central component of the long-standing military alliance between the two countries, which maintains a substantial U.S. troop presence on the Korean Peninsula.

Analysts say North Korea’s leadership remains focused on maintaining strong deterrence capabilities amid shifting geopolitical tensions. One analyst said Pyongyang is determined not to face the same fate as Iran amid the ongoing conflict involving the United States and its allies.

The comments come as regional tensions remain elevated amid global security concerns and ongoing military activity across several geopolitical flashpoints.

The conversation came as fighting involving the United States, Israel and Iran continues to expand across the region, raising concerns among international leaders about broader instability and disruptions to global energy markets.

Carney and the Qatari emir emphasized the importance of strengthening diplomatic efforts to contain the conflict and prevent further escalation, according to the statement from the Canadian leader’s office.

The two leaders also condemned Iranian missile and drone attacks targeting Qatar. Carney expressed Canada’s solidarity with Qatar following the strikes.

“In accordance with international law, the leaders called for an immediate end to attacks on civilians and civilian infrastructure that only serve to destabilise the region and worsen the global economic and energy situation,” the statement said.

Hostilities escalated after the United States and Israel began military strikes against Iran on Feb. 28. Iran subsequently launched retaliatory attacks against Israel and several Gulf states hosting U.S. military bases.

U.S. President Donald Trump has offered varying objectives and timelines for the military campaign. The conflict has resulted in significant casualties inside Iran, including the death of Iran’s Supreme Leader Ali Khamenei, according to the information provided.

At least 1,230 people have been killed in Iran since the start of the conflict, according to the humanitarian organisation Iranian Red Crescent Society.

Among them were 175 schoolgirls and staff killed in a missile strike on a primary school in southern Iran, the group said.

Iran’s military has also reported that more than 100 people were killed when a U.S. submarine sank an Iranian warship off the coast of Sri Lanka last week.

Israeli authorities say 11 civilians have been killed in Israel since the conflict began, while the U.S. military has reported that seven American service members have died.

The ministry said the deployments were made “in the context of the latest developments in our region,” adding that additional measures could be taken depending on how the situation evolves.

European powers have stepped up military activity on the divided Mediterranean island since a drone struck Britain’s RAF Akrotiri air base in Cyprus last week. Security officials believe the drone was launched by Hezbollah, the Iran-backed Lebanese militant group.

The Turkish defence ministry said six F-16 jets along with air defence systems had been positioned in northern Cyprus, which Ankara recognises as an independent state.

“As a result of the evaluations to be made depending on the developments, additional measures will continue to be taken if necessary,” the ministry said in a statement.

The island of Cyprus has been divided for decades between the internationally recognised government in the south and the Turkish Cypriot administration in the north. Ankara does not recognise the Greek Cypriot government, which is a member of the European Union.

Nikos Christodoulides, the Greek Cypriot president, said the Turkish deployments were a response to recent European statements asserting that the island’s security falls under the responsibility of the European Union.Speaking to Greek newspaper Kathimerini, he described Turkey as an “occupying power” in Cyprus.

Tufan Erhurman, leader of the Turkish Cypriot community, criticised the remarks and said the focus should instead be on ensuring security for the entire island and both communities.

Omer Celik, spokesman for Turkish President Recep Tayyip Erdogan’s ruling Justice and Development Party, said the deployment was not aimed at any country but intended to strengthen security and maintain the balance of power on the island.“But we must add this: other steps may come too, whether it is air defence systems, drone centres,”

The latest move follows a regional security incident last week when NATO defences intercepted a ballistic missile fired from Iran that entered Turkish airspace. Ankara warned Tehran on Saturday against launching further missiles toward its territory.
