Saudi Pipeline Damage Deepens Pressure on Gulf Oil Exports
Saudi Arabia is facing further disruption to its oil-export network after officials said a crucial pipeline damaged in a drone attack would remain largely out of service for several weeks.
The East-West Pipeline carries crude from Saudi Arabia’s oil-producing east towards the Red Sea port of Yanbu, allowing exports to bypass the Strait of Hormuz. Two regional officials told the Associated Press that repairs following the drone attack were expected to leave most of the system unavailable for between three and five weeks. The pipeline has recently been moving roughly 2.6 million to 4 million barrels a day, according to AP.
Its importance has increased sharply during the war with Iran because shipping through Hormuz, normally one of the world’s principal oil corridors, has been heavily restricted. The pipeline offered Saudi Arabia an alternative route to international markets; its disruption now limits that option as Brent crude remains above $100 a barrel.
The pressure extends to Saudi Arabia’s western maritime outlet. Houthi forces have continued their advance in Yemen and consolidated control over strategically located islands in the Red Sea, including Perim at the mouth of the Bab el-Mandeb Strait and the Hanish islands. The waterways around them connect the Red Sea to the Gulf of Aden and form another major route for international shipping.
Saudi Arabia therefore faces restrictions affecting both ends of its principal alternative export network: disruption around Hormuz limits Gulf shipments, damage to the East-West Pipeline constrains the overland alternative, and Houthi territorial gains have increased security concerns around the Red Sea route.
Houthis Launch New Attacks as Hormuz Talks Stall
The Houthis launched another series of attacks against Saudi Arabia as fighting in Yemen intensified.
Reuters reported that missiles and drones were fired at the King Khalid military airbase in Khamis Mushait in southern Saudi Arabia. Saudi authorities said 13 civilians were injured. The Houthis said they had targeted aircraft hangars, radar installations, runways and ammunition depots.
Saudi and Yemeni forces have continued air operations against Houthi positions, but the movement has retained much of the territory captured during its rapid advance along Yemen’s western coastline.
Diplomatic efforts concerning the Strait of Hormuz have simultaneously encountered another setback. A planned meeting in Oman involving Iran and Gulf Arab states was postponed as tensions over Yemen increased. The Guardian reported growing Saudi anger over Houthi advances and attacks on Saudi infrastructure, while Iran said the meeting had been delayed because of developments in Yemen.
The postponement reduced immediate expectations of an agreement that could ease restrictions on Hormuz. Around one-fifth of global oil exports normally move through the strait, while recent attacks on commercial shipping have further complicated its use. Reuters reported that the Houthi offensive and pipeline damage could threaten a substantial additional share of international oil supplies if disruption persists.
Pentagon Review Details Costs and Shortages From Iran War
The United States is also beginning to account publicly for the material costs of its six-month war with Iran.
A Pentagon inspector general review reported significant pressure on American weapons inventories alongside damage to US military facilities and aircraft. According to reporting supplied by CNN and CNBC, the US government has tallied approximately $33.4 billion in costs associated with the conflict.
The review described shortages involving some categories of missiles and other munitions as US forces continue operations across the region. It also documented damage to hundreds of buildings and aircraft at American facilities.
The findings follow months of extensive US operations against Iran and attacks by Iran and allied groups against American and regional targets. Earlier in the conflict, US defence officials acknowledged that American systems could not intercept every Iranian weapon even as the Pentagon maintained that sufficient munitions were available for continuing operations.
President Donald Trump has continued to signal that he expects an eventual agreement with Tehran, but military operations and regional attacks have continued while negotiations over Hormuz remain stalled.
Trump Says Russia and Ukraine Will Avoid Energy Infrastructure
Energy prices have also entered US efforts to manage the war between Russia and Ukraine.
Trump said Russia and Ukraine had agreed to refrain from attacking each other’s energy infrastructure after rising fuel prices placed additional pressure on international markets. He also publicly urged Ukraine to stop striking Russian oil refineries.
Ukraine has repeatedly targeted Russian refineries and other energy installations using long-range drones, seeking to disrupt a sector that provides substantial revenue to Moscow. Russia, meanwhile, has repeatedly attacked Ukrainian electricity, gas and other energy infrastructure during the war.
The latest discussions came as Ukraine said it would pause attacks on Russian energy infrastructure if Moscow did the same.
The issue has acquired additional international significance because disruption in the Middle East has already driven up oil prices. Limiting further damage to Russian and Ukrainian energy facilities could consequently affect fuel supplies beyond the two countries.
Russian attacks nevertheless continued. Poland scrambled military aircraft as Russia launched another large drone operation against Ukraine, including jet-powered drones directed towards Kyiv and other targets.
China Introduces New National-Security Travel Restrictions
China introduced substantially tighter exit and entry restrictions on Tuesday under regulations linking international travel more directly to national and technological security.
Under the rules, Chinese citizens deemed to pose risks to national technology security can be prohibited from leaving the country. Reuters reported that violations connected with export controls or technology import and export legislation can result in exit restrictions lasting from six months to three years.
Foreign nationals can also face entry restrictions lasting between one and five years for providing false information during visa applications.
Restrictions on international travel have previously applied to Chinese government officials and employees with access to sensitive information. Reuters reported that scrutiny had also expanded among civil servants and employees of state-linked companies, particularly regarding foreign contacts.
The new regulations formalise and broaden some of those practices while giving authorities greater powers to restrict travel on national-security grounds. Taiwan has expressed concern about the implications for Taiwanese citizens employed in China’s technology sector.
Sweden Awaits Result of Closely Contested Election
Sweden’s national election remained too close to call as counting continued, with neither political bloc immediately establishing a decisive advantage.
The election followed a campaign dominated by questions including the economy, crime, migration and Sweden’s role in NATO. Prime Minister Ulf Kristersson had made security policy a central issue in the closing stages of the campaign.
Al Jazeera reported that the far right lost ground compared with expectations as votes were counted, leaving the formation of Sweden’s next government unresolved.
Sweden joined NATO in 2024 after abandoning more than two centuries of military non-alignment, and its armed forces have subsequently become increasingly integrated into alliance planning and operations in northern Europe.
Russian Businessman Funded Trump Jr.’s Wedding Celebrations
Separate reporting by ProPublica and The Washington Post disclosed that Russian businessman Umar Kremlev paid hundreds of thousands of dollars towards celebrations surrounding Donald Trump Jr.’s wedding to Bettina Anderson in the Bahamas.
ProPublica reported that Kremlev financed the rental of a private island where a reception was held and guests stayed, as well as other expenses, including a fireworks display. The reporting was based on financial records and interviews with people familiar with the arrangements.
Kremlev heads the International Boxing Association and has longstanding connections in Russia. President Vladimir Putin awarded him Russia’s Order of Friendship earlier this year. The International Boxing Association previously received financing from Gazprom, Russia’s state-controlled energy company, although Kremlev’s representatives told ProPublica that its Gazprom sponsorship had expired.
A spokesperson for Trump Jr. did not dispute that Kremlev paid wedding expenses and described him as a personal friend rather than a business associate. Kremlev’s representatives similarly described the relationship as a friendship and said he had not discussed political matters with Trump Jr.
After publication, Trump Jr. and his wife confirmed that Kremlev had hosted two nights of celebrations, describing the expenditure as a generous wedding gift from a friend. No evidence presented in the reporting established that the payments were made at the direction of the Russian government.
Von der Leyen Changes Plans for Carney Speech
European Commission President Ursula von der Leyen reversed an earlier decision and will attend a major speech by Canadian Prime Minister Mark Carney.
The change places the Commission president among the senior international figures attending an event expected to address Canada’s international relationships and the changing structure of cooperation among Western economies.
Canada and the European Union have been expanding political and economic coordination amid wider changes in transatlantic relations, defence policy and international trade.
Greek Couple Welcomes Daughter From Embryo Frozen for 22 Years
Away from the week’s geopolitical developments, a Greek couple welcomed a daughter born from an embryo that had remained frozen for more than 22 years.
Christina Rapti-Tselepi, 54, gave birth in Athens after using an embryo created more than two decades earlier. The couple decided to proceed following the death of their son in a crash and amid legal time constraints surrounding the embryo’s continued storage.
Their daughter was born weighing 3.49 kilograms. The case drew attention because of the unusually long period between the embryo’s creation and the eventual birth, as well as questions surrounding fertility treatment and long-term embryo preservation.
The story provides a markedly different development from the conflicts and political events dominating the week’s international reporting, while illustrating how advances in assisted reproduction can allow embryos preserved decades earlier to result in successful births.
Tuesday’s developments were again dominated by pressure on Middle Eastern energy routes. Saudi Arabia faces weeks of reduced pipeline capacity as Houthi attacks and territorial gains place additional pressure on the Red Sea corridor, while negotiations concerning Hormuz remain delayed. The Pentagon has meanwhile begun detailing the financial and material costs of the Iran war. Elsewhere, energy infrastructure entered renewed Russia-Ukraine diplomacy, China expanded national-security restrictions on international travel, Sweden continued counting votes after a closely contested election, and new reporting disclosed Russian businessman Umar Kremlev’s financing of celebrations surrounding Donald Trump Jr.’s wedding.
