The Iran conflict continues to drive tensions across the Middle East, with US President Donald Trump extending sanctions on Iran and planning to put Tehran’s nuclear ambitions at the centre of his UN diplomacy next week. Saudi Arabia has issued and later lifted danger alerts in Riyadh and Al Kharj, while the Houthis reported 26 Saudi strikes in Yemen over the past 24 hours. Iran also claimed it struck an oil tanker in the Strait of Hormuz, as shipping traffic through the Bab el-Mandeb remains disrupted. Meanwhile, a UN-mandated fact-finding mission said there were reasonable grounds to believe the US may have committed war crimes in two February strikes on Iran.

Saudi Civil Defence: Danger has passed in Riyadh, Al Kharj

Saudi Arabia’s Civil Defence has said the danger has passed in Riyadh city and Al Kharj Governorate after earlier alerts were issued.

In separate posts, the General Directorate of Saudi Civil Defence urged residents to continue following safety instructions and avoid gathering or filming.

Residents were advised to call 911 in case of an emergency.

Explosions heard in Saudi capital Riyadh

Explosions were heard in the Saudi capital Riyadh early Saturday. Local residents received air defence alerts via mobile apps.

The Saudi Directorate of Civil Defence later issued a statement on X saying the danger has passed in Riyadh and Al Kharj and urged residents to continue following its instructions and avoid gathering or filming.

Earlier it had warned: "An alert has been issued by the National Early Warning Platform for Emergency Cases in Al-Kharj Governorate to warn of a danger."

Shipping 'must not become targets of geopolitical tensions': India

India, whose shipping and nationals have suffered collateral damage in the Strait of Hormuz conflict, has reiterated its call for respecting international law and said commercial maritime traffic "must not become targets of geopolitical tensions".

"Navigational rights must not be subject to coercion, threats, unlawful restrictions or arbitrary interference", India's Permanent Representative P Harish told the Security Council.

"India is a major maritime nation, and we strongly support a free, open, secure and rules-based maritime domain", he said.

Harish spoke at an informal Council meeting convened by Bahrain to discuss the maritime security environment under the Arria-Formula, named for Venezuelan diplomat Diego Arria, who initiated such gatherings while presiding over the body in 1992.

India has also suffered economically from the blocking of the Strait of Hormuz, which disrupted the supply of oil and gas, as well as the steep rise in global petroleum prices.

The disruption in the Gulf and West Asia "has implications across regions of the globe, particularly in terms of energy and food security", Harish said.

US touts $1bn UN cuts ahead of Trump speech

The Trump administration says it has secured more than $1 billion in United Nations budget cuts, alongside reductions in headquarters staff and peacekeepers, as President Donald Trump prepares to address the General Assembly next week.

A senior US official told reporters that 3,000 headquarters positions were being trimmed and more than 25 per cent of peacekeepers worldwide were being sent home.

The administration presented the reductions as part of an effort to narrow the UN's work and concentrate its resources on peace and security. The briefing did not provide a breakdown of the savings, affected posts or peacekeeping missions.

"Over a billion dollars has now been cut out of the UN budget," the official said.

The official described the cuts as the first in the organisation's 80-year history and credited Trump and the secretary of state with driving the changes. That historical claim was not accompanied by supporting figures during the briefing.

"We call it having the UN on a diet," the official said.

The administration's argument is that the organisation has taken on too many responsibilities and should concentrate on resolving conflicts.

Trump signs Graham sanctions law targeting Russia, Iran

US President Donald Trump has signed the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026 into law, expanding sanctions on Russia and extending existing US sanctions on Iran, the White House said.

The law gives the president authority to impose tariffs of up to 100% on imports from countries that meet specified criteria linked to purchases of Russian crude oil or natural gas, or efforts to evade sanctions.

India, China face potential tariff exposure

The legislation targets Russian officials, financial institutions, defence networks and the country’s so-called “shadow fleet” of vessels used to transport energy while avoiding Western restrictions.

It also extends the Iran Sanctions Act for five years.

The law does not automatically impose a 100% tariff on any country. Instead, it allows the president to impose targeted duties of up to 100% on the five largest importers of Russian crude oil or natural gas and countries found to be facilitating sanctions evasion.

The measure could have implications for India and China, among the major buyers of Russian crude, by creating a statutory route for potential tariffs on imports from countries that continue specified purchases of Russian energy.

The president can waive certain measures under specified conditions, including by certifying to Congress that a waiver is in the national interest.

Iran claims it struck an oil tanker in the Strait of Hormuz

Iran said it struck the Togo-flagged oil tanker Trend over what it described as an "illegal attempt" to pass through the Strait of Hormuz on Thursday night, according to the state broadcaster, which cited the Revolutionary Guard Corps.

The Guard's navy warned that vessels attempting to pass through the strait without authorization would face "destruction," the broadcaster said. Tehran has asserted control over much of the waterway since the US and Israel launched the war on Feb. 28.

Separately, the United Kingdom Maritime Trade Operations, which alerts about attacks or military operations, said another tanker was struck Wednesday by an "unknown projectile" while transiting out of the strait, with the crew reported safe. No other details were available.

Trump signs bill authorising broad new sanctions to squeeze Russia

US President Donald Trump signed a bill Friday authorising new sanctions designed to pressure Russia over its war in Ukraine, shortly after it received congressional approval this week.

The legislation takes aim at Russia's energy and defense sectors, alongside President Vladimir Putin and other senior officials.

It also targets Moscow's so-called shadow fleet of tankers used to evade Western sanctions, and allows Trump the authority to impose tariffs of up to 100 percent on major buyers of Russian oil and gas.

This could potentially cover China and India, and furthers efforts to cut off revenue financing Moscow's war.

The Republican-led House of Representatives passed the package by a 262-159 vote on Wednesday.

The bill would also target companies and foreign actors supporting Russia's military, and extend sanctions involving Iran.

Iran war's cost grows to $43.6b in new US military estimate

The US military's price tag for the Iran war has grown to $43.6 billion as of Sept. 3, according to a new estimate provided this week to lawmakers.

The figure from US Central Command, which oversees operations in the Middle East, offers the most up-to-date cost for the conflict since it was launched by the United States and Israel on Feb. 28. A Congressional Budget Office report released Tuesday said the war had cost $38 billion through Aug. 1 and will continue to rack up expenses of around $3 billion a month depending on the conflict's intensity.

The new breakdown, seen by The Associated Press and reported earlier by Bloomberg and Punchbowl News, also showed the continued use of expensive munitions by American forces. Weapons costs jumped by more than $6 billion in just over a month, from $21.7 billion listed in the CBO report to $28.1 billion in US Central Command's estimate.

CNN, MS NOW, Politico banned from White House: Trump

President Donald Trump said that he was banning CNN, MSNOW and Politico from the White House due to what he called unfavorable coverage, and threatened that more such prohibitions of media outlets could follow.

Meanwhile, in-person voting for this year's midterm elections is underway in Virginia, ushering in the final six weeks for Americans to decide which party they trust to lead Congress at a time of a cost-of-living crisis, a prolonged war in Iran and other pressing issues. Voters in Idaho, Minnesota and South Dakota, can cast absentee ballots in person.

And a top official at the U.S. Postal Service has said the agency has stopped work on developing a controversial computer system that was central to Trump's effort to limit mail voting after the Supreme Court rejected his executive order this week.

Houthis say Saudi Arabia launched 26 strikes in Yemen over 24 hours

Yemen's Houthis said that Saudi Arabia had launched 26 strikes against areas under their control in the past 24 hours, as the pro-Iran group and Yemen's Riyadh-backed government clash in the country's revived civil war.

The group said that the number of Saudi strikes on its positions had reached 300 over the last week, saying they targeted areas across Houthi-held Yemen.

US Iran war death toll higher than Pentagon has disclosed

The actual number of American service members killed in the conflict with Iran is higher than what the Pentagon has made public, according to Washington Post reporting relayed by Reuters. The Post's account draws on six US officials with knowledge of the Defense Department's internal records on casualties. Per five of those sources, the true fatality figure stands at 22 or more — four higher than what currently appears in the Pentagon's public tracking database.
