Saudi Arabia's civil defence authorities said the threat has passed in Riyadh shortly after issuing an alert, as hostilities between the kingdom and Yemen's Houthi militia intensify.

Multiple explosions were heard in the Saudi capital on Tuesday, as the military coalition said it had intercepted a ballistic missile launched by Houthi militia towards Riyadh.

Residents received a text-message alert on their mobile phones instructing them to take shelter due to an "aerial threat".

"Air defences intercepted and destroyed a ballistic missile launched by the terrorist Houthi militia toward Riyadh," the Saudi-led coalition posted on X.

Saudi Civil Defence issued an alert warning of potential danger in Riyadh. The alert did not specify the threat.

Earlier, the Saudi-led coalition said it had intercepted and destroyed a ballistic missile fired by Yemen’s Houthi militia towards southern Saudi Arabia.

The coalition is fighting the Houthi militia in Yemen.

The Saudi-led coalition said it intercepted and destroyed a ballistic missile that Yemen’s Houthi militia fired towards southern Saudi Arabia.

The Houthi militia seized Yemen’s capital, Sanaa, in 2014.

The coalition intervened the following year in support of Yemen’s internationally recognised government.

Iraq will temporarily close the Mandali border crossing with Iran from Friday “to complete technical requirements”, the Iraqi state news agency reported.

Iraqi Foreign Minister Fuad Hussein said on Sunday that the US Treasury had urged Baghdad to keep just two crossings with Iran open to increase economic pressure on Tehran.

Hussein warned that closing most crossings would hurt Iraq’s own economy.

Qatari Prime Minister and Foreign Minister Sheikh Mohammed bin Abdulrahman Al Thani held separate talks with US President Donald Trump and Vice President JD Vance, making “good progress” on Iran, Al Jazeera reported, citing a source familiar with the talks.

The source gave no details on what progress was made or whether the talks produced any agreement.

Earlier Monday, an unnamed Iranian official told the semi-official Fars News Agency that reports of talks to reopen the Strait of Hormuz in exchange for the release of $8 billion in frozen Iranian assets were false.

Kentucky congressman Thomas Massie introduces eight articles of impeachment, accusing Hegseth of illegally waging war against Iran without congressional authorisation and abusing his powers as Pentagon chief.

A Republican lawmaker has moved to impeach US Defense Secretary Pete Hegseth over the US war on Iran, setting up a potentially explosive vote in Congress just days after President Donald Trump's party suffered a crushing midterm defeat.

Kentucky congressman Thomas Massie introduced eight articles of impeachment on Monday, accusing Hegseth of illegally waging war against Iran without congressional authorisation and abusing his powers as Pentagon chief.

The Republican-controlled House could vote as early as Wednesday, with some lawmakers from Trump's party signaling that they might join Democrats in supporting the charges.

Impeachment would not automatically remove Hegseth from office.

That would require a trial and conviction by a two-thirds majority in the Senate — a far higher hurdle, even after Democrats take control of the chamber in January.

Iran's parliament speaker has accused Israel of trying to draw the US into a prolonged war with Iran, warning that future US presidents would struggle to extricate the country from the conflict.

"Israelis are working overtime to drag the US into an endless war with Iran, a quagmire that no president, now or in the future, Republican or Democrat, could escape," Mohammad Bagher Ghalibaf wrote on US social media company X.

"Unless Washington drops the ‘Israel First’ mindset, America and its allies are headed straight for a dark age," he added.

US President Donald Trump has told Reuters news agency in a brief phone interview that Qatar and Saudi Arabia are eager for a peaceful solution on the Iran conflict but the US is ready to resume military strikes if necessary.

Trump, who met Qatar's prime minister earlier on Monday, said "Qatar would rather see a peaceful solution" but "we're ready to go anytime we want" with attacks.

Fighting between Yemeni government forces and the Houthi militias escalated across six provinces, with the government reporting dozens of Houthi militants killed or wounded and nine civilians injured in shelling and gunfire it blamed on the group.

Clashes and strikes were reported in Taiz, Lahj, Marib, Al-Jawf, Hajjah, and Hudaydah. Neither side announced any territorial gains.

The government’s Nation Shield Forces said in a statement on social media platform X that its units launched a “large-scale surprise attack” on Houthi positions and fortifications on the Al-Muhawala front in southwestern Lahj province.
