It's been a week since Yemen's Iran-backed Houthi rebels stormed down the Red Sea coast, extending their reach to a key maritime chokepoint and threatening Saudi Arabia's oil exports.

The Houthis' biggest land grab in years reignited Yemen's 12-year civil war and pushed up global fuel prices. It also gave Iran another potential source of leverage as the United States has started to loosen Tehran's grip on the Strait of Hormuz, on the other side of the Arabian Peninsula.

The deadly collapse of a multistory building in Gaza has drawn new attention to the hardships facing Palestinians there nearly a year after a ceasefire between Israel and Hamas promised to kickstart reconstruction.

But as talks faltered, plans for rebuilding stalled. Israel bars entry of almost all construction materials, making even repairs difficult. Many residents have since moved back into some of the hundreds of thousands of homes damaged by the war despite the risk of weakened foundations and unstable walls suddenly giving way.

Hundreds of thousands of Iranians rallied Friday in a government-organized show of defiance after months of war, pledging their readiness to take up arms in the biggest such demonstration since the United States and Israel attacked in February.

Iran's government has sought to rally the people and stress national unity, even as the economy worsens under a U.S. naval blockade of Iranian ports and new U.S. sanctions meant to increase Tehran's economic pain.

A tanker was struck in the Strait of Hormuz on Friday, causing a fire that was extinguished, according to the United Kingdom Maritime Trade Operations (UKMTO).

"The CSO of a vessel has reported a tanker being hit by an unknown projectile, causing a fire onboard which has since been extinguished," the maritime monitor said, adding that the crew were safe, although the environmental impact of the attack was "unconfirmed".

Lebanon's judiciary has accused 14 Lebanese and Syrians, including a Hezbollah member and an Assad-era Syria officer, of forming and training groups to launch attacks in Syria, a judicial official said Thursday.

Earlier this month, Lebanese authorities arrested a group including a former Syrian intelligence officer and several accomplices who allegedly planned attacks against the forces of Syria's new government and received training from Iran-backed Hezbollah. The group has denied the allegation.

Saudi Arabia's civil defense agency on Thursday said one person was killed when shrapnel from an intercepted Houthi drone crashed down over Taif governorate that lies east of Mecca.

"The fall of shrapnel from a downed drone in Taif governorate resulted in one death, two injuries, and material damage to several buildings and vehicles," the agency said in a statement posted on social media, adding that the person killed was a Yemeni national.

Human rights experts commissioned by the U.N.'s top human rights body say they have found "reasonable grounds" to believe the United States committed war crimes in two strikes in Iran, including on a school in the southern city of Minab.

The international fact-finding mission on Iran says the findings center on a pair of airstrikes that killed at least 178 civilians, including women and children.

The Palestinian Authority on Thursday slammed a decision by the United States to refuse visas for its officials to attend the U.N. General Assembly in New York next week, a move which includes President Mahmoud Abbas.

In a statement, the Palestinian foreign ministry called it "an unjustified measure that runs counter to efforts to rebuild trust, develop Palestinian–U.S. relations, and create the necessary political climate for implementing the two-state solution and achieving peace and stability".

Saudi Arabia is running low on missile interceptors and has turned to regional and Western allies for assistance as its standoff with Houthi rebels in Yemen drags on, two regional officials said Wednesday.

The officials said the Saudis have asked France, Britain, Pakistan and Egypt to deploy air-defense support to the region to help defend against missiles and drones fired by Houthis and other Iran-backed groups.

As Houthi rebels closed in, Eshraq Abdel Gelil and her husband fled their home, walking through the mountains before catching a ride to a nearby city. Four months pregnant, she feared another miscarriage.

They are among more than 125,000 people who have fled as the Iran-backed rebels have advanced down the Red Sea coast to a key maritime chokepoint. The offensive, linked to the wider Iran war, has threatened Saudi oil exports, pushed up global fuel prices and rattled markets.
