Houthi rebels and the Saudi-led coalition have traded airstrikes in an intensifying exchange of fire that has killed more than 500 people since the Yemeni rebels launched a major offensive last week, with nearly 20,000 civilians forced to flee their homes as the conflict shows no sign of abating.

The overnight salvoes struck multiple regions across Yemen, with Houthi military officials reporting more than 54 coalition airstrikes targeting the provinces of Al-Jawf, Marib, Taiz, Hodeida and Saada in a 12-hour period. The rebel group said it simultaneously launched ballistic missiles and drones at the Saudi cities of Khamis Mushait, Abha and Jizan, claims confirmed by the Saudi-led coalition's spokesman, who did not report any resulting casualties.

Civilians Caught in the Crossfire

For those caught in the fighting, the human toll is stark. "It's a catastrophe, and the attacks are ongoing," said Mohammed Khudairi, one of nearly 20,000 people displaced by the violence, according to the International Organization for Migration. Speaking from a displacement camp of wood-and-straw huts near the Red Sea coastal town of Khokha, he added: "We managed to leave, but others remain trapped there."

The flashpoint areas of Taiz and Hodeida — long contested between Houthi forces and the Saudi-backed government — have seen some of the fiercest clashes. The death toll from a Saudi coalition airstrike on a prison days earlier climbed to 32 dead and seven injured, according to the Houthis' Al-Masirah TV channel, as rescue and recovery operations continued.

Hodeida at the Centre of the Yemen Conflict

Analysis from the Institute for the Study of War suggests the Red Sea port city of Hodeida may be the "ultimate objective" of Saudi-backed ground forces. The institute described the city as "critical to both Houthi civilian and military goods," warning that its loss would represent a significant strategic blow to the rebel movement.

The Houthis' push to seize territory around the Bab al-Mandab strait — the vital gateway to Red Sea shipping lanes — is being driven partly by efforts to tighten their grip on Saudi oil tanker routes. Analysts say this pressure has become more acute following Iran's closure of the Strait of Hormuz, making Red Sea passage critical to Gulf energy exports. Oil prices surged back to $100 a barrel on Wednesday, reflecting the disruption rippling through global energy markets.

The Saudi-led intervention in the Yemeni civil war had reached a relative stalemate before hostilities reignited. The current escalation was triggered in July when the Houthis allowed an Iranian aircraft to land in defiance of Saudi control over Yemeni airspace. The coalition responded by striking the airport — a move the rebels attributed to Saudi Arabia — setting off the chain of events that has now spiralled into a full-scale resumption of fighting.

Regional War Widens the Stakes

The renewed Yemen conflict is unfolding against the broader backdrop of a rapidly expanding Middle Eastern war, which erupted in late February following US-Israeli strikes on Iran. That wider conflict has drawn in Yemen and energy-rich Gulf states, with serious consequences for the global economy. The Houthis had already declared a naval blockade against Saudi Arabia in the Red Sea in July and have continued striking Saudi national infrastructure and energy assets.

Tuesday's Houthi attacks — described as among the heaviest missile and drone barrages against Saudi Arabia in years — set oil facilities ablaze and wounded 73 people. Saudi authorities vowed to retaliate, warning of a firm response to what they characterised as deliberate targeting of civilian infrastructure.

The interplay between Yemen's internal conflict and the broader regional war is raising fears of a return to the full-scale devastation that marked earlier phases of the fighting, with no clear diplomatic off-ramp currently in view.
