SANAA/RIYADH — Yemen’s fragile calm is rapidly collapsing as fighting between Houthi forces and Saudi-backed forces intensifies, with the conflict spilling directly across the border and triggering repeated emergency alerts in southern Saudi Arabia.
The latest escalation has become one of the most serious flare-ups since the 2022 truce largely halted years of open warfare between the Houthis and the Saudi-led coalition.
Houthi attacks hit Saudi cities
On Tuesday, Houthi forces launched a major wave of missile and drone attacks against southern Saudi Arabia, targeting cities including Abha, Khamis Mushait, Jizan and Najran.
Saudi authorities said at least 73 people were wounded, including women and children. The attacks also sparked fires at energy and utility facilities, temporarily disrupting operations at some sites.
The Houthis claimed responsibility, saying they had targeted Saudi energy infrastructure and military facilities in retaliation for Saudi-backed military operations in Yemen.
Saudi Arabia has vowed to respond.
Emergency alerts repeatedly sounded
The threat has remained active even after the initial attacks.
On Thursday, Saudi civil defence authorities issued an emergency alert in Khamis Mushait for the fourth time within 24 hours before later declaring that the danger had passed. The repeated alerts underscored concerns that the attacks could continue.
Saudi officials have accused the Houthis of continuing to target national infrastructure with ballistic missiles and drones, while promising further measures to protect the kingdom.
The fighting inside Yemen is getting worse
The escalation is not limited to Saudi territory.
Saudi-backed Yemeni government forces have launched a counteroffensive against Houthi positions in western Yemen, with fighting reported around Taiz and Hodeidah and other strategic areas.
The renewed ground fighting has reportedly killed and displaced civilians while threatening to push Yemen back toward a much broader war. More than 21,000 people were displaced and 194 killed between August 23 and September 5, according to figures cited by the Associated Press from the World Health Organization.
A deadly strike on a Houthi-run prison in Yemen’s al-Jawf province has further intensified the confrontation. The death toll from the strike rose to at least 23, according to AP.
A dangerous threat to the Red Sea
The renewed conflict matters far beyond Yemen and Saudi Arabia.
The Houthis have been attempting to strengthen their position around the western coast of Yemen and the Bab al-Mandeb Strait, one of the world’s most important maritime chokepoints.
Any prolonged fighting that disrupts the strait could affect shipping between the Red Sea and the Gulf of Aden, putting additional pressure on global trade and energy markets.
The danger is particularly serious because the wider region is already experiencing disruption around the Strait of Hormuz, another critical route for global energy shipments. Brent crude has moved above $100 a barrel amid the broader regional instability.
The truce is now under serious pressure
The 2022 ceasefire dramatically reduced the intensity of the Saudi-Houthi war, but it never produced a permanent political settlement.
Now, the latest fighting threatens to undo years of de-escalation.
The United Nations has warned that the Houthi attacks on Saudi Arabia could widen the conflict and undermine efforts to find a political solution.
For Yemen’s civilians, the prospect is especially grim.
After more than a decade of war, millions remain dependent on humanitarian assistance. A return to sustained Saudi-Houthi warfare could deepen displacement, damage already fragile infrastructure and make humanitarian access even more difficult.
A wider Middle East conflict is taking shape
The timing of the escalation is also significant.
The renewed Saudi-Houthi confrontation is unfolding alongside the wider conflict involving Iran, the United States and Israel, increasing the possibility that Yemen could once again become a major front in a much broader regional war.
The Houthis’ alignment with Iran has made Yemen a strategic pressure point against Saudi Arabia, while Riyadh has strong incentives to prevent the conflict from threatening its cities, oil infrastructure and economic transformation plans.
What began as another round of fighting in Yemen could therefore become something much larger.
For now, the warning sirens in southern Saudi Arabia are a reminder that the Yemen war is far from over — and the consequences could extend well beyond the Arabian Peninsula.
