SANAA/RIYADH — Yemen's Iran-backed Houthi rebels killed at least 30 to 58 government troops in missile and drone strikes Thursday, in what regional reporting has called one of the deadliest days of Yemen's civil war in four years. The attacks struck government military camps in the Hadramout and Marib provinces, hitting forces that gathered for a morning training exercise — a detail that officials say drove the casualty count higher than it otherwise would have been.
The strikes didn't stop there. By Friday morning, Yemeni and Al Jazeera reporting said the Houthis had launched a fresh round of missile and drone strikes on the same two provinces — some accounts put the figure at roughly a dozen additional launches, though exact counts vary by source and appear to blend attempted strikes with government claims of intercepted drones. Separately, a senior Saudi military spokesman said a Houthi strike on Saudi Arabia's southern Najran province wounded 11 civilians — Saudi, Yemeni, Egyptian and Pakistani nationals among them, including a 4-year-old child who suffered second-degree burns.
This is no longer a contained skirmish. It's the sharpest escalation of Yemen's civil war since the Saudi-led coalition and the Houthis settled into a de facto truce in 2022 — and it's unfolding directly inside the wider US-Israel war against Iran that began at the end of February.
The chain of events is not hard to trace. On July 13, Yemen's internationally recognized government struck Sanaa's airport to block an Iranian aircraft it accused of using civilian cover to ferry equipment to the Houthis. The Houthis retaliated with missiles at Saudi Arabia, then imposed a maritime blockade on July 20 disrupting oil shipments and striking Saudi state oil giant Aramco's facilities in Jizan and Yanbu. Saudi Arabia responded by forming an international naval coalition to guard the Red Sea, with roughly a dozen countries signing on so far.
What makes this moment more dangerous than the prior four years of intermittent strikes is what intelligence agencies are now saying about who's actually directing it. A senior Saudi official told Reuters that intelligence from the United States, Saudi Arabia and other Middle Eastern governments warns the Houthis and Iraqi armed groups — under the direct supervision of Iran's Islamic Revolutionary Guard Corps — may be preparing coordinated strikes on Saudi energy infrastructure, ports and airports. Analysts tracking the region say Iran's role has shifted from quiet backing to explicit endorsement: Tehran is now publicly defending Houthi demands rather than working through intermediaries, extending its leverage from the Strait of Hormuz to a second maritime chokepoint, the Bab al-Mandeb strait.
That second chokepoint matters enormously to the global economy. Roughly 30% of global container traffic and 12-15% of overall global trade moves through the Red Sea corridor the Houthis are now threatening to choke off, mirroring the playbook Iran has already run at Hormuz. Markets reacted almost immediately — Brent crude jumped more than $3 a barrel Thursday into Friday, settling above $83, after topping $100 earlier this year amid the broader Iran conflict.
Not every actor on the Iran-aligned side wants the temperature to keep rising. The head of Iraq's Badr Organization, part of the Iran-backed Popular Mobilization Forces, has urged Iraqi militias to hold off on retaliatory strikes against Saudi Arabia for now — a notable pump of the brakes after joint Saudi-US strikes on PMF positions in Iraq late last month killed more than 20 people. It's a sign the escalation isn't unanimous even among Tehran's own network of allied forces.
Still, the honest read from people who track this conflict for a living isn't reassuring. The International Crisis Group's senior Yemen analyst, Ahmed Nagi, has said a window to contain the escalation still exists — but only if US-Iran de-escalation removes one of the key drivers behind the Houthi campaign, and if Saudi Arabia and the Houthis can strike understandings on flashpoints like Sanaa airport and Hodeidah's ports. His own assessment of where things stand right now: the indicators point toward further escalation, not containment.
For Washington, that's the story to watch closely over the coming days — not just as a Middle East regional conflict, but as a second front, alongside Hormuz, in Iran's broader campaign to weaponize the world's shipping lanes against the United States and its allies.
