← WW3 RISK TRACKER / THEATER: Yemen War & Houthi Attacks
Saudi – Houthis conflict
- Houthi missile and drone strikes on Mokha port killed four people, injured twelve, and forced a complete halt to port operations.
- Houthi forces launched six ballistic missiles targeting civilian displacement camps in Marib governorate.
- Yemeni government forces executed 181 operations against Houthi positions in Taiz, reporting over 200 Houthi fighters killed or wounded.
- Saudi authorities issued a security alert for Jazan province along the southern border with Yemen following cross-border military activity.
- White House officials transmitted direct warning messages to Ansar Allah leadership regarding continued Red Sea and port attacks.
Yemeni government forces and Ansar Allah engaged in intense ground warfare across Marib and Taiz while Houthi missile strikes halted operations at Mokha port. The theater faces severe internal combat and renewed cross-border disruption along the Saudi frontier.
On 16 August 2026, Houthi forces launched six missiles into displacement camps in Marib and conducted drone and missile strikes against Mokha port, killing four people, injuring twelve, and causing $16 million in facility damage. Yemeni army spokesmen reported conducting 181 strikes against Houthi positions in Taiz governorate during a 24-hour period, claiming over 200 Houthi casualties. Meanwhile, Saudi Arabia issued a security warning for Jazan province in response to heightened cross-border launch activity.
Diplomatic channels yielded no de-escalation as international pressure focused on deterrence. White House officials sent explicit warning messages to Houthi leadership demanding an immediate end to Red Sea and port strikes. United Nations mediation efforts remained frozen, with no progress on activating the December 2023 roadmap or executing the May 2026 detainee release framework.
The current surge follows the resumption of Houthi maritime attacks in July 2026 and the breakdown of regional restraint. The closure of Mokha port severely restricts commercial shipping and fuel imports into southwestern Yemen, exacerbating local economic strain. Military mobilization around Taiz and Marib indicates both sides are seeking territorial advantage while peace talks remain suspended.
Frontline fighting in Marib and coastal strikes against maritime infrastructure will likely persist in the short term. Assessment: Continued Houthi attacks on commercial ports and urban displacement camps risk triggering broader regional responses and further military escalation across western Yemen.

COMMON QUESTIONS
Is there a war in Yemen?
Not a declared war between states. The armed confrontation is between the Houthi movement and the Saudi-led coalition and the Yemeni government, and it reaches shipping in the Red Sea and the Bab al-Mandab strait. Fighting has continued through repeated truces without a settlement. Legally a non-international armed conflict — the Houthis against Yemen's government — internationalized by Saudi and Emirati involvement. The index reads 72/100 as of 1 January 1970 (full-scale war); above 50 it grades the fighting itself rather than the risk of it.
How dangerous is the Saudi and Houthis situation right now?
The index reads 72/100 — full-scale war. The scale is anchored on 22 historical episodes from 1914 to 2005, so the number means the same thing from one theater to the next. It is a measurement of what is reported, not a forecast.
How is the Saudi and Houthis risk index calculated?
By fixed formula from open-source reporting: events are extracted and graded by how well evidenced they are, scored across weighted factors, and the model never picks the number. How the index works, and what it does not measure, is explained at wwiii.report/methodology.
How often is this updated?
Every day. The report is rebuilt from that day's reporting and the index re-judged from it, and a fall is published only once the evidence confirms it.

One 0–100 scale for the whole conflict. 0–49 is escalation before war; 50–100 is active war and how far it has gone.
50 is not a threshold the number can cross on its own. Which side a theater sits on is decided by whether verified belligerents are fighting there, so war onset always moves the score up across 50 — the number never declares a war by climbing.
It is a stage, not a probability: 42 is not a 42% chance of war. Below 50 it grades movement toward war, above 50 the war itself.
Why it moved, under the chart, names what changed in the latest move: the day’s readings — strikes, casualties, talks — and, when the conflict’s stage was re-judged, what was graded differently and the events behind it. Open it for the detail.
Re-judged from open reporting by fixed formula — the model never picks a number — and a fall publishes only once the evidence confirms it. A dot on the line is a day the stage itself moved. How it is made →
Direction — which way the week pushed. Severity — where the index sits. Connections — how much of the rest a shock here reaches. Cascade — that reach combined with how ready this theater is to go off.
The index reads the state of the conflict, not the volume of news. Each run grades the factors listed below against fixed rubrics, and the score follows by formula.
So a dramatic headline moves nothing unless it changes a grade. A theater already graded for recurring incursions absorbs one more without moving — it is priced in.
Open How this was measured for every grade, its movement since the last run, and the events behind it. Full construction →
A different measurement from the score above, from a different source. This line counts how much of the world's news reports conflict between these two states, against their own long-run normal: 100 is normal, 200 is twice the usual level.
It is computed mechanically from the GDELT Project's open event stream every 15 minutes and never touches the assessed index above — when both move together, that agreement is the signal. A day with too few events shows no reading rather than a guess. Click the chart for the full history.
