← WW3 RISK TRACKER / THEATER: Yemen War & Houthi Attacks
Saudi – Houthis conflict
- Houthi missile and drone attacks forced the suspension of operations at Yemen's Mokha port after causing eight deaths and $16 million in damages.
- Houthi ballistic missiles struck residential areas and military positions in Marib city, causing multiple civilian and troop casualties.
- Yemeni government forces launched retaliatory drone strikes against Houthi positions in Taiz governorate, killing three fighters.
- Saudi Arabia initiated efforts to organize an updated maritime security framework following repeated coastal and Red Sea strikes.
- Heavy ground clashes and artillery exchanges between Houthi forces and government troops spread across Marib, Taiz, and Red Sea sectors.
The conflict between Ansar Allah and Yemeni government forces backed by Saudi Arabia intensified as Houthi ballistic missile and drone strikes forced the complete suspension of operations at Mokha port and targeted Marib city. Over 25 strikes hit the coastal facility at Mokha, killing eight people, injuring security personnel, and inflicting an estimated $16 million in commercial and structural damage.
In Marib governorate, Houthi forces launched multiple ballistic missiles into urban residential quarters and military facilities, causing civilian deaths and prompting Yemeni army counter-barrages. In Taiz governorate, Yemeni government troops deployed attack drones against Houthi frontline positions, killing three Houthi fighters and wounding local commanders. The dual offensives against Mokha and Marib represent the heaviest combined air and artillery bombardment across western Yemen since mid-2026.
Diplomatic efforts by the United Nations Special Envoy remain stalled as both Ansar Allah and the internationally recognized Presidential Leadership Council mobilize forces along contested axes. Saudi Arabia moved to assemble a targeted maritime coalition to safeguard commercial shipping near the Bab el-Mandeb strait following the shutdown of Mokha port. Neither side has engaged in formal bilateral peace negotiations since the escalation surrounding Sana'a airport and Red Sea maritime corridors in July 2026.
The destruction at Mokha port restricts humanitarian and commercial maritime access to southern and western Yemen, compounding economic pressure on government-controlled territories. The renewed shelling of Marib threatens critical energy infrastructure and oilfields that supply regional domestic power grids. These combined operations dismantle the post-2022 relative calm and elevate the risk of full-scale regional confrontation involving Red Sea shipping lanes and Saudi border sectors.
The complete disruption of key Red Sea port operations alongside widespread missile strikes on Marib signals a transition back toward open multi-front military confrontation inside Yemen. Assessment: The theater is likely to experience sustained multi-axis military operations and further disruption to regional maritime shipping over the coming weeks.

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 45/100 as of 1 January 1970 (limited 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 45/100 — limited 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.
