Assessment
The formal military deployment of Turkish and Pakistani forces to Saudi Arabia alongside heavy coalition air campaigns and ground battles confirms the return of full-scale internationalized warfare in Yemen.
BOTTOM LINE // The conflict expands into open interstate war with allied foreign military deployments to Saudi Arabia and intense air and ground offensives across Yemen.
ISW assesses that Houthi control of al Turbah will likely severely constrain Yemeni government-aligned forces' ability to reinforce and resupply front-line positions across Taiz Governorate. Institute for the Study of War · 4 Oct 2026Iran Update October 4 2026

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 85.7/100 as of 1 January 1970 (mass 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 85.7/100 — mass 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.
