Marib: the ceasefire nobody has formally ended
Yemen has been at war since 2014, when the Houthi movement seized the capital and a Saudi-led coalition intervened on behalf of the recognised government. A United Nations truce in April 2022 largely stopped the big battles. It was never a peace agreement, and it has never been formally abandoned.
Over two days in August 2026 the Houthis put ballistic missiles and drones into military camps in Marib and Hadramawt, and then into displacement camps and residential streets in Marib city. Dozens of government troops were killed. The UN envoy called it the greatest risk of renewed large-scale war since that truce, while the strikes were still landing.

Missile and drone strikes hit military camps in Marib and Hadramawt provinces. Government sources report at least thirty troops killed - among the deadliest single escalations in months.
Friday - the city
Ballistic missiles and drones strike displacement camps and residential neighbourhoods in Marib city, killing two and wounding fourteen according to local authorities cited by the state news agency.
The stated target
The Houthis say they struck Saudi-backed forces, depots, vehicles and military equipment at the Sahn al-Jinn camp. The recognised government describes strikes on displacement camps and residential areas. Neither account has been independently verified.
The envoy speaks while it is still happening
The UN Special Envoy for Yemen states that these attacks, together with renewed attacks on commercial shipping in the Red Sea and Gulf of Aden, have left Yemen at its greatest risk of renewed large-scale conflict since the April 2022 truce. He urges maximum restraint.
The response, and the next escalation
Government forces attack on several fronts in reply. Two days later the movement strikes Mokha port and the Jazan refinery, extending the exchange to the coast and across the Saudi border.
How the war started
The Houthi movement, an Iran-aligned force from Yemen's north, seized the capital Sanaa and drove out the internationally recognised government. A Saudi-led coalition intervened in 2015 to restore it. The country has been divided since: the Houthis hold Sanaa and much of the north-west, and the recognised government - now the Presidential Leadership Council - operates from Aden.
A truce, not a peace
The United Nations brokered a two-month truce that was renewed and then largely held in practice even after it formally lapsed. It substantially reduced front-line fighting for four years. It settled nothing. No party renounced its objectives, no political settlement followed, and no mechanism existed to declare it over.
The government's principal stronghold
Marib is the recognised government's main position in northern Yemen, sits over the country's gas reserves, and hosts one of the largest displaced populations in the world - people who fled the fighting elsewhere and have nowhere further to go. Hadramawt, in the east near the Saudi border, is the government's other principal base. Striking both at once is an attempt to take the war back to where it stopped.
The unravelling begins at sea
The Houthis declared a naval blockade on Saudi Arabia in the Red Sea and began striking Saudi energy infrastructure, citing an alleged siege of Houthi-held areas that Riyadh denies.
These strikes are the land component of a single escalation. The maritime campaign gets the international attention because it touches shipping; the ground campaign is where the casualties are. Reading them separately understates both.
The 2022 truce has failed in practice without failing on paper
The agreement that quietened Yemen for four years was a pause in fighting, not a settlement, and nothing in it provided a way to declare it finished. So it has not been. What has happened instead is two days of missile and drone strikes on the recognised government's two principal strongholds, a government counter-offensive on several fronts, and a UN envoy publicly warning of the greatest risk of large-scale war since 2022. The framework still exists and it no longer describes anything. Any organisation still planning against it is planning against a document rather than a situation.
Displacement camps in the target area is the humanitarian finding
Marib hosts one of the largest displaced populations in Yemen, and strikes were reported on displacement camps and residential neighbourhoods. Whether those were aim points or effects, the population concerned has no protection, no alternative location and no means of leaving. The humanitarian consequence is the same either way.
The claims of both sides are unverifiable and should be recorded as claims
The movement says it struck Saudi-backed forces and depots. The government says displacement camps and homes were hit. Reuters stated it could not verify either. The disciplined entry is both accounts and the impasse, and it is the same problem as at Mokha two days later.
The land and maritime campaigns are one escalation and should be briefed together
The UN envoy explicitly linked the Marib and Hadramawt strikes to renewed attacks on shipping. It is likely that further ground escalation drives further maritime action and vice versa, because each is presented as justification for the other.
The trajectory is toward wider conflict, and the regional dimension is growing
These strikes sit alongside claimed attacks on Saudi territory, a declared blockade, and a new regional defence agreement involving Saudi Arabia. It is highly likely that fighting between the Houthis and the recognised government continues at this intensity, and likely that further external actors are drawn in as the maritime consequences accumulate.
Set this beside Najran, where the same movement made a claim nobody could verify and Riyadh said nothing. Here the casualties are counted by both sides and the UN envoy is speaking publicly. The same actor, one week apart, producing an unverifiable claim and an undeniable escalation - which is why claims from this source have to be assessed one at a time rather than by reputation.
- Stop planning against the truce. Any organisation with people, contracts or cargo exposed to Yemen should be working from the current tempo of strikes rather than from the 2022 framework.
- Treat Marib as a high-intensity environment with a large displaced civilian population. Humanitarian and commercial actors need movement plans, shelter arrangements and communications that assume ballistic and drone attack on the city itself.
- Brief the land and maritime pictures together. A shipping risk assessment that does not track the ground campaign will not anticipate the next maritime escalation, because the two drive each other.
- Record claims from all parties as claims. Where neither side can be verified, a ledger that records both accounts is more useful six months later than one that picked a side.
- Expect casualty figures to move and to disagree. The counts here differ between government sources, local authorities and agencies. Decisions built on early figures should say which figures they used.
- Watch the UN envoy's language as an indicator. A public statement that a conflict is at its greatest risk in four years is the clearest available signal of institutional assessment, and it is free to monitor.

Compiled from open-source reporting for professional security discussion. Casualty figures derive from government sources and local authorities cited by the state news agency and differ between accounts; they were still moving at time of writing. The Houthi movement states it struck military forces, depots and equipment; the recognised government describes strikes on displacement camps and residential neighbourhoods. Reuters reported it could not independently verify the claims of either side, and this report does not attempt to resolve them. Details may be revised. This is a protective-security lessons-learned assessment, not an operational account.
