The UN's humanitarian coordination office is reporting simultaneous emergencies across three theatres, with the most acute pressure in Yemen's Taiz, where the encirclement of the city has severed supply lines and pushed the health system toward collapse. In Afghanistan, funding shortfalls are forcing clinics to scale back or close, while in Western Sahara the UN has begun the orderly liquidation of its long-running peacekeeping mission.

Taiz: a city cut off from care

All roads into Taiz are now closed because of the fighting, and no commercial supplies are getting through, according to the UN's aid coordination office, OCHA. The consequence is a healthcare emergency measured in six figures.

Nearly a quarter of a million people have lost access to essential healthcare due to lack of supplies. That population includes more than 186,000 children under the age of five and 23,000 pregnant women.

Twelve hospitals are at risk of closing, even as demand for healthcare rises because of worsening living conditions. The disease signal is already alarming: in just one week, more than 1,400 cases of acute diarrhoea and suspected cholera were reported. Cholera mostly spreads through contaminated water, a transmission route that becomes more dangerous precisely when clean supply and sanitation systems break down.

Displacement deepens nationwide

The Taiz crisis sits inside a broader displacement emergency. Nearly 300,000 people have been forced from their homes since the beginning of August, OCHA reports. Before the latest escalation this summer, 5.2 million people out of a total population of around 42 million were already displaced.

OCHA says it has provided around 254,000 displaced people with food, hygiene supplies and emergency cash assistance. That response is meaningful in scale but partial against the pace of new displacement, and it does not address the supply blockade that is starving Taiz's hospitals of the materials they need to function.

Why the health numbers matter

The composition of the affected population is the story. Children under five and pregnant women are the two groups most dependent on routine and emergency care, and both are disproportionately represented among those cut off. When a dozen hospitals sit on the edge of closure, the risk is not only cholera mortality but the collapse of maternal care, treatment for chronic conditions and routine childhood illness — a slow-motion toll that outlasts the headline outbreak.

Afghanistan: funding cuts close the door on care

In Afghanistan, UN aid teams are warning that vital health centres are being forced to scale back or close because of funding cuts to humanitarian services.

OCHA said remote communities — such as those in Badakhshan province in the country's far northeast — face long and dangerous journeys to reach care. The geography compounds the funding problem: when a facility closes in a remote district, the alternative is not a nearby clinic but a difficult and risky trip.

“There are needs, particularly severe and extreme needs that are on the increase in many parts of the country,” said OCHA spokesperson Olga Cherevko. She described a “worrying” increase in malnutrition at Kishim District Hospital in Badakhshan, noting the hospital lacked the resources needed to provide adequate support to patients who depend on it.

“Often there is simply nowhere else left to turn,” she stressed.

Afghanistan remains one of the world's largest humanitarian crises, with nearly 22 million people needing assistance. The UN agency said in a recent update that food is available but too expensive for millions of Afghans — a distinction that matters for how the crisis is framed and addressed. This is not purely a production failure but a purchasing-power failure, which means market-based food assistance and cash programming carry particular weight.

The funding arithmetic behind the closures

The Afghan case illustrates how humanitarian funding cuts translate directly into service withdrawal. Health centres are among the most cost-sensitive parts of an aid operation: staffing, medicines and cold-chain supplies must be sustained continuously, and a gap in funding does not pause demand. Cherevko's warning about malnutrition at Kishim District Hospital points to the downstream effect, where reduced capacity meets rising need in a province already defined by distance from care.

Western Sahara: MINURSO winds down in phases

The UN will repatriate some 160 military observers and close 13 facilities and team sites in Western Sahara as it winds down its peacekeeping mission there, MINURSO, UN Spokesperson Stéphane Dujarric said on Monday.

The mission ceased operations after Security Council members did not renew its mandate, and its liquidation period began on Sunday.

A smaller team reporting to the UN Department of Operational Support will oversee the “orderly and environmentally responsible” closure and handover of the sites, in phases. Around 180 civilian and affiliated personnel will also leave.

The administrative workload is substantial: UN property and equipment will be disposed of or transferred, communications and logistics systems taken down, mission records archived and local contracts closed. The UN will keep administrative, financial and security oversight throughout, while protecting the safety of all personnel, Dujarric told reporters in New York.

Restraint urged as the mission departs

The Secretary-General is counting on the full cooperation of the parties to complete the process as soon as possible, the spokesperson added. He repeated the UN chief's message that MINURSO's departure “does not abrogate” the right of the people of Western Sahara to self-determination, and his call on all concerned to exercise “maximum restraint”.

What the phased closure signals

The decision not to renew the mandate places the mission's exit in the hands of a liquidation team rather than a political process, and the UN's language is carefully calibrated to separate the operational withdrawal from the political question. The emphasis on self-determination and restraint reflects concern that the departure could be read as a change in the legal or political status of the territory. The phased handover of 13 facilities and team sites, alongside the repatriation of military observers and departure of civilian personnel, will be watched as a test of whether the drawdown remains orderly.

Three crises, one common thread

Across Taiz, Afghanistan and Western Sahara, the common thread is the withdrawal of institutional presence — whether through siege, funding or mandate expiry — and the human cost that follows when the substitute is distance, expense or nothing at all. In Taiz, the blockade is physical. In Afghanistan, it is financial. In Western Sahara, it is political and administrative. Each case tests the same proposition: that humanitarian access and health capacity depend on systems that must be actively sustained, not merely declared.
