Fighting has severed all road access into Taiz, Yemen's third-largest city, triggering an urgent appeal from Tom Fletcher, the UN Emergency Relief Coordinator, for immediate humanitarian access. The UN Office for the Coordination of Humanitarian Affairs (OCHA) confirmed on Monday, 3 November 2025 that nearly a quarter of a million people have been cut off from essential health care, including more than 186,000 children under the age of five and 23,000 pregnant women.

Scale of the Humanitarian Crisis

OCHA warned that 12 hospitals are at risk of closing or have already been forced to reduce services due to critical shortages of fuel and medical supplies. In a single week, more than 1,400 cases of acute diarrhoea and suspected cholera were recorded — a stark indicator of a public health system under severe strain. 'Health services in the city are failing under the strain of lack of supplies and access to the city,' OCHA said in its statement.

The disease burden compounds an already dire displacement crisis. Since early August 2025, when the latest round of fighting erupted, nearly 300,000 people have been forced from their homes in Taiz and surrounding areas. This is in addition to the 5.2 million people who were already displaced across Yemen — out of a total population of 35 million — before the current escalation began.

UN Relief Chief Engages Yemeni Authorities

Tom Fletcher held direct talks with Yemeni Foreign Minister Afrah Abdulaziz Saleh Alzouba, discussing the displacement of civilians in Taiz, the rapidly rising humanitarian needs, and the critical requirement for unimpeded access so aid partners can resume deliveries, according to OCHA. The conversation reflects growing alarm at the UN that the Taiz crisis could deteriorate into a full-scale humanitarian emergency if access is not restored swiftly.

Humanitarian partners have, wherever access permits, already provided more than 254,000 displaced people with food, hygiene supplies, and emergency cash assistance. OCHA said it is simultaneously coordinating with health partners on a 90-day emergency plan to keep life-saving services operational, restore disrupted care, and strengthen disease surveillance across affected areas.

Civilian Casualties and Child Toll

The UN Human Rights Office has verified 272 civilian casualties since the beginning of August 2025 — comprising 68 killed and 204 injured. Critically, children account for 40 per cent of all verified casualties, a proportion that rights monitors say underscores the indiscriminate nature of the violence.

The UN has reiterated its call on all parties to the conflict to protect civilians and civilian infrastructure, respect international humanitarian law, and allow safe, sustained, and unimpeded humanitarian access — including free passage into Taiz.

Context: Yemen's Prolonged Conflict

Yemen has been locked in a devastating civil war for over a decade, pitting the internationally recognised government against Houthi forces, with multiple ceasefires and peace processes stalling over the years. Taiz has historically been one of the most contested cities in the conflict. The latest flare-up since August 2025 represents a significant setback to fragile stabilisation efforts and has reversed gains made in easing humanitarian access in previous months.

What Happens Next

The 90-day emergency health plan is now the most immediate operational priority, but its success hinges entirely on road access being restored. Aid agencies are warning that without a breakthrough in access, the cholera risk alone could spiral into a citywide outbreak within weeks. All eyes are on diplomatic channels — and whether Fletcher's engagement with Yemeni authorities translates into verifiable, sustained access on the ground.
