A city of Taiz's size losing both its supply lines and its basic sanitation is a public health emergency in the making, and one that tends to compound quickly once water and refuse systems fail together.
Nearly 310,000 people in Yemen have been forced from their homes since the beginning of August because of fighting, according to the UN Office for the Coordination of Humanitarian Affairs. The figure, reported by the Russian state news agency TASS, points to a displacement wave of a scale that aid agencies have not recorded in Yemen for some years. OCHA said shelter remains a pressing need: around 37,000 families are waiting for shelter assistance, while 32,000 require basic household items.
The agency's response has been modest against that demand. Since August, 28 temporary accommodation sites have opened or resumed operations, sheltering more than 20,000 people. That leaves the great majority of the newly displaced outside organised sites, reliant on host communities, rented rooms or improvised arrangements. The numbers suggest a response that is scaling up but not yet matching the pace of the fighting.
The condition of Taiz is the clearest illustration of how the conflict is transmitted to civilians. OCHA says the city is running out of essential goods, with prices having risen as much as fivefold. Waste collection has stopped because trucks cannot reach dumping sites, and rubbish is piling up across the city, raising the risk of disease. A city of Taiz's size losing both its supply lines and its basic sanitation is a public health emergency in the making, and one that tends to compound quickly once water and refuse systems fail together.
The military trajectory explains the pressure. Armed conflict between the Houthis and government forces backed by Saudi Arabia has continued since August 2014. In July 2026, the rebels announced a naval blockade of the kingdom and subsequently attacked several Saudi-owned oil tankers. In early August, the Ansar Allah movement launched an offensive in southwestern Yemen; on 10-11 September it took control of the port city of Mokha and areas near the Bab el-Mandeb Strait. On 4 October, Yemeni government forces announced a large-scale military operation to retake rebel-held territory.
Control of Mokha and the ground near Bab el-Mandeb matters beyond Yemen. The strait is one of the world's principal maritime chokepoints, and rebel presence along its shores, combined with the declared blockade of Saudi Arabia and attacks on tankers, raises the cost and risk of shipping through the corridor. The displacement figures are the human accounting of that strategic contest, and they are likely to keep rising while the front lines move.
The UN has called on the parties to the conflict to protect civilians and to ensure safe, sustained and unimpeded humanitarian access to those affected. What is not yet known is how many of the displaced have crossed into neighbouring governorates or abroad, how much of the Taiz price surge reflects blockade rather than market disruption, and whether the government's October operation has altered access routes for aid convoys. OCHA's figures are a snapshot, and the next one will be the test of whether the response is catching up.
