United Nations agencies have warned that Yemen’s Taiz City is facing a rapidly deteriorating humanitarian emergency after 20 days of isolation amid attacks between Houthi forces and government troops, with disrupted supply routes threatening access to food, clean water and essential assistance for hundreds of thousands of people.
The escalating violence along Yemen’s west coast has prevented humanitarian organisations from reaching vulnerable communities, while shortages of fuel and essential supplies are worsening already difficult living conditions.
More than 800,000 people in Taiz have been cut off from assistance, including 600,000 people who depend on humanitarian support and 200,000 women and children, according to the UN World Food Programme (WFP).
The latest escalation between Houthi forces and the Aden-based government began in early September 2026, ending the relative calm established under a 2022 truce.
Jens Laerke, Spokesperson for the UN Office for the Coordination of Humanitarian Affairs (OCHA), stated that, “it’s 20 days and counting since Taiz has been cut off. We are seeing increasingly that the fighting makes it impossible for us to get in and impossible for people to get out.”
“Access roads have been cut off and that means that very little fuel, food or other supplies have reached the city since.”

Azfar Deen, WFP Regional Communications Officer for Eastern and Southern Africa, added that the agency is “desperately trying to regain access to Taiz and we continue to support the broader operations across Yemen.”
Water Shortages and Rising Costs Deepen Humanitarian Crisis
The blockade of Taiz has intensified concerns about access to clean water, with residents facing dwindling supplies and sharply rising costs as fuel shortages disrupt water production and distribution.
OCHA indicated that most residents rely on water delivered by trucks, but the closure of access roads and scarcity of diesel have significantly reduced the supply available to households.
“With the roads closed and the diesel to run the trucks very scarce, water production in the city has fallen by about half. And the cost of the truck water has roughly tripled. You can imagine what that does to these people who are trapped there.”

The disruption threatens to make water increasingly unaffordable for families already struggling to secure food and other basic necessities. With supply routes blocked, the limited fuel reaching the city has further constrained the movement of essential goods and the delivery of humanitarian assistance.
The UN Children’s Fund (UNICEF) has also raised concerns about worsening hunger and malnutrition across Yemen, particularly among children in Taiz.
The agency has screened more than 168,000 children in Taiz this year, identifying over 52,000 with acute malnutrition, including more than 11,500 suffering from severe acute malnutrition.
To support treatment, UNICEF has pre-positioned nearly 8,000 cartons of ready-to-use therapeutic food across Taiz governorate, providing enough supplies to sustain services for approximately three months.
However, the agency warned that the availability of supplies does not necessarily guarantee that vulnerable children will receive treatment while fighting continues to restrict movement.
According to UNICEF spokesperson Ricardo Pires, “even when stocks are available, access constraints and disruptions to supply routes can make it more difficult for partners to transport supplies and for families to safely reach treatment.”
Displacement Rises as Families Flee Escalating Violence
The worsening security situation has also forced thousands of families to flee their homes, placing additional pressure on communities and displacement sites already struggling to accommodate people escaping the conflict.
The International Organization for Migration (IOM) recorded approximately 258,679 displaced individuals between June 7 and October 19, 2026, with the majority in Taiz and Lahj governorates.
Many families have been displaced repeatedly as violence spreads, seeking refuge in host communities and displacement sites where resources and essential services are already stretched.
The crisis has also prompted some Yemenis to seek safety outside the country. Recent figures indicate that a reported 3,836 Yemeni nationals have arrived in Djibouti, fleeing the deteriorating security situation.
Reports also indicate that at least 1,574 people have been killed and 6,939 others injured in the Yemen conflict since August.
Aid organisations encounter increasing difficulties in providing food, water, medical supplies, and nutrition support to vulnerable communities since Taiz is still blocked off from normal humanitarian access.
