Oxfam aid workers warn that a humanitarian crisis in Taiz, Yemen, could become unmanageable as water, fuel and fresh food run short.

Iran-allied Houthi forces have largely surrounded the city, home to more than 900,000 people, and cut off most supply routes. Heavy fighting around its old airport this week has damaged a densely populated residential area. The World Food Programme said the city's wheat flour reserves were nearly exhausted by mid-October.

The United Nations has called for aid workers to be allowed into Taiz. Oxfam has urged the UK to send more humanitarian aid to Yemen, where donors have committed just 23% of the funding sought for this year's UN relief programme.

Fighting intensified after forces loyal to Yemen's internationally recognised government and the Saudi-led coalition struck the Houthi-held airport in Sana'a in July, breaking a 2022 ceasefire that had largely halted the conflict.
