At least 76,000 people have been displaced across Yemen since July, with that number quadrupling in a single week as Houthi forces push against Yemen's internationally recognised government in intensifying fighting over the Red Sea coast. The International Organization for Migration (IOM) has warned that the displacement crisis is "deteriorating rapidly" and is calling for an urgent increase in international humanitarian support.

The hardest-hit area is the governorate of Taiz, a densely populated province in southwestern Yemen, where around 8,300 households — nearly 50,000 people — have fled their districts. Families, many moving under cover of darkness with only the clothes on their backs, are heading largely southward. The port city of Aden, which serves as the seat of the internationally recognised government, remains a relatively safe destination for now, though IOM's Yemen representative, Abdusattor Esoev, cautioned that arrivals there are expected to grow in coming days. A further spillover into the neighbouring governorate of Lahej is also anticipated if fighting continues.

At the heart of the military confrontation is the Bab al-Mandeb strait, a narrow chokepoint between Yemen and Djibouti that connects the Red Sea to the Gulf of Aden — one of the world's most strategically important shipping lanes. Houthi forces, who control much of northern Yemen including the capital Sanaa, and the southern-based government forces have been trading strikes in and around this critical corridor. A separate incident in the region saw an Iranian commercial vessel attacked near Qeshm Island in the Persian Gulf, killing one person and wounding three others, with Iranian officials attributing blame to the United States.

The latest surge of displacement adds a new layer to what is already one of the world's most protracted humanitarian emergencies. Yemen has been mired in civil war for over twelve years. It currently holds the grim distinction of having the largest internally displaced population in the world, with 4.5 million people uprooted before this latest escalation. Many of those now fleeing have already been displaced multiple times, and the IOM says they arrive exhausted and without resources.

The humanitarian response is severely underfunded: the IOM's 2026 response plan has received less than 20 percent of the financing it requires. Aid teams are distributing emergency shelter materials and hygiene kits, but Esoev acknowledged that "needs far exceed what we can provide." The IOM is urging all parties to the conflict to exercise restraint, guarantee safe passage for civilians, and allow humanitarian aid to reach those in need — appeals that have so far gone largely unheeded in one of the world's longest-running conflicts.
