Hostilities re-intensified in southwestern Yemen at the beginning of September, leading to one of the most rapid displacement surges in the conflict's twelve-year history. Between August 1 and September 20, approximately 131,274 individuals were displaced, with 2,892 new displacements recorded on September 21 alone.

The escalation of conflict is exacerbating acute health threats and increasing the risk of gender-based violence. Humanitarian funding remains well below requirements, with only 64% of the necessary funds secured.

The renewed fighting has resulted in a substantial increase in internally displaced persons, with 21,272 individuals currently displaced. This displacement surge places additional strain on already vulnerable populations.

The specific impact of the renewed hostilities on food security, water, sanitation, and hygiene services is not yet covered in recent reporting.
