Armed hostilities intensified in Taiz Governorate on September 3, leading to significant new population displacement. By September 5, the conflict had spread to Al Hodeidah Governorate on Yemen's West Coast. Ongoing shelling, insecurity, and rapidly shifting frontlines are reported.

Humanitarian operations face challenges due to movement restrictions and disruptions caused by the escalating conflict. Funding for humanitarian efforts remains well below requirements.

The escalation has resulted in 21,272 internally displaced persons. The affected populations require assistance across multiple sectors including food, nutrition, health, protection, shelter, and WASH.

Specific details on the number of people affected by movement restrictions and disruptions are not yet covered in recent reporting.
