The UN and partners estimate that at least US$6.6 billion is required to address the humanitarian needs of 3.3 million people in Gaza and the West Bank, including East Jerusalem (any reference to the West Bank in this document includes East Jerusalem). To be able to implement the full scale of what is urgently needed, Israel must take immediate and effective measures to ensure the essential needs of civilians are met. This includes lifting all impediments to aid and fully facilitating humanitarian operations, including the distribution of essential goods to Palestinians in need. Humanitarian actors anticipate being limited in what they can achieve in 2025 due to severe restrictions on humanitarian actors and ever greater challenges to their ability to operate, including intensified and coordinated anti-UN rhetoric strategically aimed at delegitimizing humanitarian efforts. Full compliance with international humanitarian law would allow humanitarians to use the full US$6.6 billion required and meet the essential needs of civilians.
Assuming humanitarian actors will continue to face a constrained operating environment, the 2025 OPT Flash Appeal calls for US$4 billion of this amount for UN Agencies, INGO, and NGO partners to address some of the most urgent and critical needs of three million of the 3.3 million people identified as requiring assistance.
The Appeal will target the entire population of Gaza, estimated at 2.1 million people, and 900,000 people in the West Bank. For the West Bank, this reflects an incremental increase compared to 2024 resulting from rising needs linked to the deteriorating situation.
The speed and scale of the killing and destruction in the Gaza Strip (Gaza) are unlike anything seen in recent history. At the same time, violence in the West Bank has sharply escalated. The conflict is now a regional one, and there is a considerable risk that the situation in the West Bank will also worsen. Similarly, the magnitude of this response and operational constraints are beyond what has been seen before in OPT.
Without sustained solutions to end the violence, humanitarian needs will continue to rise. Beyond peace, genuine efforts to enable humanitarian assistance will require critical changes in the operating environment, including:
The main response priority is to scale the humanitarian response to address the current level of needs across OPT. This will be done by:
Protection serves as the foundation for the overall response which will be inclusive and genderresponsive with a specific focus on gender-based violence (GBV) and on children.
