Introduction
This is the first update of the Flash Appeal for the Occupied Palestinian Territory (OPT), originally published on 12 October 2023. It identifies a financial requirement of approximately US$1.2 billion to meet critical needs for 2.7 million people across the OPT, the 2.2 million population of the Gaza Strip and 500,000 from the West Bank, including East Jerusalem from October – 31 December 2023. It outlines the minimum to prevent further loss of life considering the ongoing siege and bombardment of Gaza and the escalating situation in the West Bank.
