On 17 July, UNRWA launched a Flash Appeal for US$60 million to respond to the immediate needs of those affected by the ongoing emergency in the Gaza Strip. However, the dramatic escalation of the Israeli ground offensive in recent days has resulted in a massive increase in displaced persons with many seeking safety in UNRWA Designated Emergency Shelters (DES), and in significant further damage to homes and other civilian infrastructure. As of 21 July, the number of people taking refuge at the DES’s has exceeded 100,000 people. This number continues to increase by the hour. In response to escalating humanitarian needs, UNRWA has revised its emergency response and expanded it to meet the greater scope of immediate and medium-term needs resulting from the intensified population displacement and infrastructure destruction. UNRWA has thus revisited the requirements presented in the Flash Appeal, and urgently seeks US$ 55 million in addition to the original $60 million.
