DOHA: Aid groups and other UN agencies have urged donors to keep supporting UNRWA, with the head of the World Health Organization warning on Wednesday that defunding would have “catastrophic consequences” for the people of Gaza. The United Nations Palestinian refugee agency said on Thursday that it will most likely be forced to shut down its operations in the Middle East, including in Gaza, by the end of the month if funding does not resume. A string of countries including the US, Germany and Britain have paused their funding to the aid agency in the wake of allegations that some UNRWA staff were involved in Hamas’ Oct. 7 attacks in southern Israel. “The agency remains the largest aid organization in one of the most severe and complex humanitarian crises in the world,” UNRWA Commissioner-General Philippe Lazzarini said in a statement. “If the funding remains suspended, we will most likely be forced to shut down our operations by end of February not only in Gaza but also across the region.” The Israeli offensive launched in the wake of the attacks, in which some 1,200 people were killed and 253 taken hostage, has displaced most of Gaza’s population, left many homes and civilian infrastructure in ruins, and caused acute shortages of food, water and medicine. Israeli authorities have long called for the agency to be disman- tled, arguing that its mission is obsolete and fosters anti-Israeli sentiment, something UNRWA has vigorously denied. On Wednesday, Israeli Prime Minister Benjamin Netanyahu reiterated his call to terminate UNRWA’s mandate and to replace it with other UN or non-UN aid agencies.
