WASHINGTON — A lead organization monitoring food crises around the world withdrew a new report this week that warned of imminent famine in north Gaza under what it called Israel’s “near-total blockade,” after the U.S. asked for its retraction, U.S. officials told The Associated Press. The move follows public criticism of the report from the U.S. ambassador to Israel.

The rare public dispute drew accusations from prominent aid and human-rights figures that the work of the U.S.-funded Famine Early Warning System Network, meant to reflect the data-driven analysis of unbiased international experts, has been tainted by politics. A declaration of famine would be a great embarrassment for Israel, which has insisted that its 15-month war in Gaza is aimed against the Hamas militant group and not against its civilian population.

Jacob Lew, the U.S. ambassador to Israel, called the warning by the internationally recognized group inaccurate. Lew and the U.S. Agency for International Development, which funds the monitoring group, said the findings failed to properly account for rapidly changing circumstances in north Gaza.

Humanitarian and human rights officials expressed fear of U.S. political interference in the world’s monitoring system for famines. The U.S. Embassy in Israel and the State Department declined comment. FEWS officials did not respond to questions.

“We work day and night with the U.N. and our Israeli partners to meet humanitarian needs — which are great — and relying on inaccurate data is irresponsible,” Lew said Tuesday.

USAID confirmed to the AP that it had asked the famine-monitoring organization to withdraw its stepped-up warning issued in a report dated Monday. The report did not appear among the top updates on the group’s website Thursday, but the link to it remained active.

The dispute points in part to the difficulty of assessing the extent of starvation in largely isolated northern Gaza. Thousands in recent weeks have fled an intensified Israeli military crackdown that aid groups say has allowed delivery of only a dozen trucks of food and water since roughly October.

FEWS Net said in its withdrawn report that unless Israel changes its policy, it expects the number of people dying of starvation and related ailments in north Gaza to reach two to 15 a day between January and March.

The internationally recognized mortality threshold for famine is two or more deaths a day per 10,000 people.

FEWS was created by the U.S. development agency in the 1980s and is still funded by it. But it is intended to provide independent, neutral and data-driven assessments of hunger crises, including in war zones. Its findings help guide decisions on aid by the U.S. and other governments and agencies around the world.

A spokesman for Israel’s Foreign Ministry, Oren Marmorstein, welcomed the U.S. ambassador’s public challenge of the famine warning. “FEWS NET — Stop spreading these lies!” Marmorstein said on X.

In challenging the findings publicly, the U.S. ambassador “leveraged his political power to undermine the work of this expert agency,” said Scott Paul, a senior manager at the Oxfam America humanitarian nonprofit. Paul stressed that he was not weighing in on the accuracy of the data or methodology of the report.

“The whole point of creating FEWS is to have a group of experts make assessments about imminent famine that are untainted by political considerations,” said Kenneth Roth, former executive director of Human Rights Watch. “It sure looks like USAID is allowing political considerations — the Biden administration’s worry about funding Israel’s starvation strategy — to interfere.”

Israel says it has been operating in recent months against Hamas militants still active in northern Gaza. It says the vast majority of the area’s residents have fled and relocated to Gaza City, where most aid destined for the north is delivered. But some critics, including a former defense minister, have accused Israel of carrying out ethnic cleansing in Gaza’s far north, near the Israel border.

The U.S. and U.N. have said Gaza’s people as a whole need 350 to 500 trucks a day of food and other vital needs. But the U.N. and aid groups say Israel recently has again blocked almost all aid to that part of Gaza.

Israel says it places no restrictions on aid entering Gaza and hundreds of truckloads of goods are piled up at Gaza’s crossings. The U.N. and other aid groups say Israeli restrictions, ongoing combat, looting and insufficient security by Israeli troops make it impossible to deliver aid effectively.
