The impact of Israel’s war in the Gaza Strip could erase “over 69 years of progress” in the enclave, the United Nations has warned in a new report, saying that measurement for indicators such as life expectancy, education, income and standard of living are projected to drop to a level estimated for 1955.

The UN Development Programme (UNDP) said that without “lifting economic restrictions, enabling recovery, and investing in development, the Palestinian economy may not be able to restore pre-war levels and advance forward by relying on humanitarian aid alone.”

“Projections in this new assessment confirm that amidst the immediate suffering and horrific loss of life, a serious development crisis is also unfolding – one that jeopardizes the future of Palestinians for generations to come,” said Achim Steiner, UNDP administrator.

The UN report comes as US Secretary of State Anthony Blinken visits the Middle East to “emphasize the need to chart a new path forward that enables Palestinians to rebuild their lives and realize their aspirations free from Hamas’s tyranny,” according to the State Department.

Israel launched a war on Hamas in Gaza on October 7 last year after the group attacked southern Israel, killing 1,200 people and taking more than 250 hostages. The Israeli offensive has killed more than 42,000 people in Gaza, according to the health ministry there, displaced most of its people and flattened large swathes of the enclave.

The UN report, which looks at estimates for the Palestinian territories as a whole, says that over 4 million people in them were affected by poverty in 2024, including 2.6 million newly impoverished people. This brings the poverty rate to 74.3% across the Palestinian territories, according to the report.

Palestinian Authority President Mahmoud Abbas has accused Israel of almost entirely destroying Gaza, saying it is “no longer fit for life.” This month, a UN inquiry accused Israel of carrying out a “concerted policy” of destroying Gaza’s health care system, adding that its policies “constitute the war crimes of willful killing and mistreatment and the crime against humanity of extermination.” The Israeli foreign ministry called the accusations “outrageous.”
