TEL AVIV, Israel (AP) — The head of the U.N. food agency said Thursday that it was “very evident” during her visit to Gaza this week that there isn’t enough food in the Palestinian territory and that she spoke with Israeli Prime Minister Benjamin Netanyahu about the urgent need for more aid.

The world’s leading authority on food crises said last week the Gaza Strip’s largest city is gripped by famine, and that it was likely to spread across the territory without a ceasefire and an end to restrictions on humanitarian aid.

Cindy McCain, the World Food Program’s executive director, told The Associated Press that starvation was underway in Gaza.

“I personally met mothers and children who were starving in Gaza,” she said. “It is real and it is happening now,”

Netanyahu, she said, was “obviously very concerned that people aren’t getting enough food.” In the past, he has denied that there is famine in Gaza and said the claims about starvation are a propaganda campaign launched by Hamas.

“We agreed that we must immediately redouble our efforts to get more humanitarian aid in. Access and security for our convoys is critical,” McCain said.

The famine declaration has increased international pressure on Israel, which has been fighting Hamas since the militant group’s deadly Oct. 7, 2023, attack. Israel now says it plans to seize Gaza City and other Hamas strongholds, and there have been no public signs of progress on recent efforts for a ceasefire.

Israel rejects the declaration — issued by the authority on food crises known as the Integrated Food Security Phase Classification, or IPC — and on Wednesday asked for a formal retraction.

The Israeli military agency in charge of transferring aid to the territory, known as COGAT, said Thursday that more than 300 humanitarian aid trucks enter Gaza every day, most of them carrying food.

But aid groups say it’s not nearly enough after 22 months of fighting, the blockade of aid earlier this year and the collapse of food production in Gaza. McCain spent most of Tuesday on a tour of Gaza speaking to displaced families living in tents and facing hunger.
