DEIR AL-BALAH, Gaza — The U.N. said Wednesday it was trying to get the desperately needed aid that has entered Gaza this week into the hands of Palestinians amid delays because of fears of looting and Israeli military restrictions. Israeli strikes pounded the territory, killing at least 86 people, according to Gaza’s Health Ministry.

Under international pressure, Israel has allowed dozens of aid trucks into Gaza after blocking all food, medicine, fuel and other material for nearly three months. But the supplies have been sitting on the Gaza side of the Kerem Shalom crossing with Israel.

U.N. spokesman Stephane Dujarric said the majority of supplies that had entered since Monday had been loaded onto U.N. trucks, but they could not take them out of the crossing area. He said the road the Israeli military had given them permission to use was too unsafe. Talks were underway for an alternative, he said.

A U.N. official later said some trucks had left the crossing area, heading for warehouses in Gaza, but there was no immediate confirmation they arrived. The official spoke on condition of anonymity, without authorization to talk to the press.

Food security experts have warned that Gaza risks falling into famine unless the blockade ends. Malnutrition and hunger have been mounting. Aid groups ran out of food to distribute weeks ago, and most of the population of around 2.3 million relies on communal kitchens whose supplies are nearly depleted.

Israeli strikes pounded the territory, killing at least 82 people, according to Gaza’s Health Ministry.

Israeli troops also fired warning shots as a group of international diplomats was visiting Jenin in the Israeli-occupied West Bank, the Israeli military said. It said their visit had been approved, but the delegation “deviated from the approved route.”

At the time, the delegation of about 20 regional, European and Western diplomats was near the entrance of the Jenin refugee camp being briefed by Palestinian Authority officials about the humanitarian situation, said an aid worker who was present.

No one was injured, she added, speaking on condition of anonymity. The military said it apologized and will contact the countries involved in the visit.

Israeli troops have raided Jenin dozens of times as part of a crackdown across the West Bank against militants since Hamas’ Oct. 7, 2023, attack on Israel that sparked the war in Gaza.

The fighting displaced tens of thousands of Palestinians, one of the largest West Bank displacements in years.

Israeli strikes continued across Gaza. In the southern city of Khan Younis, where Israel recently ordered new evacuations pending an expanded offensive, 24 people were killed, 14 from the same family. A newborn was killed in central Gaza.

Israeli troops also have surrounded two of northern Gaza’s last functioning hospitals, preventing anyone from leaving or entering the facilities, hospital staff and aid groups said this week.

Aid groups say the small amount of aid that Israel has allowed is far short of what is needed. About 600 trucks entered daily under the latest ceasefire.

The delays in distributing even that amount pointed to the turmoil in Gaza and increased regulations from the Israeli military.

COGAT, the Israeli defense body overseeing aid for Gaza, said trucks were entering Wednesday, but it was unclear if that aid would continue deeper into Gaza for distribution.

After supplies enter at Kerem Shalom, aid workers are required to unload them and reload them onto their own trucks for distribution.

A U.N. official and a humanitarian worker also said the Israeli military had designated an insecure route known to have looters for deliveries. The military also set a short window for trucks to come to Kerem Shalom and rejected a number of truck drivers, forcing last-minute replacements, they said. Both spoke on condition of anonymity.
