Fifteen trucks carrying humanitarian aid have arrived into Gaza from Egypt, according to the Palestinian Red Crescent Society.

The trucks include food, water and medical supplies, the Palestinian Red Crescent said in a statement Sunday evening.

Earlier on Sunday, 17 trucks crossed the Egyptian-Gaza border, according to a source in Egypt’s security forces.

Under the agreement between Egypt and Israel, Egypt can send humanitarian aid into Gaza. Israel has demanded it inspect those shipments at a nearby Israeli checkpoint before they pass into Gaza.

The Israel Defense Forces struck two Hezbollah terrorist cells near the Israel-Lebanon border in Lebanese territory, the IDF announced on Sunday.

One cell, which the IDF said planned to launch anti-tank missiles, was adjacent to the area of Mattat, a small community in northern Israel. The other cell was located in Har Dov, in southeastern Lebanon, and also planned to launch rockets, according to the IDF.

Separately, Israeli Prime Minister Benjamin Netanyahu held a series of talks with Western leaders on Sunday, in which he discussed Israel’s determination to eliminate the military and governmental capabilities of Hamas, his office announced.

"Israel's victory over Hamas is the victory of the entire world," Netanyahu said in a statement.

Netanyahu spoke to French President Emmanuel Macron, Spanish Prime Minister Pedro Sanchez and Dutch Prime Minister Mark Rutte, his office said.

The Biden administration is asking Israel to delay the looming ground incursion into Gaza to allow time for the release of more hostages and for humanitarian aid to get to civilians in Gaza, an administration official told ABC News Sunday.

The administration continues to impress upon the Israelis their concerns and the full array of consequences for a speedy ground incursion.

Two American hostages, 59-year-old Judith Raanan, and her 17-year-old daughter, Natalie Raanan, were released by Hamas on Friday.

President Joe Biden received a briefing from his national security team Sunday morning on the Israel-Hamas conflict and the president later spoke to Israel Prime Minister Benjamin Netanyahu. The leaders discussed ongoing efforts to release all the remaining hostages and to provide a way out for U.S. citizens and others in Gaza, White House officials said.

The Israel Defense Forces said Sunday that 212 hostages remain in captivity in Gaza.
