Secretary of State Marco Rubio will travel to Israel this week, according to a senior State Department official.

Following the weekend violence in Gaza, several notable administration officials have made their way to Israel to shore up a fragile ceasefire agreement, including Vice President JD Vance, Special Envoy to the Middle East Steve Witkoff, and the president's son-in-law and businessman Jared Kushner.

Israel and Hamas are currently observing a U.S.-backed ceasefire. Questions remain over the deployment of an international security force in Gaza and who will govern the territory. U.S. officials have said they are brainstorming next steps.

Vice President JD Vance met with Israeli President Isaac Herzog during his visit to Israel, with the two saying they will continue to work together to insure the ceasefire agreement holds.

“I truly believe that the fact you're here is another brick in building the future for peace,” Herzog said before meeting with Vance.

“We all are grateful to President Donald Trump for his steadfast insistence on moving forward. We must move forward. We must offer hope for the region, for Israel, the Palestinians, our neighbors and for the future of our children. So we are grateful for your efforts,” Herzog added.

The International Court of Justice said Israel must allow the United Nations Relief and Works Agency for Palestine Refugees in the Near East, the U.N. aid agency in the Gaza Strip, to provide humanitarian assistance in the enclave, according to an extensive report on the court's official website on Wednesday.

The "occupying Power must allow and facilitate sufficient relief to ensure that population is adequately supplied. UNRWA cannot be replaced on short notice and without proper transition plan," the ICJ wrote in its opinion.

"Israel under obligation to agree to and facilitate relief schemes provided by United Nations and its entities, including UNRWA," the ICJ wrote.

Israel's Foreign Ministry "categorically" rejected the ICJ’s advisory opinion in a statement on its X account, describing it as "yet another political attempt to impose political measures against Israel."

Israel handed over bodies of 30 other Palestinian prisoners to the Gaza Strip on Wednesday as a part of the ceasefire agreement, according to the Nasser Medical Complex in Khan Younis.

Israel has now returned 165 Palestinian bodies, according to the enclave's government media office.

Not all of the Palestinian bodies returned by Israel could be identified by their families "due to the severe circumstances" surrounding their deaths, according to the Palestinian Civil Defense report on Wednesday.

A collective funeral ceremony was held for 54 unidentified Palestinians on Wednesday in Deir al-Balah, in central Gaza, as the Civil Defense reported.

Signs of abuse, beating, handcuffing, and blindfolding, and hanging on the neck were seen on the returned bodies, according to the Gaza Media Office and the Gaza Ministry of Health.

Rejecting reports of any torture signs, the Israeli military told ABC News in a statement on Wednesday that "the IDF did not tie any bodies prior to their release to the Strip," adding that they operate "strictly in accordance with international law."

Moureen Kaki, an American-Palestinian aid worker who examined living Palestinian prisoners and detainees upon their return to the Gaza Strip after the peace deal, told ABC News last week that all of 35 prisoners who talked to her had "experienced torture,” while in Israeli custody.

Some said they were beaten by Israeli soldiers “as early as two hours before their arrival into Gaza when they were waiting on the bus,” Kaki said. She added that three Palestinian men had open gunshot wounds from the last three weeks at the time.
