Trump hints at 'action' if Hamas doesn't return hostage bodies

Secretary of State Marco Rubio weighed in on West Bank annexation last night as he departed for Israel, giving a seemingly coordinated message from the administration as they work to keep the fragile U.S.-brokered ceasefire intact.

"The President’s made clear that’s not something we’d be supportive of right now, and we think it’s potentially threatening to the peace deal. So, they’re a democracy, they’re going to have their votes, people are going to take these positions, but at this time it’s something that, especially, we think it might be counterproductive," Rubio said Wednesday night before heading to Israel.

President Donald Trump reiterated the same message in his TIME interview, saying it's a delicate balancing act to manage in keeping both sides motivated to prevent the collapse of the ceasefire.

“It won't happen. It won't happen. It won’t happen because I gave my word to the Arab countries," Trump said of West Bank annexation.

U.S. Vice President JD Vance criticized Israeli parliament's vote on the annexation of the West Bank in his remarks as he talked to press at the airport in Tel Aviv before leaving on Thursday.

"I personally take some insult to it," Vance said, talking about the Knesset vote on the matter.

“Israel is not going to annex the West Bank,” he added.

There are 500 tons of lifesaving aid, including medical equipment and hygiene supplies, for Gaza stuck at the border "due to ongoing bureaucratic delays by the Israeli authorities," according to the International Rescue Committee.

"IRC staff working inside Gaza have shared firsthand accounts of the immense suffering, loss, and resilience of communities. These testimonies reflect the daily reality faced by families across Gaza and underscore the urgent need for the continued reduction of violence and sustained humanitarian action," the IRC said in a statement Wednesday.

This comes one day after the World Food Programme said more border crossings need to be opened to allow in aid at the level needed to keep the famine from spreading.

"IRC staff on the ground report that thousands of displaced people and many who have returned to areas like Gaza City after the ceasefire are still struggling amid massive destruction. With homes reduced to rubble and basic services decimated, families are living without adequate shelter, clean drinking water, food, or sanitation," IRC said.

"Health facilities remain overwhelmed, leaving those in need of medical care unable to access lifesaving services, putting already vulnerable lives at even greater risk," the aid group warned.

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.
