Israel frustrated U.S. paused weapons shipment over Rafah assault concerns,

The United States halted a large shipment of offensive weapons to Israel last week in a sign of its growing concern over a possible military offensive on Rafah, senior administration officials told NBC News.

The decision comes as President Joe Biden pushes for Israel and Hamas to compromise and reach a cease-fire deal that would head off a large-scale assault on the city in southern Gaza, where more than a million Palestinians are sheltering in dire conditions.

The Israeli military said it had reopened a key border crossing Wednesday following pressure from Washington, and a day after its ground forces seized control of the Gaza side of another crossing — a move that fueled fears for aid supplies coming into the enclave, but which U.S. officials said was a limited operation and not the full-scale assault Biden has warned against.

The Israeli military appeared to play down the dispute, with a spokesman saying Wednesday that the two allies resolve any disagreements “behind closed doors.”

But an Israeli official told NBC News there is deep frustration in the Israeli government over the decision. The official added that tensions had already been running high after Israel felt the U.S. allowed it to be blindsided by Hamas’ announcement earlier this week that it was accepting a version of a cease-fire proposal.

The White House halted the shipment of weaponry last week because of concern that it would be used in Rafah, a senior administration official said Tuesday night. The shipment included 1,800 2,000-pound bombs and 1,700 500-pound bombs, the official said.

The Biden administration had been “especially focused” on ending Israel’s use of 2,000-pound bombs in its offensive in Gaza, the official said, given the impact they have on dense urban areas.

Israel already has a large arsenal, making the halt unlikely to stop an offensive.  

The U.S. began reviewing future transfers of military assistance to Israel in April, as the government appeared to move closer to a Rafah operation despite the urging of Biden, other world leaders and humanitarian officials, the official said.

No final decision had been made on whether to proceed with the weapons delivery at a later date, the official said, adding that the State Department is separately considering whether to approve future weapons transfers, including Joint Direct Attack Munition kits, which place precision guidance systems onto bombs.

While the U.S. officials stressed that the pause does not indicate a larger shift in policy about providing weapons to Israel, it is a rare step that hints at the growing friction between the U.S. and its ally over the war.

CIA Director William Burns met with Israeli Prime Minister Benjamin Netanyahu during a trip to the country on Wednesday to consult with officials there on the latest round of cease-fire talks in Cairo, an Israeli official said.

Hamas on Monday said it had accepted the terms of a proposal brokered by Egypt and Qatar, but Israel said it was “far from” meeting its demands. Negotiators have been trying to resolve disagreements over phasing, among other differences over a truce deal that would secure the release of hostages, according to another senior administration official.

“It’s positive that they’re still meeting, but it’s too soon to be optimistic,” the official said. “We need them to close their differences, but the differences are minor.”

The decision to pause last week’s arms delivery, which was first reported by Axios, came to light as the Biden administration appeared set to miss a Wednesday deadline to submit a highly-anticipated report to Congress on whether Israel is using U.S. weapons in accordance with international law.

Multiple administration officials told NBC News the Biden administration would miss the deadline, with State Department spokesperson Matt Miller confirming to reporters Tuesday afternoon that a delay was possible.

“We are trying very hard to meet that deadline,” he said. “It’s possible it slips just a little bit but we’re still at this point trying to get it done by tomorrow.”

The report is mandated under a National Security Memo signed by Biden in February which requires the secretary of state or the defense secretary to assess whether recipients of U.S….
