The Biden administration last week put a hold on a shipment of U.S.-made ammunition to Israel, two Israeli officials told Axios.

Why it matters: It is the first time since the Oct. 7 attack that the U.S. has stopped a weapons shipment intended for the Israeli military.

• The incident raised serious concerns inside the Israeli government and sent officials scrambling to understand why the shipment was held, Israeli officials said.
• President Biden is facing sharp criticism among Americans who oppose his support of Israel. The administration in February asked Israel to provide assurances that U.S.-made weapons were being used by Israel Defense Forces in Gaza in accordance with international law. Israel provided a signed letter of assurances in March.
