The Biden administration has put a hold on a shipment of U.S.-manufactured ammunition to Israel for the first time since the deadly Oct. 7 Hamas terror attack, according to a report.

Two Israeli officials told Axios that the weapons shipment was stopped last week, leaving officials within the Israeli government scrambling to understand why.

When asked about the report, a spokesperson for the White House National Security Council told Fox News Digital that it has supported Israel’s defense since the Oct. 7 attack.

‘The United States has surged billions of dollars in security assistance to Israel since the October 7 attacks, passed the largest ever supplemental appropriation for emergency assistance to Israel, led an unprecedented coalition to defend Israel against Iranian attacks, and will continue to do what is necessary to ensure Israel can defend itself from the threats it faces,’ the statement said.

Israeli Prime Minister Benjamin Netanyahu has vowed to carry out a military operation in Rafah, a city in southern Gaza where some 1.5 million Palestinians have taken shelter, and where Hamas maintains its last remaining stronghold.

The potential Rafah operation to root out Hamas terrorists comes despite warnings from President Biden and other Western officials that doing so would result in more civilian deaths and worsen an already dire humanitarian crisis.

The Biden administration has said there could be consequences for Israel should it move forward with the operation without a credible plan to safeguard civilians.

Biden has also faced criticism from Americans who are against his support of Israel, most recently seen in protests that have erupted across college campuses nationwide. 

The current war in Gaza began after the Oct. 7 Hamas attack on Israel, in which the terrorist organization killed 1,200 people, and took about 250 people hostage.
