President Joe Biden has been generally supportive of Israel's right to defend itself following a terror attack last month that claimed the lives of 1,400 people.

Those sentiments aren't shared by everyone in Biden's administration, however, as some White House staff appear to be on the verge of mutiny.

Hundreds demand ceasefire

According to Fox News, some four hundred individuals have signed a letter condemning the president's stance regarding Israel.

Despite remaining anonymous, the signatories are said to hail from forty different federal departments and agencies, including the State Department, the Justice Department, and the National Security Council.

"We call on President Biden to urgently demand a cease-fire; and to call for de-escalation of the current conflict by securing the immediate release of the Israeli hostages and arbitrarily detained Palestinians," Fox News quoted the letter as saying.

It went on to call for "the restoration of water, fuel, electricity and other basic services; and the passage of adequate humanitarian aid to the Gaza Strip."

Israeli prime minister says military action aimed at free hostages

Israel has resisted calls for a ceasefire, with Israeli Prime Minister Benjamin Netanyahu recently arguing that continued military efforts are necessary to recover the hundreds of hostages that were taken by Hamas.

"I can say that we weren't close at all until we started the ground operation," the Israeli prime minister said when asked by host Kristen Welker about efforts to free the hostages.

"In fact, we heard that there is an impending deal of this kind or that kind, and then we learned that it was all hokum. It was nothing. But the minute we started the ground operation, things began to change," he stressed.

Fox News noted that for its part, the Biden administration has avoided calling a ceasefire in favor of humanitarian pauses, something Israel has agreed to.

Barack Obama: "Nobody's hands are clear"

Administration staff members are not alone in breaking with Biden over Israel as former President Barack Obama has also adopted a different stance than his one-time vice president.

"You have to admit that nobody's hands are clean, that all of us are complicit to some degree," Obama said during an interview earlier this month with the liberal podcast "Pod Save America."

"What Hamas did was horrific and there's no justification for it. And what is also true is that the occupation and what's happening to Palestinians is unbearable," he insisted.
