President Biden told Israeli Prime Minister Benjamin Netanyahu in a phone call on Thursday that U.S. policy on the war in Gaza will be determined by whether Israel takes “a series of specific, concrete and measurable steps” to address deaths of civilians and aid workers in the territory, the White House said.

The phone call came after seven aid workers with World Central Kitchen were killed in Israeli strikes. Biden said the strikes and the humanitarian situation in Gaza were unacceptable and urged Netanyahu to conclude hostage talks so that an “immediate ceasefire” can be put in place and more aid distributed in the region.

“He made clear the need for Israel to announce and implement a series of specific, concrete, and measurable steps to address civilian harm, humanitarian suffering, and the safety of aid workers,” the White House said in a statement after the call.

“He made clear that U.S. policy with respect to Gaza will be determined by our assessment of Israel’s immediate action on these steps. He underscored that an immediate ceasefire is essential to stabilize and improve the humanitarian situation and protect innocent civilians, and he urged the prime minister to empower his negotiators to conclude a deal without delay to bring the hostages home,” the White House said.

John Kirby, a spokesperson for the National Security Council, told reporters that the White House hopes to see a dramatic increase in aid getting into Gaza and “a reduction in the violence against civilians and certainly aid workers.”

Kirby said the White House wanted to see “concrete, tangible steps” in “the coming hours and days” but declined comment on what the consequences would be if those actions fail to materialize.

“What we want to see are some real changes on the Israeli side. And if we don’t see changes from their side, there will have to be changes from our side,” Kirby told reporters.
