Two far-right ministers had voiced opposition to the deal, with one threatening to quit the cabinet, but US Secretary of State Antony Blinken said he believed the ceasefire would go ahead on schedule.
“I am confident and I fully expect that the implementation will begin, as we said, on Sunday,” he said.
Gaza’s civil defense agency said Israel bombed several areas in the territory since the accord was announced on Wednesday, killing more than 100 people and injuring hundreds.
Hamas’ armed wing, the Azzedine al-Qassam Brigades, warned that Israeli attacks were putting the lives of hostages freed under the deal at risk, and could turn their “freedom… into a tragedy”.
According to an AFP tally of Israeli official figures, the war began with an attack on Israel on 7 October 2023, resulting in the deaths of 1,210 people, mostly civilians.
Of the 251 taken hostage, 94 are still in Gaza, of whom 34 have been killed according to the Israeli military.
Israel’s retaliatory campaign has destroyed much of Gaza, killing 46,788 people, most of them civilians, according to figures from the Hamas-run territory’s health ministry, which the United Nations considers credible.
