CAIRO — The cease-fire between Hamas and Israel will go into effect Sunday at 8:30 a.m. local time, mediator Qatar announced Saturday, as families of hostages held in Gaza braced for news of loved ones, Palestinians prepared to receive freed detainees, and humanitarian groups rushed to set up a surge of aid.

The UN secretary-general has reacted after Israel and Hamas agreed to have a ceasefire deal to halt the war in Gaza. The conflict had lasted several months.

Israel’s government voted in favour of the truce after the country’s security cabinet, chaired by Israeli prime minister Benjamin Netanyahu, agreed to the ceasefire and hostage deal earlier on Friday. The vote is believed to have been 24 in favour and eight against early on Saturday morning local time.
