The cease-fire between Hamas and Israel will go into effect 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.

Israeli Prime Minister Benjamin Netanyahu accused Hamas of backing out of a cease-fire deal to release hostages and end the war in Gaza, which has raged for more than a year.

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.
