Hamas has 72 hours to release the 20 living Israeli hostages it is still holding, in the next phase of Donald Trump’s peace agreement.
Trump said the hostages were due to “come back” on Monday.
Another 26 hostages are presumed dead and the fate of two is unknown.
Hamas has indicated that recovering the bodies of the dead may take longer than releasing those who are alive.
Under the agreement, the 72-hour deadline is triggered when the Israeli military withdraws from roughly half of Gaza.
Israel was given 24 hours to do so once the ceasefire was activated at 10am (UK time) yesterday. Israel and the US say the withdrawal has been completed.
Following the release of the living hostages, Israel will free 250 Palestinians serving long terms in its prisons and 1,700 detainees captured during the war.
