Israel and Hamas have announced a ceasefire in Gaza lasting at least four days, allowing for humanitarian aid and the release of hostages.

However, hopes for a Thursday release were dashed, with both Israel's national security adviser and the U.S. confirming that the release won't happen before Friday.

While the start time is yet to be officially announced, Qatar's foreign ministry spokesperson mentioned that an announcement could come in the next few hours.

Qatar, mediating in the negotiations, reported ongoing progress, stating that the negotiations on the release of hostages are advancing. Israel's National Security Adviser emphasized that the release would adhere to the original agreement, not occurring before Friday.

White House spokesperson Adrienne Watson mentioned that logistical details for the release are being finalized, expressing hope for implementation starting on Friday morning. Despite the ceasefire agreement, reports indicate continued fighting, with Israeli strikes in Gaza and rocket warnings near the Israeli border.

The delay is attributed to the agreement not being signed by Hamas and Qatar, but optimism remains that it will be carried out once signed.

Since the Oct. 7 Hamas attack on southern Israel, five hostages have been recovered alive, while Israel reports civilian casualties and hostages of different nationalities taken. The truce aims to release at least 50 hostages in exchange for 150 Palestinians imprisoned in Israel.

The release is planned over four days, with the possibility of extending the truce as long as 10 hostages are freed daily. The deal also involves the entry of humanitarian supplies into Gaza and specific measures regarding air sorties.

The truce, mediated by Qatar, is seen globally as a potential relief for civilians in Gaza, described as the "most dangerous place in the world to be a child" by UNICEF, with over 5,300 Palestinian children reportedly killed since Oct. 7.
