The United States, Egypt and Qatar have spent the past year trying to mediate an end to the 15-month war and secure the release of dozens of hostages.

Hamas is expected to release 33 hostages during the first phase of an emerging ceasefire agreement being finalized by negotiators in Doha, two Israeli officials said.

The negotiations, mediated by Qatar, Egypt and the United States, appear to be making progress after months of failed attempts to achieve a breakthrough.
