Israel will send a delegation to Qatar on Sunday for talks on a possible Gaza hostage and ceasefire deal, although Prime Minister Benjamin Netanyahu's office said the changes requested by Hamas to a ceasefire proposal were unacceptable.

Israel rejected Hamas' proposed changes to the latest Gaza hostage and ceasefire deal, but will send negotiators to Qatar on Sunday to try to close remaining gaps, Prime Minister Benjamin Netanyahu's office said Saturday.

The deal comes more than 20 months into the conflict -- and more than three months after a previous deal ended.
