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.

U.S.-led ceasefire efforts in Gaza appeared to gain momentum Saturday after nearly 21 months of war as Prime Minister Benjamin Netanyahu's office said Israel on Sunday will send a negotiating team to talks in Qatar.

Hamas has demanded that the United Nations be allowed to resume aid distribution across more than 400 points in Gaza, a system used before the collapse of the last ceasefire in March. Israel, however, seeks to maintain control through the Gaza Humanitarian Foundation.
