Hamas must disarm and recognise Israel under a Palestinian unity deal announced on Thursday with its rival Fatah aimed at ending their decade-long split, an Israeli government official said.
The two sides remain sharply at odds, however, over the future of Hamas's 25,000-strong armed wing, which the terror group says is nonnegotiable.

Hamas's agreement to transfer administrative powers in Gaza to a Fatah-backed government marked a major reversal, prompted partly by its fears of financial and political isolation after its main patron and donor, Qatar, plunged in June into a major diplomatic dispute with key allies like Saudi Arabia.

Al-Ahmed highly appreciated the Egyptian role and keenness to achieve Palestinian reconciliation, stressing that Egypt is the sponsor of the Arab national security, including the Palestinian security.
In return, Cairo pressed Hamas to move forward on reconciliation with Fatah.
Over the past decade, each side deepened control over its territory, making it increasingly hard to forge compromises and repeated attempts at reconciliation failed.
Yahya Sinwar, Hamas's acting chief in Gaza, for his part, congratulated Abbas on the watershed agreement. It also added that the Presidential Guard of President Mahmoud Abbas will operate the border, under a reconciliation deal.
