There are also remaining differences between Israel and Hamas over the proposed swap of hostages held in Gaza for Palestinians prisoners held by Israel.

Netanyahu's office said Hamas had "reneged on parts of the agreement reached with the mediators and Israel in an effort to extort last-minute concessions."

The first phase of the deal reached between Hamas and Israel on Wednesday includes a pause in the war and the release of Israeli hostages held in Gaza and of Palestinian prisoners held in Israeli custody.
