CAIRO (AP) — Egypt sent a high-level delegation to Israel on Friday with the hope of brokering a cease-fire agreement with Hamas in Gaza, two officials said. At the same time, it warned that a possible Israeli offensive focused on Gaza’s city of Rafah — on the border with Egypt — could have catastrophic consequences for regional stability.

Egypt’s top intelligence official, Abbas Kamel, is leading the delegation and plans to discuss with Israel a “new vision” for a prolonged cease-fire in Gaza, an Egyptian official said, speaking on condition of anonymity to discuss the mission freely.

As the war drags on and casualties mount, there has been growing international pressure for Hamas and Israel to reach an agreement on a cease fire.

Friday’s talks will focus at first on a limited exchange of hostages held by Hamas for Palestinian prisoners, and the return of a significant number of displaced Palestinians to their homes in northern Gaza “with minimum restrictions,” the Egyptian official said.
