CAIRO (AP) Hamas said Thursday that its delegation has left Cairo and that talks on a Gaza cease-fire and hostage release will resume next week, making it extremely unlikely that mediators will broker a deal before the Muslim holy month of Ramadan.

Egyptian officials had earlier said the negotiations reached an impasse over Hamas demand for a phased process culminating in an end to the war. But they did not rule out a deal before Ramadan, which is expected to begin on Sunday and has emerged as an informal deadline.

Hamas spokesman Jihad Taha said Israel refuses to commit to and give guarantees regarding the cease-fire, the return of the displaced, and withdrawal from the areas of its incursion. But he said the talks were still ongoing and would resume next week. There was no immediate comment from Israel.

The U.S., Egypt and Qatar have been trying for weeks to broker an agreement on a six-week cease-fire and the release of 40 hostages held in Gaza in exchange for Palestinians imprisoned in Israel.
