BEIRUT (AP) Hamas said Thursday that it was sending a delegation to Egypt for further cease-fire talks , in a new sign of progress in attempts by international mediators to hammer out an agreement between Israel and the militant group to end the war in Gaza .

After months of stop-and-start negotiations, the cease-fire efforts appear to have reached a critical stage , with Egyptian and American mediators reporting signs of compromise in recent days. But chances for the deal remain entangled with the key question of whether Israel will accept an end to the war without reaching its stated goal of destroying Hamas.

The stakes in the cease-fire negotiations were made clear in a new U.N. report that said if the Israel-Hamas war stops today, it will still take until 2040 to rebuild all the homes that have been destroyed by nearly seven months of Israeli bombardment and ground offensives in Gaza. It warned that the impact of the damage to the economy will set back development for generations and will only get worse with every month fighting continues.
