Israel boycotted Gaza cease-fire talks in Cairo on Sunday after Hamas rejected its demand for a complete list naming hostages that are still alive, an Israeli newspaper reported.

A Hamas delegation arrived in Cairo for the talks, billed as a possible final hurdle before an agreement that would halt the fighting for six weeks. But by the evening there was no sign of the Israelis.

"There is no Israeli delegation in Cairo," Ynet, the online version of Israel's Yedioth Ahronoth newspaper, quoted unidentified Israeli officials as saying. "Hamas refuses to provide clear answers and therefore there is no reason to dispatch the Israeli delegation."
