JERUSALEM (Reuters) - Israel sees no sign of a breakthrough in Egyptian-mediated talks on a truce with Hamas that would free some Gaza hostages, but is keeping its delegation of mid-level negotiators in Cairo for now, an Israeli official said on Wednesday.

William Burns, the director of the U.S. Central Intelligence Agency, was in Israel meeting Prime Minister Benjamin Netanyahu about a possible suspension of the Israeli operation in Gaza's Rafah in return for a hostage release, the official added.

The U.S. Embassy in Jerusalem had no comment on Burns' visit.
