Sources in the U.S. and Gulf states say that in recent days - amid the war with Iran - there have been positive developments in the "quiet" negotiations between Israel and Hamas regarding a hostage deal and ceasefire. Families of hostages reported being updated by official sources - Arab and others - that an Israeli delegation might soon depart for Doha, the capital of Qatar, with the aim of advancing talks and trying to achieve a breakthrough. Israeli security officials refused to comment.
