As Israel and Hamas edge closer to a possible ceasefire-hostage agreement, a small number of families whose loved ones remain captive in Gaza are saying “No” to a deal.

The first phase, spanning a 42-day ceasefire, would see the exchange of 33 Israeli hostages in Gaza for Palestinians held in Israeli prisons, U.S. officials said.

U.S., Arab and Israeli officials all tell CBS News that Israel and Hamas have agreed in principle to a ceasefire and hostage-release deal with final details being hammered out by negotiators in Qatar.
