The Israeli security cabinet is set to meet Tuesday morning to review a ceasefire proposal put forward by Egypt.
Israeli officials say the proposal is being taken very seriously. But Hamas may not be willing to negotiate.
A Hamas spokesman describes Egypt's proposal for a cease-fire as a joke: "It's an initiative for the media. It's not a political initiative."
U.S. officials, meanwhile, tell CNN Secretary of State John Kerry is preparing a possible trip to the Middle East to lay the groundwork for a ceasefire agreement.
