Israel demands release of all Gaza hostages, casting doubt on ceasefire proposal.
Hostages' families and their supporters want the Israeli government to agree a deal to end the war and bring them all home.
Israel is demanding the release of all 50 hostages held in Gaza, an Israeli official has said, casting doubt on whether it will accept a new proposal for a 60-day ceasefire that Hamas agreed to on Monday.
The proposal, put forward by Qatar and Egypt, would see the release of around half the hostages and is "almost identical" to a US proposal Israel had previously accepted, according to Qatar.
Israel has not explicitly rejected it - but Israeli government spokesman David Mencer told the BBC that it is not interested in "partial deals".
"Things have changed now. The prime minister has laid out a plan for the future of Gaza," Mencer said.
Palestinian sources said the proposal would see 10 living and 18 dead hostages handed over while the sides negotiated a permanent ceasefire and the return of the other hostages.
Israel believes that only 20 of the 50 hostages are still alive after 22 months of war.
Later this week, the Israeli cabinet is expected to approve the military's plan to occupy Gaza City, where intensifying Israeli strikes have already prompted thousands of people to flee.
Israeli Prime Minister Benjamin Netanyahu announced Israel's intention to conquer all of Gaza - including the areas where most of its 2.1 million Palestinian residents have sought refuge - after indirect talks with Hamas on a ceasefire deal broke down last month.
