Hospitals and health officials have been preparing isolated areas where the hostages can begin recuperating, and there are concerns that the returning captives may be malnourished.

Israel’s cabinet approved an agreement on a cease-fire in the Gaza Strip that would free Israeli hostages, ending two days of debate that had underscored the pact’s fragility. The full cabinet endorsed the deal hours after the security cabinet had approved it.

Under the deal, bitterly opposed by some cabinet hardliners, a six-week ceasefire is due to take effect on Sunday, with the first of a series of hostage-for-prisoner exchanges that could open the way to ending the 15-month war in Gaza.
