Gaza ceasefire in peril as Israel and Hamas hit impasse

The testing second stage of Gaza's ceasefire was always in doubt; now it seems to be dead at the moment it was meant to start.

Concern is mounting that war will return to this ravaged territory, deepening the profound suffering of Palestinians and threatening the lives of the remaining hostages held by Hamas.

Israel, backed by the United States, says there is a new deal now, after the agreement's first phase ended on Saturday. And it has halted all humanitarian aid to Gaza until Hamas accepts this new version too.
