‘Until the Last One’

One of the bodies that Hamas returned to Israel this week was not one of the remaining hostages being held in Gaza over the last two years, the Israeli military said on Wednesday. It is still unclear whom the wrongly identified person is, but such a mix-up could threaten the barely 5-day-old cease-fire deal and reignite conflict in the territory.

As part of the U.S.-brokered cease-fire agreement, Hamas released all 20 living hostages on Monday as well as the bodies of eight others (four on Monday and four on Tuesday) in exchange for nearly 2,000 Palestinian prisoners and detainees.
