Israel and Hamas completed their fifth hostage-prisoner swap under a fragile Gaza ceasefire deal on Saturday, with the frail, disoriented appearance of the three freed Israelis sparking dismay among their relatives.

The first phase of the ceasefire calls for the release of 33 hostages and nearly 2,000 prisoners, the return of Palestinians to northern Gaza and an increase in humanitarian aid to the devastated territory. Last week, wounded Palestinians were allowed to leave Gaza for Egypt for the first time since May.
