Three more Israeli hostages were freed on Saturday in the fifth round of exchanges between Israel and Hamas, as uncertainty looms over the next stage of the Gaza ceasefire agreement as well as the enclave’s long-term future.

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.
