Israel received the three hostages after Hamas paraded them Saturday before hundreds in the Gaza Strip ahead of their release. Dozens of Palestinian prisoners will be freed in return.

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.

It will be the fifth swap of hostages for prisoners since the ceasefire began on Jan. 19. Eighteen hostages and more than 550 Palestinian prisoners have already been freed in that time.
