The families of the three Israeli hostages released Saturday have spoken out about their loved ones’ ordeal in Hamas captivity, saying they hope their suffering provides impetus to efforts to free all those still in Gaza as soon as possible.

The hostages, who were made to give public speeches thanking the Hamas militants who had held them captive, looked frail and gaunt, sparking dismay and outrage in Israel.

Hostages Ohad Ben Ami, Or Levy and Eli Sharabi were released from Gaza in exchange for 183 Palestinian prisoners, after more than 16 months in captivity.
