The last 20 living hostages released by Hamas are beginning a difficult path to recovery that will include rebuilding a sense of control over their lives and following a carefully supervised diet.

David and his friend hostage Guy Gilboa-Dalal were separated in the tunnels and denied food so they would appear skeletal for filmed “proof-of-life” clips, with food restored only after filming. Viewers around the world were shaken by a Hamas video showing Israeli hostage Evyatar David emaciated and digging what he said was his own grave almost three months ago.

Hamas still has not returned remains of Itay Chen, Omer Neutra and 17 others, threatening the fragile ceasefire in Israel.

Turkey dispatched a team of specialists to help retrieve remains buried under the rubble, but the group was still waiting Friday for Israeli permission to enter the territory.
