From this source:
Many of the Israeli hostages, according to interviews with family members, returned “malnourished, infested with lice, ill, injured and deeply traumatized,” the Times also reported.
Also important to note, it is likely that some hostages are treated under "acceptable" conditions for propaganda purposes. Also, many hostages' family members were murdered on october 7. So that unto itself very much contradicts with the absurd claim that they were "treated well".
I literally provide resources of evidence and all you say there is "none"??
give me evidence backed by multiple, independent sources. Then I have a look. Otherwise this is nothing but misinformation.
