I don’t like talking about these subjects, but I’ll step out of my comfort zone. According to the story, the mother got a phone call from someone in Gaza claiming she is alive and resides in a hospital in the north-east edge of Gaza.
In reality, some of these people like to rub salt in peoples wound. It’s not enough that your child was murdered and their corpse paraded on the street. But they also need to torture you psychologically.
On top of that, they expect the mother to put pressure on the Israeli army to stop their military operation, even if temporarily, to give Hamas time to organize and regroup.
