Firas Press reproduces a report from some other newspaper (which they never cite, but this one might be Egyptian) that claims that many of the recent "work accidents" and tunnel collapses in Gaza have really been murders.
The article goes through a number of specific examples going back to November. For example, one of the supposed victims of a tunnel collapse had a gunshot wound. The family of a"work accident" victim also from November disputes Hamas' account.
Even some of the explosions were engineered by other Hamas members, the report says, as some victims were targeted in their cars (and, indeed, there has been a marked increase in the number of car bombs in recent months, usually directed to security forces, that Hamas dismissed as being done by "teenagers.")
The report also details a story about a woman, who had considered Hamas to be her "brothers," abducted by Hamas. Her family found her in the hospital where she says that she was beaten and her abductors threatened to publicize indecent photos of her.
