Here is what Haaretz -leftist Israeli newspaper- had to say:
However, at Shura Base, to which most of the bodies were taken for purposes of identification, there were five forensic pathologists at work. In that capacity, they also examined bodies that arrived completely or partially naked in order to examine the possibility of rape. According to a source knowledgeable about the details, there were no signs on any of those bodies attesting to sexual relations having taken place or of mutilation of genitalia.
In the course of their work, which included photographing faces only and covering the victims ahead of their evacuation, more than 200 bodies were documented. These teams did not document a single case of sexual assault or cases of genital mutilation. They did see women whose throats had been cut and men on whom "confirmation of kill" had been carried out at close range.
Beyond this, from inquiries put to three bodies in the defense establishment by Haaretz, it emerges that the intelligence material collected by the police and the intelligence bodies, including footage from terrorists' body cameras, does not contain visual documentation of any acts of rape themselves. Overall, the police and the State Prosecutor's Office refuse to make public details of their investigation, which, they say, is in progress. The many obstacles in its path were present from the outset.
